Original subtitles

(To become as strong as iron,)

- We can do it. - We can do it.

(they must get through three hurdles.)

(Swimming)

(From a complete novice who swam...)

(while holding a swimming kickboard...)

(to trying open-water swimming in just one and a half months)

(She got used to it after the first sea swimming.)

(In just two and a half months, she even swam across the Han River.)

(Dark underwater and strong currents)

(Still, there was no giving up.)

(She is conquering swimming with an indomitable will.)

(Cycling)

(She was a total novice who couldn’t even pedal properly,)

(but starting with the first outdoor cycling in Yangpyeong,)

(she overcame her fear with clenched teeth.)

(Following the long-distance cycling in Jeju Island,)

(they had an uphill training in Sammaksa.)

(A very tough, nightmarish training)

(Iron Girls overcame their limits...)

(and improved.)

(Running)

(The past themselves had trouble running just 5km.)

(A 10k marathon)

(They believed in themselves and ran until the end.)

(They shortened their records and finished running 10km.)

(Iron Girls are becoming closer to having bodies as strong as iron.)

(Then what kind of training do they need now?)

(This place is waiting for them with a special training session.)

(A semicircle with a bridge in the middle)

(A 5m deep diving pool)

(What special training will take place here today?)

- Hello. - Hello.

What is it?

(They enter with strange baskets.)

Hurry up!

Why did you bring bicycles into an indoor swimming pool?

(Beside the swimming pool...)

(are bicycles?)

Coach Heo says all national athletes go through this training.

- Really? - Exactly this routine.

I’m serious.

When we prepare for the summer games and the Asian Games,

we go through this training in the Jincheon National Training Center.

(We’re going through the training that’s for national athletes?)

Today’s training will be tough.

We’ll go through the training together today.

It’s called muscle switch training.

(Muscle switch training)

(The muscles you use for swimming)

(The muscles you use for cycling)

(The muscles you use for running)

(You use different parts of your muscles for triathlon.)

When you switch from a sport to another,

(Swimming to cycling to running)

you use different parts of your muscles.

That’s why we call it ”muscle switch training.”

Triathletes don’t just run.

They run after cycling, for example.

They go through muscle switch training habitually.

If you don’t get used to the switch,

no matter how much you train,

you don't perform well since you can't switch your muscles.

And you get muscle cramps. It’s called “brick.”

You must get used to it through muscle switch training.

The part where you use most of your strength in triathlon...

is the first 5 to 6km of cycling after you finish swimming.

For the Tongyeong course, it’s an uphill road from the start.

(Moreover, the Tongyeong cycling course is uphill from the start.)

- It’s perfect. - Then...

when you start cycling uphill immediately, your legs cramp up.

Since it’s an uphill road, you’ll feel tired.

To endure it, you must go through this training.

You’ll be divided into teams for the training today.

Uie and Seo Yeon are on the same team.

Two of you are on another team.

It will be in the form of a relay.

(Relay muscle switch training)

Today, you’ll swim 300m.

After swimming 300m, you will cycle 5km on your bike.

(Swimming 300m and cycling 5km)

You start by touching this handrail.

Go.

The next person will do 300m and 5km respectively too.

(The same training of swimming and cycling)

And it goes back to the first person for the next round.

Each person will do it twice.

(The 1st and 2nd sets: Swimming 300m, cycling 5km)

We need to train for the transition area too.

(They will train for the transition area today too.)

(He gets changed quickly and correctly.)

Nice.

He removed the swimming hat and the goggles last.

You need to put them in too.

- Put them in too? - Yes.

- You must do exactly the same. - Put on the helmet.

(Putting the helmet and the shoes quickly too)

Put on your shoes.

Get on it and cycle 5km.

(A real-life training of the transition area!)

During the training session today, you must train until you feel...

that you’re getting too exhausted.

This training session is only useful that way.

Rather than the relay itself,

it focuses more on testing your limits.

- Of course. - A battle with myself.

We won’t just watch you from the sideline.

We’ll keep pushing you.

Physical training is my specialty. I’ve done that my whole life.

I can tell just from your face.

- How scary. - Okay, let’s go.

(Today’s training goal)

(1. Muscle switch training with two consecutive events)

(2. High-intensity training to push them to their limits)

From what I can see, those starting the training...

are Uie and In Ah.

The second trainees are Ju Hyun and Seo Yeon.

All right.

You must concentrate and train.

Give it as best as you can.

Ready.

(Relay muscle switch training)

Let’s go.

(Swimming of the 1st set starts.)

(The 1st trainees, In Ah and Uie get going.)

- Let’s go. - She’s fast.

(In Ah, Uie)

(Swimming as fast as they can from the start)

She’s fast. Look at Uie.

- She’s good. - Good.

Doesn’t she swim well without splashing water?

(With big movements)

- She’s really good. - I literally got chills.

- She is so good. - I can feel her energy.

She is a professional swimmer.

(Ace Uie the Mermaid)

(Uie has already arrived at the turning point at 25m.)

(In Ah swims after Uie quickly.)

(Mermaid Seol is nearly as fast.)

- I’m getting chills. - This is amazing.

They are amazing.

Their hard work is paying off.

(Mermaid Seol versus Uie the Mermaid)

(They swim as fast as they can.)

They glide so smoothly.

(The two aces swim nonstop without a break.)

Uie, it’s your final lap.

The actual course is 1,500m and 40km,

but you’re just doing 300m and 5km.

(Uie the Mermaid finishes swimming 300m first!)

(Uie's 1st set of 300m swimming: 5 minutes and 32 seconds)

You need to do it one more time.

(Converted based on the current pace)

(27 minutes 40 seconds for 1.5km swimming)

(Without resting,)

I think you can go one more round.

(she enters the transition area.)

Quickly. Be calm.

Think about what you should do. That’s it.

Okay, good.

(As quickly as she can!)

Don’t fall. Yes.

(She takes off the wetsuit.)

- That’s it. - Good.

- She’s fast. - You’re doing great.

- She’s fast. - Nice.

(She puts on her helmet.)

She did it.

I’ve never seen someone putting on her socks so fast.

Even when she’s wet.

(She finishes getting changed in a flash.)

Wear your helmet properly and put your stuff in it. Yes.

- Okay. - Get on the bicycle.

Let’s pedal. Ready.

Start. Yes. Start pedaling.

- Cycle 5km now. - Okay.

- You’ll see it. - Check the distance.

(Meanwhile, In Ah...)

(is finishing her final lap.)

(She gives it her all until the very end.)

Come out.

(In Ah's 1st set of 300m swimming: 6 minutes and 43seconds)

That’s it.

Watch out. The floor is slippery.

- Take your time. - It’s slippery.

- It’s so tough. - Good job.

(But there’s no time to express how tough it is.)

- This is no big deal. - In Ah, get on the bike.

You only have five minutes.

Let’s go.

(Transition area: 1 minute and 16 seconds)

Go.

Shift the gear up.

Good, more. That’s it.

(Let’s cycle 5km.)

That’s it. Cycle harder.

Harder. That’s right.

- You should speed up. - Yes.

Cycle until you feel a burning pain in your thighs.

(It’s not easy.)

(Only after 1 minute of cycling,)

(Uie shuts her eyes tight.)

(The pain hits her with the muscle switch.)

She can't pedal hard.

You are switching your muscles now.

Muscle switch takes place while you endure the pain.

(They must endure the pain of muscle switch now.)

Okay.

Cycle faster and harder.

More.

I don’t think you’re panting. Cycle until you’re out of breath.

Yes, shift up your gear.

You shouldn’t pace yourself for this training, right?

That’s right, don’t pace yourself until you hit 5km. Okay.

Shift up the gear.

- Okay. Pedal harder. - Good.

That’s it. Don’t pace yourself...

until you hit 5km. Okay.

You’re already halfway through.

(Suprised)

It’s the face of Mad In Ah.

(Mad In Ah)

(She is smiling as she is cycling.)

(Her gaze changes completely.)

You must cycle until you’re exhausted. Harder. Yes.

- In Ah. - You can do it.

(In Ah clenches her teeth and hangs in there.)

- This is so hard. - It’s 1.6km.

- Harder. That’s it. - In Ah.

It’s 1.9km.

(Monitoring her closely)

That’s it.

Good. In Ah is doing it properly.

Okay. Cycle as hard as you can.

You must push yourself to your limit when you train.

- Look at her sweating. - Okay.

- Keep pedaling. - You’re really amazing.

- I want to work out at a gym too. - Okay.

Open your eyes, In Ah.

(It’s heated up like a real match.)

Maintain the speed. You’re doing well.

For In Ah, it's 3.4, and now 3.9.

- It’s still 500m. - The distance is 500m.

You’re the best partners.

(They are maintaining the 500m distance between them.)

Okay, you have 900m left.

- You can get ready to go in now. - Okay.

- Seo Yeon, get ready. - Get ready.

(Seo Yeon, the next swimmer, gets ready.)

- The last spurt. - Almost there, just a bit more.

- You only have 700m left. - Let’s go.

- Okay. You have 400m left. - Just a bit longer.

- Just 200m. Go. Okay, 150m now. - A bit more.

Keep pedaling.

More.

Okay, stop. Get off. Yes.

Be careful.

(Uie's 1st set of 5km cycling: 13 minutes and 46 seconds)

Put it down.

Take a short break.

(Based on the current pace, 1 hour 50 minutes 8 seconds)

Start swimming when she touches the handrail.

Go.

(Seo Yeon starts swimming as Uie touches the handrail.)

(Seo Yeon starts her 1st set of swimming.)

This isn't easy.

(She continues swimming without a safety buoy.)

(Seo Yeon suddenly stops halfway.)

(She is unable to continue swimming...)

(and arrives at the turning point feeling flustered.)

(With the training that's getting as harsh as an actual match,)

(is she feeling an emotional pressure?)

(But she must overcome it now.)

(Seo Yeon takes a deep breath and starts swimming again.)

(She stops again shortly after.)

(Can she overcome the mounting emotional pressure...)

(and complete swimming?)

- You have 100m left. - Good.

Just 100m. Good. It’s looking good.

There, the last spurt.

It’s 4.95km.

(She uses up all her strength and makes a dash.)

- That’s it! - It’s 4.96km.

- Good. - It's 4.97, and now 4.98km.

It's 4.99km.

- Okay, that’s the end. - Okay, stop. Get off.

- In Ah took 21 minutes 20 seconds. - Take your time.

(In Ah's 1st set of 5km cycling: 13 minutes and 38 seconds)

(Based on the current pace,)

(1 hour 49 minutes 4 seconds for cycling 40km)

Go slowly and touch it.

(She takes off her helmet and shoes right away.)

- You can do it! - Let’s go!

- Go! - She started...

at 21 minutes and 37 seconds.

(After she touches the handrail, Ju Hyun starts swimming.)

(Her soul is out of her body.)

(She doesn’t even have the energy to stay seated.)

(Ju Hyun starts her 1st set of swimming.)

It’s so good.

Drink some water.

You should continue swimming.

(Seo Yeon is staying still.)

Let's see.

(Coach Heo approaches to cheer her up.)

You should swim!

(It's time you should swim!)

No one can help you there.

Start already!

(Coach Heo scolds her severely.)

(She can't let the fear engulf her like this.)

(Seo Yeon finds the courage again.)

That's it!

(Seo Yeon finds the courage again.)

(Only 1 month is left until the actual competition.)

Turn!

(You have no time to stop.)

Okay. Start!

(She catches her breath...)

(and starts again.)

(Seo Yeon)

(She swims fast, overcoming her fear this time.)

- Okay! - Nice, Seo Yeon!

Good. Get ready.

Okay. Relax. Move your feet.

- Let's go. - You got this!

(Her pace is getting faster too.)

That's it!

That's what I wanted to see from you!

Keep up the pace. You're doing so well now!

- Your pace is so good. Okay. - Focus until the end.

- You can make it. - Nice.

(And there's someone...)

(who is silently proceeding forward.)

(She keeps swimming without stopping at the turning point.)

Nice, Ju Hyun.

I see how hard you practiced.

You've gotten even better than the last time at the Han River.

(She became better than the last training at the Han River.)

Your effort finally bears fruit.

Ju Hyun, it's the last lap!

(It's already her last lap.)

(She's proving...)

(how hard she has trained so far.)

(She's about to finish her 1st set of swimming.)

- Please come up here. - Let's go!

Come up already!

- You've done a good job. - Hurry up!

Okay. Relax and change it quickly.

(One step)

(Two steps)

Do it slowly. Be careful.

You've done a good job. Take your time.

You made it. Don't worry.

- It's so hard. It's killing me. - I'll go put on the wetsuit.

I thought I was a goner.

You've done so well.

Focus and ride on it.

Set, go. Nice.

(Ju Hyun starts her 1st set of cycling.)

Do it! Good! More!

- Shift the gear up. Okay. - Yes.

(She shifts the gear into the highest one.)

- Shift it up. One more. - One more.

Okay. Put your strength on it. Good!

The gear is high, but you're still doing good.

You see in the monitor? It shouldn't go below 120.

Okay. That's it. It's 125 and 130. Continue!

Use up all your energy in the early stage.

(She's already dog-tired.)

- Pedal harder! It's 400. - You can do it.

- That's it! - Nice.

(Your pain is my happiness!)

- Let's go. - Don't put pressure on your ankle.

- It's the last 400. - It's 120 now.

(She's surrounded by Captain and Coach.)

- The last 400. You can do it. - Where do you feel hurt?

It's okay that your ears hurt. Let's go!

- It's almost killing me. - Let's go!

- Gosh. - Amazing.

(All she can say now is this.)

- You will finish it soon. - I should hold out.

(Hold out.)

It's 1km now.

(Ju Hyun cycled 1km for 2 minutes and 56 seconds.)

- It's almost killing me. - Let's go!

Gosh.

Amazing. You will finish it soon.

I should hold out.

(All she can say now is to hold out.)

It's 1km now.

(Ju Hyun cycled 1km for 2 minutes and 56 seconds.)

You're doing well!

- The power is 100. - That's not enough!

That's not enough! It should be at least 130.

It should be 130. You heard it.

(A brutal glare)

(I need power!)

You can shift the gear once again, depending on how you feel now.

- Nice. It's 140. What's happening? - It's enough?

You should find the right one.

It was going well earlier. It's 113 now.

- It's 126, 127. Nice! - Good job!

The number shouldn't fluctuate.

Even if it's hard, you should try to keep the same number.

Continue. Yes, everyone groans with this.

- It'll be easier in the real game. - Sure. This is special training.

(Her pain is beyond the imagination now.)

(Wiping her sweat)

Is it my tear?

The power is 120. That's good.

(She's wiping her sweats, tears or whatever.)

You've finished 3km long so far.

This is about how we hold out, so let's do a little more.

Let's go!

(In the meantime, Seo Yeon has only one lap to go.)

You even crossed the Han River, then what are you afraid of?

Compared to that, it's a piece of cake, isn't it?

Good. Relax!

Ready, start!

(Yes, I left all my fear of water...)

(on that day at the Han River.)

Relax.

Good.

You also have to cycle after this.

Don't even think of lying down after this. Okay.

(She overcomes her fear...)

(Seo Yeon)

- That's it! - She's finally coming.

Let's see if she's fine.

(and heads to the finish line.)

(Seo Yeon's 1st set of swimming: 16 minutes and 1 second)

Come up already!

(Seo Yeon's 1st set of swimming: 16 minutes and 1 second)

Come on up!

(1 hour 20 minutes 5 seconds for swimming 1.5km)

You got this. You can do it yourself.

Calm down and do it.

Relax. That's it.

Calm down.

(With her current pace, she can't make it within the cutoff time.)

- Okay. - You're literally doing it alone.

Okay. Get ready. You swam 300m on your own.

- It's amazing. - Good job.

- Take off your goggles. - You made it. Good job.

(She should catch up with others while cycling.)

(She's ready now.)

You're short of time now.

You should make up for your swimming here.

- It's 44 minutes... - Swith the gear up.

Gear up. That's it.

That's it. You're doing so well!

- It's 280. It's 260. Oh, my. - Nice.

- It's 280. It's 260. Oh, my. - Nice.

- You're a professional cyclist. - Gosh.

(Impressed)

Gosh.

(Ju Hyun's current power is 150. Is that really possible?)

(This is not the sound of her groans.)

(Amazing pedaling.)

She's so cool!

(At least, this is my specialty!)

Oh, look at her.

Nice!

- How could you ride that fast? - Okay. Nice.

- She's making it all up. - She's doing so well at this.

I'm serious.

(While Ju Hyun, who is cycling next to her...)

- It's the last 100m! - The last 100m!

(Okay. I'm ready to go!)

Ready.

- Done. Get off. - Okay. That's it.

The record is 45 minutes and 27 seconds.

(Ju Hyun's 1st set 5km cycling: 14 minutes 39 seconds)

Nice. Good job.

(1 hour 57 minutes 12 seconds for cycling 40km)

You should take your time.

You should touch it.

Okay. Start!

It's 45 minutes and 45 seconds now.

Okay. Start!

(In Ah's starts her 2nd set of swimming.)

You did a great job. Give me a high-five.

We'll go one more round. Exactly the same.

(As soon as the set begins,)

(she dashes forward.)

(She's already at the turning point.)

- She's so fast. - She's improved a lot.

- It's three laps now. - You've finished the half. Good.

Nice.

(Mermaid Seol keeps up her pace.)

She's way too fast.

I hope she comes here slowly.

- That's it. I know how you feel. - That's right.

She's way too fast now.

- You're too fast! - Time flies when you take a break.

That last two!

(Thanks for your compliment!)

Okay. Nice!

(Please come slowly.)

It's already 2km?

She cycled 2km within 6 minutes.

(No matter how hard it is, she never stops her pedaling.)

Get ready now.

You had a long break, so you should try harder. Okay?

You had a longer break.

Nice. She's doing well.

It's 52 minutes and 44 seconds.

(In Ah's 2nd set of 300m swimming: 6 minutes and 57 seconds)

(34 minutes and 45 seconds for swimming 1.5km)

Come on up!

Run gently.

You did a great job.

- Ready. - This is crazy.

Put more strength at first. The gear is pretty low now.

Shift the gear up. Higher. Okay. Push hard at first.

- Nice. - Why isn't it getting heavier?

Then shift it up once again.

(It's still too easy.)

- Nice. - It won't change.

- Wait. - It's broken.

It's not working.

Try the one over there.

(The bicycle got exhausted before In Ah did.)

- Let's take on Ju Hyun's. - It was 4.4.

(She hurriedly gets on Ju Hyun's.)

(She gets ready once again.)

Ready.

(She gets ready once again.)

(The owner of the bicycle approaches.)

How about breaking this one too?

- I'll try. - Yes.

(Giggling)

Not much time is left.

(Seo Yeon, In Ah)

Nice.

(Seo Yeon's power is still higher than In Ah’s.)

(Gasping)

Do you hear her gasping?

It's 120. That's nice. Keep up the current pace.

- It’s 4km over now. - Okay Do more!

You have a strong willpower. The last spurt.

- It's 200 now! - It's 140!

That's it!

- It's increasing. - Don't think further.

- Good. - This is nice.

More. Good!

It's 190. Now 210!

It's 230!

(Power 190! 210!)

It's 230!

- Did you say 230? - It's 230!

- Did you say 230? - It's crazy.

- This is great. - It's 230? That's crazy.

Don't think further. Do whatever you can.

The last 100m.

(No one can stop her.)

You have 40m left. Now 30m.

Now 20m left, and 10m. Finish.

- Get off slowly. - You can do it!

(Seo Yeon's 1st set of 5km cycling: 14 minutes and 40 seconds)

(Based on the current pace,)

(1 hour 57 minutes 20 seconds for cycling 40km)

Is it Uie's turn now?

(Go, Uie the Mermaid.)

Let's do this!

(Yes, ma'am.)

(Uie starts her 2nd set of swimming.)

(Uie the Mermaid swims even faster after a long break.)

Since Uie started swimming,

you need to get ready again, Seo Yeon.

- One hour... - Recover well first.

(Help me.)

Okay, good.

- Can you keep up the power? - No.

- Shall we try? - No.

- Let's try until you can. - No.

- Let's try everything you can. - No.

You can do it.

You have the energy to talk.

I won't talk anymore.

Make use of the training with your best effort! Yes!

- I'll get ready. - You can do it!

- Good luck. - You can do it.

(I hope Uie swims slow.)

Good job.

You made 4 laps.

Your pace is great. You're like a pro.

This is...

(To Uie the Mermaid, being in the water is relaxing.)

She doesn't need to make turns at the actual competition.

The record will be a lot better than this.

I have 1km left!

The last lap of swimming today!

(In Ah is doing her best, but she gets serious.)

My knees are in so much pain.

(In Ah is doing her best, but she gets serious.)

Do your knees hurt? Then let's make it rotate.

Let's shift the gear down. Good.

(What happened to In Ah?)

The doctor said it was iliotibial band syndrome.

I need to ice my knees as frequently as possible.

And I was told to lower the intensity of the training.

I should relax my muscles.

(She's been training without expressing her pain.)

It hurts so much.

Shall we stop?

Then shift the gear down.

(She continues cycling while enduring the pain.)

It's your last lap!

It's your last lap! Over here.

- Finish! - It's done!

It's cycling now. You can do it!

You can do it!

(27 minutes and 30 seconds for swimming 1.5km)

(She managed to shorten her record by 5 seconds in the 2nd set.)

(She quickly changes and gets on the bicycle.)

Ready. Start.

(She quickly changes and gets on the bicycle.)

(She starts her 2nd set of cycling.)

Start pedaling and adjust the gear.

(Glaring)

(I’m determined to complete the muscle switch training session.)

- It's 130. - Yes.

This is...

(In Ah continues cycling despite her knee pain.)

(But the pain is getting worse over time.)

- Stop it. - Her knees are in pain.

Don't push yourself too hard. You can stop.

You did what you had to do.

- My knees are burning. - Stop.

Here?

(She stops because of the pain.)

(In Ah's 2nd set of 1.4km cycling: 11 minutes 50 seconds)

You finished what you had to do.

- You have only 900m left. - You finished it.

My knees are almost gone.

(Ju Hyun, please take care of the rest.)

Go slowly.

(Ju Hyun starts her 2nd set of swimming.)

I'm in pain.

(In Ah sits down as soon as Ju Hyun starts.)

(What's greater than the pain is the regret of not finishing.)

You've come halfway now.

Catch your breath.

(Her eyes are still glaring.)

Now,

you're done after 2.5km of cycling.

- Yes. - Okay.

She's already at 130.

(She maintains her power.)

You should go to Australia next year.

I want to train her as an athlete.

Seriously.

- I want to train her as an athlete. - Seriously.

- I mean... - For real.

- I want to train her as an athlete. - Maintaining the power of 137...

looks easy for her.

She's like a European athlete.

Why is Ju Hyun so good?

(Ju Hyun is improving even at this very moment.)

When did she improve her swimming?

She's swimming 100m in 2 minutes and 30 seconds.

- Good! - You're doing great.

With your current pace, you'll make it in 37 minutes!

- Did you say 37 minutes? - Yes.

She turns very well.

(Her current pace is faster than the 1st set.)

She improved so much.

She's doing great.

- Finish! - Finish!

- Good! - You got this!

- Good. - You're doing great!

- Ju Hyun, you're amazing. - Your pace is crazy.

It's 37 minutes.

If you were in the match, it would be 37 minutes.

It's 37 minutes and 30 seconds. This is amazing.

(37 minutes and 30 seconds for swimming 1.5km)

- You're good. - Stay calm.

- Stay calm. - Take it slow.

Take it slow. You can do it while sitting down.

Get on.

- Here. - My goodness.

Your legs are weak now.

(After the second swimming, her legs got weak.)

Put it on.

(Ju Hyun starts her 2nd set of cycling.)

That's it.

(Ju Hyun starts her 2nd set of cycling.)

(She quickly hydrates herself first.)

You can do it!

Let's do this. Shift the gear up.

Make it higher.

Okay. Maintain the pace.

- Maintain this. - Okay. Good.

- You're doing great. - Maintain this.

That's it. Make your thighs burn.

It's about enduring the buildup of lactic acid.

- Good. - It's crazy.

Your power is crazy.

It's 143. Now it's 146.

Your last 300m.

(Let's do this.)

Good. This is your last part of training.

It will be over after this.

Good! It's 200!

You're crazy!

The last spurt. Think of it as your finish line!

The last 80m!

Your power is exceeding 140!

Good!

You have 20m left! Pedal until the end!

Great job. Okay.

(Uie's 2nd set of 5km cycling: 13 minutes and 47 seconds)

(1 hour 50 minutes 16 seconds for cycling 40km)

It's not over yet. Focus until the end.

- Good! - You can do it.

It's over.

Good. She's amazing.

(Seo Yeon starts swimming.)

Seriously.

(After the final touch,)

Do you feel pain anywhere?

(she lies down at her spot.)

You did so well.

My goodness.

- My goodness. - My goodness.

- My goodness. - My goodness.

- Here you go. - My goodness.

- Here's the water. - My goodness.

- You're amazing. - This is crazy.

- You did very well. - I'm in trouble.

- Run! - Good!

(Hard-core Childish Park)

You're awesome!

You need to have a fierce determination.

- Ju Hyun has a determination. - Of course!

- The last 4.7km! - You left some energy for this.

- The last 300m! - Let's go!

- It's your last 300m! - Park Ju Hyun, you can do this!

- You can do it! - Look in front.

- Boktteong! - Now 210m!

Now 210m!

Boktteong!

Boktteong is waiting for you.

You made it turn red!

- You have 20m left! - You have 20m left!

- Your last 10m! Speed up! - It's 10m!

Okay, finish.

(Ju Hyun's 2nd set of 5km cycling: 15 minutes and 11 seconds)

(2 hours 1 minute 28 seconds for cycling 40km)

One, two, and three.

- Team Girls, finish! - Finish!

(Team Girls completed the muscle switch training.)

Okay.

This is your last lap.

Okay. Good.

She swims forward effortlessly.

- She glides like crazy. - Yes.

She's powerful so she can swim forward effortlessly.

- She's so good. - She moves forward so quick.

She's great.

She reaches the turning point very fast.

(She reaches the turning point very fast.)

Okay. Let's do this!

(She catches her breath calmly.)

(Then she starts swimming again.)

(Seo Yeon tries her best until the end.)

She's almost done. It's amazing.

Finish.

- Okay! Good! - Okay!

Come on up!

- Okay! - Come on up immediately!

Get up here!

(She's come one step closer to finishing the race.)

(Seo Yeon starts her 2nd set of cycling.)

Let's go. It's your last cycling.

You can go home after cycling 5km.

The end.

Pack your bags to go home.

(I'll make you all go home.)

Good.

- She's cool. - She'll finish it in no time.

I think she'll catch up with everyone in cycling.

- She's already in 500m. - Already?

- She's already in 500m. - Okay!

Everyone is adapting...

to the intensity of the training better than I expected.

- I know, right? - Yes.

Everyone must've thought I wouldn't be able to swim.

(Everyone must've thought I wouldn't be able to swim, right?)

You're a bit scary. Focus!

Everyone is adapting...

to the intensity of the training better than I expected.

- I know, right? - Yes.

Everyone must've thought I wouldn't be able to swim.

(Everyone must've thought I wouldn't be able to swim, right?)

You're a bit scary. Focus!

- She's scary. - She's reciting a monologue.

- Captain, please say... - Yes.

that I won't be able to make it.

- Say the opposite on purpose? - Yes.

I don't think you can make it.

If you think so,

- I'll make it. - It'll be difficult.

She'll bite the bullet.

- I think so. - I'll make it happen.

Her power is increasing.

It's 140 now.

I think you'll get tired soon.

You'll get tired soon.

If not, you would've been a national athlete by now.

You know, your ending is...

- completing the race! - Completing the race!

Our ending is all set.

Good!

(Screaming)

You hit 2km already!

(From Iron Mentality, she turns into a Fanatic Mentality.)

She's going crazy!

- You're almost there! - It's crazy.

She lost her mind.

Our ending is all set.

- Wait. - Completing the race.

Call the ambulance. Hurry.

- She's amazing. - She's not in her right mind now.

(Fanatic Mentality from the fiery pit.)

You're amazing. You're completely immersed.

- Let me know when I have 300m left. - Okay.

- Three, two, one. - One.

- Let's go. Okay! - Go!

- Let's go! - Go!

- Break it! - Go!

Let's go.

(She's 100 percent focused.)

Is it 300? What?

(3-seconds power)

(The power reached 300.)

- Is it 300? - You're right.

It reached 300 and then it went down.

(Is this even possible?)

- You have 17m left. - Is it 300? Keep up the pace.

- Good. You're awesome. - Your last 100m!

- Last 100m! It's hard, for sure. - The last 100m is easy.

Think of burning your thighs.

(Full-speed)

Good. It's 166!

Burn all the fat! You're doing great.

- Seo Yeon. Three, two, - Keep going!

- one! - One! Keep going!

- Okay! - She finished the race.

(Seo Yeon's 2nd set of 5km cycling: 14 minutes 30 seconds)

(1 hour and 56 minutes for cycling 40km)

- Start. Team Iron finished! - Finished!

(Team Iron completed the muscle switch training.)

You did so well.

- Hang on. - It's 1 hour and 32 minutes.

- She's amazing. - You did so well.

She swam very well too.

You're amazing.

(Hurry and come here.)

Where are you going?

We have to do the chant.

- Do what she says. - We have to do this.

- Shout "Iron Girls" to three. - Okay.

- Two, three, Iron! - Girls!

- Iron Girls! - Iron Girls!

- Okay! - We did it!

Lie down.

(Today's ending is also completing the race.)

Sit down.

My goodness.

(The intense muscle switch training has come to an end.)

It's amazing. You're awesome.

(Last August, during the Jeju training camp)

I'll make an important announcement.

After one month... We have enough time until then.

There will be a triathlon at Samcheok.

I was right.

- A triathlon. - It's not for us, right?

We'll be participating in the competition.

- That's impossible. - I think...

Are we trying all three courses?

We're getting ready for the triathlon in Tongyeong.

So for this, we're going to choose one course each.

We'll participate in a relay format.

You'll be divided into two teams.

The two of you are good at swimming.

So they can be in charge of swimming.

- And you two can cycle. - Cycling.

And all of you will run together.

We can run together.

(Swimming, cycling, running)

(Team A, Team B)

(Team A Swimming: Uie, Team B Swimming: Seol In Ah)

(Team A Cycling: Jin Seo Yeon, Team B Cycling: Park Ju Hyun)

(Running: Everyone)

We don't have much time left until the competition at Tongyeong.

Let's take this chance to challenge two courses.

We're trying a triathlon except for one course.

Let's try triathlon except for one course.

- It's making me nervous. - I'm so nervous right now.

(One month of preparation has passed with nervous hearts.)

(Finally, it's 1 day before the competition.)

(Samcheok)

I brought so many things.

Where is the mirror?

I need to put it on my bicycle.

I need a helmet too.

Don't I look like a hiker?

You're a cutie pie.

(I'm my bags and my bags are me.)

Shall we swim here already?

But today, we're...

here with our bags for the competition.

Doesn't it feel different?

I was excited packing my stuff yesterday.

(Me too.)

Is this seawater?

What's this?

Isn't this the entrance?

- Isn't this the transition area? - The transition area.

My bags will be floating away.

The water level is here now.

(It was sunny in Samcheok yesterday.)

It feels like I'm at a stream.

- Now. - Seriously.

This is crazy.

The water level is here now.

(The venue is filled with water.)

- It's flooding. - Yes.

What should we do in this weather?

- We shouldn't be swayed. - Of course not.

It might be suddenly sunny tomorrow.

- Yes. - That happened a lot to me too.

- He's right. - I see.

As an athlete, you always need to be prepared for a race.

- Until the day of the competition. - Yes.

We're already here at Samcheok so I want to participate now.

- Of course. I hope they proceed. - Of course.

I brought my medal.

- Nice. - My goodness.

- You hung it here. - The previous one?

- What is this medal? - From the marathon.

From the 10km marathon.

I don't want to look like a rookie.

- I shaved my arms too. - Me too!

Why?

(Why did she shave?)

- To put the sticker on a clean arm. - But the shoes...

You're amazing.

(I love your attitude.)

What should we do now, Coach?

We'll take a look around the course.

- Let's have a look at the course. - Yes, let's hurry.

- My goodness. - What's that?

- It's too scary to hop on. - What is that?

Is it for us?

(A bus only for Iron Girls)

My goodness. It's our bus!

Since we're an amateur team,

- this is our team bus. - This is awesome.

(Surprise)

- I rode this in high school. - Seriously?

Usually the reporters are here taking photos.

- Shall we hop on? - Yes.

- Goodbye. - Goodbye.

- We can do it. - We can do it.

Our team bus. Get on.

This bus is nice.

(How's the course that they'll see on a team bus?)

(Swimming course: 1.5km)

(Cycling course: 40km)

(Running course: 10km)

We'll check the whole thing from the swimming course...

to the cycling course.

(Preview of the Samcheok Triathlon)

If it rains a lot, even athletes...

take a preview in a car like we do now.

(Interesting)

Since it's raining a lot,

you can't experience the course physically.

So on the bus, try to focus and see...

where everything is.

When I was running a marathon,

I took the wrong course and ran 20km instead of 10km.

My record couldn't be measured.

I noticed at the 14km mark.

- That's so you. - Yes.

The course might be confusing.

- Yes. - You may take the wrong turn.

- Then it would be a loss. - Right.

You have to see it carefully since it's your first time here.

- Let's go. - Let's go.

The first course we're going is...

- The swimming course. - Is it the swimming course?

(Going to see the swimming course at a glance)

I got here yesterday and tried swimming and cycling.

Both the water temperature and visibility were good.

I want to try it out too.

(However)

- This isn't the venue, right? - But they give out immediately.

Is this the place?

Coach, is this the swimming course?

- Yes. - Here?

This is the swimming course.

- We're going to swim here. - It's murky.

(They are surprised because...)

(This is the venue.)

The color of the water is brown.

- It's because of the rain. - The water is clouded.

This is impossible.

(It seems difficult to secure a clear view underwater.)

(It's usually very clear like this.)

(But the swimming course is murky.)

(They get off the bus to check it out.)

What's going on here?

It's like a doenjang stew.

This is more like a cheonggukjang stew.

Yes, you're right.

There are twigs floating everywhere. Look.

- I thought it was a person. - This is almost...

- an obstacle. - This is crazy.

Look at the middle.

You see the things like sawdust there?

It can get into your mouth while swimming.

You have to be careful.

In Ah, what should we do?

- We have to pray. - What should we do?

I'm worried it might get stuck in my teeth.

This is insane.

(The difficulty of swimming is rising sharply.)

The weather tomorrow might be good.

Okay. I'll pray.

(Praying for the weather to be good tomorrow)

We're going to see the cycling course now.

- Yes. - After swimming, you change...

- and start cycling. - I see.

(After swimming,)

(they'll go through the transition area.)

(From paddy fields...)

(to the downtown)

(The 40km cycling course goes through the center of Samcheok.)

The landscape is mostly flat.

- Yes! - The course is amazing.

- Did you say 800m? - We'll have so much fun.

It won't be hard for us.

- It's what we've done until now. - Next to the mountains?

We've never tried training 40km.

No.

My maximum distance is 20km.

It would be fun to ride a bike on blocked roads.

- You'll be so happy. - Not bad.

- We saw no hills until now. - It sounds so fun.

(While Team Cycling is feeling excited,)

(a steep slope suddenly appears.)

- Is this uphill? - Uphill starts from here, everyone.

- Is this the uphill road? - Yes.

(What's this?)

- The uphill course is long. - We're going a bit high.

(The hidden highlight...)

(of the seemingly smooth cycling course)

- It's quite steep. - This is crazy.

It's almost like the uphill road at Sammaksa.

The uphill course is long.

(The infinite uphill road with sharp curves continues for 1km.)

- My goodness. It's curved! - This is almost...

like Sammaksa.

- The uphill course is long. - It feels like Sammaksa.

This is intense.

- The uphill course is long. - It's better than Sammaksa.

- The uphill course is long. - It's difficult.

- You have to take a U-turn here. - Yes.

This is the halfway point.

It'll be very difficult.

(The cycling course looks difficult too.)

If we get to cycle 40km,

let's just finish the race safely.

Okay.

Let's see the last running course.

- Yes. - Nice.

(On clear days,)

(this place boasts such a beautiful view.)

(The running course along the coast of Samcheok)

It's the best running course.

- It must be refreshing. - It looks like Jeju Island.

I only hope it won't rain.

(They are done looking around the running course.)

When you run in reality, you enter here at the end...

- toward the tower. - Okay.

- Is this area under water? - It's all in the water.

This is where we were standing earlier. Is this for real?

- We were standing there earlier. - Where's the transition area?

- It's in the water. - It's flooded.

(This is where the transition area was located.)

- Is it in the water? - We were standing there earlier.

- What? - What?

The water flooded.

- We can swim here. - Is this the transition area?

(The transition area was flooded by torrential rain.)

(The heavy rain...)

(is increasing the water level.)

This is insane.

Everyone, please calm down.

We might not be able to swim, but we can still run.

Isn't the running course in the water too?

The rain is getting worse.

(Would they be able to complete the course tomorrow?)

- Let's go! - Thank you, everyone.

I reserved the best accommodation for you, as your captain.

The transition area...

This way.

Let's say you enter this way after running.

You finish 2.5km and enter.

- I enter. - What do you need to do then?

- Take off your chip. - Take off the chip.

Take it off, and then put on the helmet.

- Then I put the helmet on. - Put it on.

- Hurry. - Use both arms.

Hurry!

- You enter again. What do you do? - I'm entering.

- I get off the bike. - Yes.

Kick. Good.

That's it. Great.

(They check the swimming poses in the room too.)

- We're checking the details. - I know.

Hurry up.

(The day of the Samcheok Triathlon)

(Iron Girls' accommodation, 4:30am)

(The members got up early in the morning.)

- Good morning. - Good morning.

(Good morning!)

We need to put on the uniform.

(Getting ready to go to the competition)

(Iron Girls are getting changed.)

Gloves, helmet,

socks,

windbreaker. Did you pack...

- the windbreaker? - This one?

Right. Bananas.

- Shall I bring them, just in case? - Bananas.

I'm taking all of these.

(Taking bananas for breakfast)

- Let's go. - Let's go.

- Good morning. - Good morning.

(It's still raining heavily.)

Good morning.

(Iron Girls get on the bus feeling nervous and worried.)

(They set off to the stadium at 5:30am.)

Can the competition be held today?

It can.

The rain seems to be stopping.

You have good news. The rain is tapering off.

(They approach the stadium, and the rain tapers off.)

It's not raining at all.

I see a lot of people.

We're here.

They all came in this weather. It's amazing.

(Despite the severe weather,)

(many people are participating.)

- Look. There are so many people. - Right.

So many people are here.

(Crowded)

I guess the transition area is here.

They're waiting to check their bikes.

(Participants at the transition area check their bikes right away.)

- The weather is fine now. - We can have the competition.

Right.

Go first and put on the sticker for cycling.

- Okay. - Yes.

I'm worried about the cold weather in cycling.

I feel so cold now.

- What shall we do? - You shouldn't feel cold.

It feels so cold. I might catch a cold.

Gosh, I feel so cold.

The rain is pouring again suddenly.

(Suddenly, the rain is pouring again.)

The weather keeps changing.

- Seriously... - The weather is changing suddenly.

(They can't predict it.)

- The rain is on and off. - Yes.

(The weather keeps changing.)

Here we are.

(They arrive near the transition area.)

The bike battery is here.

So many people are here, and I feel sorry.

- She feels sorry? - What does that mean?

- What did she just say? - Everyone...

(Iron Girls are surprised to hear the announcement.)

For your safety,

I'm announcing that today's competition is canceled.

The competition is canceled?

- Today's competition is canceled. - The competition is canceled?

- What? - Did you hear the announcement?

For your safety,

I'm announcing that today's competition is canceled...

once again.

We ask for your kind understanding.

- It's canceled? - So suddenly?

(It's canceled so suddenly?)

Earlier, they said it would be on. I guess it's because of the rain.

My goodness. No!

What's happening?

It's my first time to see a competition canceled on the day.

In my career as a triathlete,

- this never happened before. - And we're experiencing that?

He's entered 200 competitions.

But only Iron Girls, but everyone here...

is feeling disappointed.

- I guess so. - Right.

Everyone must be feeling sorry.

(The competition has been canceled for safety's sake.)

I didn't imagine we wouldn't have the competition.

(I didn't imagine we wouldn't have the competition.)

Then what should we do now?

In fact, as your captain,

if you complete the course, I was going to give you...

- A medal? - a dinner party.

(He prepared a dinner party for completing the course.)

It's a well-known restaurant in Gangwon Province.

It's a Korean beef restaurant.

(He booked a Korean beef restaurant in Gangwon Province!)

I made a reservation, everyone.

- Okay! - So let's go to the restaurant.

Let's go.

This show isn't "Tasty Guys".

(Do Iron Girls have a good appetite?)

Here we are.

(Iron Girls arrive at a restaurant near the East Sea.)

Look at the weather. It feels refreshing.

How can this happen in a day?

We should've had this after completing the course...

- with a medal on our neck. - I know.

- But we prepared the meat already. - This can happen.

I ordered a generous amount.

- It looks insane. - This looks so good.

(Korean beef from Gangwon Province looks beautiful.)

The grilling sound is similar to the sound of rain.

- It's the sound of rain. - The sounds are similar.

(Korean beef is grilled nicely in the sound of rain.)

It looks good. I feel happy.

It's nice to look at the sea eating beef.

- It's great. - Right.

It would have been great if it didn't rain.

This is great. This is so relaxing.

(The East Sea on a fine day...)

(is so relaxing.)

I see the sea right in front of me.

You should eat beef when you come to the East Sea.

Eat the first piece only with salt.

(Dip the first piece into salt.)

This tastes so good!

Great.

(She frowns when the food tastes good.)

You need to eat well. Eating is a part of training.

Right.

I should eat this since you prepared it.

(Then I'll take a big bite.)

You're eating well.

(I'll take a big bite too.)

(They eat beef...)

(and slurp naengmyeon.)

(Iron Girls train themselves hard.)

(They keep eating.)

Can we have beef tartare, please?

May we have two more servings of doenjang stew?

(They kept training themselves for a long while.)

(3 weeks later)

Isn't the weather so nice? And the breeze. It's the best.

Right. The weather is helping us.

It's Samcheok!

(Samcheok?)

I can't believe we're back here.

(Iron Girls are back in Samcheok again?)

Is this the same place we came before?

- It is. - It's the same place.

That's the same finish line.

- Look at that. - It says "Iron Girls."

- Didn't they pull it down? - Of course, they did.

There was water here.

(Until the Tongyeong Triathlon,)

(only 3 weeks are left.)

(Iron Girls need practical training.)

(That's why we prepared...)

(a mock triathlon competition only for Iron Girls.)

(Lanes and buoys are set up.)

(A swimming course of 1.5km)

(Consisting of uphill roads and downhill roads)

(A halfway point)

(A cycling course of 40km)

(A high level of physical and mental strengths are needed...)

(for the 10km marathon course.)

(The course is 51.5km, the same as the real competition.)

(Not only safety guards...)

(but also emergency care staff are on standby.)

(Water fountain, transition area, and medals)

We tried to make it close to the actual competition.

We set up a finish line and floated buoys.

We created a whole course at night.

It's unbelievable!

I feel more nervous than before.

(A stadium only for Iron Girls)

- This area was all in the water. - Is this the same place?

- It's the same place. - Are you sure?

I didn't know it was a parking lot here.

Is this true? I can't believe it.

We regretted not being able to have the competition earlier.

But we trained hard every day.

We trained every day shedding blood, sweat, and tears.

(They trained every day shedding blood, sweat, and tears.)

(Although the competition was canceled,)

(our training doesn't get canceled.)

(Now is the time to focus on training the weak points!)

(Seo Yeong focuses on swimming training.)

(Open-water swimming)

(1km on September 30)

(1km on October 1)

(1km on October 3)

(1.2km on October 4)

(Indoor swimming: 1km on September 24)

(1.2km on September 26)

(1.8km on September 28)

(After focusing on swimming training,)

(she swam 2km on October 5.)

(It takes her less than an hour to swim 2km indoors.)

(Uie focuses on cycling training.)

Don't relax your core muscles.

(1 hour on September 23, 50 minutes on September 24)

(1 hour and 25 minutes on September 26)

(Now her posture is perfectly balanced.)

(She challenges the long-distance outdoor cycling!)

(38km outdoor cycling on October 3)

(38km outdoor riding on October 5)

(After breaking the longest distance she ever tried,)

(she easily rides on uphill roads.)

(She even drinks water with one hand off the handlebar.)

(The ace is overcoming her weakness step by step.)

(Which training is In Ah on?)

(Running in the water?)

(In Ah had a knee injury and is receiving treatment.)

(In Ah focuses on rehabilitation.)

("My knee hurts so much that it doesn't feel like working out.")

("It's mentally painful.")

("I keep having a dream of failing the triathlon.")

("I wish dreams would go by contraries.")

("My knees, please hold on!")

Please bend your knees more.

(She feels rushed.)

(The only solution is rehabilitation!)

Keep running!

(With the steady rehabilitation training,)

(she's taking back her pace.)

It's 40km here. We'll go to the Han River.

We'll go 20km and come back riding 20km.

And next, you'll run 10km.

I heard you never cycled 40km outdoors before.

- Is this your first time? - Are you sure I can do this?

- I think you can. - It's my first time.

Okay. You're going at a nice speed.

(Let's conquer two events!)

- I passed 13km. - It was easy, right?

Now let's speed up a bit. Slightly.

There you go.

(Passing 35km)

I feel my muscles are being torn off.

Okay. Stop.

(She completed 40km of outdoor cycling for the first time.)

Good job. It was really nice.

You completed a 40km course for the first time.

How can I run 10km after this?

(She does it with her mental power!)

(She starts running right after cycling.)

You're working out until the sunset.

You're almost there.

Your 50km training is almost over now.

Go. Okay, stop.

(She completes 2 events of the triathlon!)

It's amazing. I'll show you the record.

It almost killed me.

- Okay. It's over. - Okay.

- You can do it. - Let's go.

(She's so exhausted that she stammers.)

What? Say "Iron" now.

- Iron Girls. - Iron Girls.

Okay.

(Now they can't be satisfied with completing one event!)

(Uie trains for 3 events in the Han River.)

(Swimming 1.7km)

(Cycling 3km)

(Running 7.5km)

(Still, she doesn't forget to smile.)

(Seo Yeon has cycling shoes on.)

(In Ah is completely adjusted to cycling shoes.)

(Cycling 30km)

(Running 5km)

Your pace is all right now. It's been five minutes.

(Now she can complete two events at one go.)

(In Ah begins mini-triathlon training.)

(Swimming 200m)

(Training for the transition area just like in a real situation!)

(Cycling 5km)

(Running 2.5km)

(She completes 2 sets of the mini-courses of 3 events.)

(She had muscle switch training for the past 3 weeks too.)

In fact, you have 17 days left until the Tongyeong competition.

Now you have only a few days left. You can even count D-days.

Really? 17 days?

You have 17 days left.

So today, in preparation for the Tongyeong competition,

we'll have our first mock competition.

- I see. - We need that.

Last time in Samcheok,

we were going to have a relay competition.

But today, it's not a relay.

You're going to complete the course alone.

(Challenging a full triathlon course all alone)

What shall I do? Can we do this?

Is it the same distance as in Tongyeong?

It'll be the same, as a full course.

- It's 1.5km... - Swimming 1.5km,

- cycling 40km, - It's 40km.

- and running 10km. - Yes, 10km.

- That's right. - Gosh.

I feel breathless just hearing it.

The cutoff for the Tongyeong competition...

- is 3 hours and 30 minutes. - It's 3 hours and 30 minutes.

- It's so tight. - It's tight.

Right. It's hard to make it.

It's tight even when the transition area isn't considered.

(The cutoff time)

(Triathlon is a record game.)

(If they fail to make it within the cutoff time for each event,)

(they can't continue the competition.)

(The Tongyeong competition's cutoff for swimming 1.5km...)

(is 50 minutes.)

(Cycling 40km...)

(needs to be finished in 2 hours and 30 minutes from swimming.)

(Running 10km...)

(needs to be finished in 3 hours and 30 minutes from swimming.)

(They need to finish the course within the given time.)

(Would Iron Girls complete the course within the cutoff time?)

It's 3 hours and 30 minutes.

- It's so tight. - It is tight.

- I calculated the time. - It is tight.

But today, we won't set the cutoff time.

Considering your physical condition,

- you can take your time. - Okay.

Just do as much as you can.

Our objective is to complete the course, without a cutoff.

You'd wonder how long you'd take...

if you were in the Tongyeong competition.

- You don't know if you can make it. - Right.

It doesn't matter how long it takes...

or whether you complete it or not. Just try it doing your best.

And until the actual competition, work on...

- where you need to improve. - Yes.

Yes, we have no option.

Let's accept our fate.

- Let's experience everything today. - We should.

So, to make it feel like a real competition,

- What? - we invited someone special.

As we prepared a mock competition,

we invited referees.

What?

- It's incredible. - You...

can't break the rules even if it's a mock competition.

So the referees will watch you with a hawkish eye...

to judge whether you break the rules or not.

- My goodness. - They'll check you in detail...

as you proceed with the competition.

First, we'll set up the transition area.

- Okay. - Okay.

- It's amazing. - It's so awesome.

It's unbelievable.

- It looks so nice. - Everyone.

In reality, this is a rack for the elite participants.

But we're not elite participants.

Today, you'll be one.

(A customized transition area for Iron Girls)

It's amazing.

(They start to set up the transition area.)

- Coach. - Yes.

Do I have time to eat a banana?

A banana?

(It's going to be hectic here.)

- I won't, at all? - Why?

And if I get hypothermic,

I need to have jujube tea, as I heard.

This isn't a convenience store, but a transition area.

Are you going to have it in the real competition?

Yes. Don't we get hypothermic?

(Serious)

But would we have time for that, considering the cutoff?

Really?

(What's in In Ah's basket?)

It's all right.

What's this stuffed toy here?

- That's my little guardian. - I see.

What's this?

(A stuffed toy made after In Ah's pet dog Julie)

I'm sorry. I didn't know that.

Wait. She has two of them here.

Wait.

- What are these? - Come on.

- They give me energy. - Is this a tube?

(They give her energy, than I can't take them away.)

- I brought them to swim well. - Wait.

(What's in Uie's basket?)

- This is nice. - It's neat, right?

I practiced it.

(During the individual training,)

(she practiced for the transition area too.)

Uie...

made it neat like she's in the army.

Ju Hyun, have you applied a sunscreen stick on you?

- I need to. - What?

- I need to. - I have one here.

(You shouldn't forget a sunscreen stick even when you're in a hurry.)

Isn't this cute?

- I use this too. - What?

- I use this too. - Do you?

- It's cute, isn't it? - It's so easy to carry around.

And when the sun is strong like this, you need to apply it for sure.

- Right. - You know what I mean.

Even though the summer has gone, the sun is still strong.

You need to be careful about the sunlight in the fall.

You need to apply it all through the year, everyone.

It doesn't feel sticky either.

- All right. Are you done? - Okay. I'm done.

(They set up the transition area.)

- Okay. Are you ready? - Yes!

- Let's warm up. - Go!

Run. Line in pairs.

Let's go this way.

(They warm up first before the competition.)

(They warm up with running.)

(In a more determined manner than ever,)

(they put on the suits.)

(The first event is swimming 1.5km.)

(When the competition is canceled due to the weather conditions,)

(the river wasn't clear because of the torrential rain.)

(Today, it's perfect for swimming.)

(Now, everything is set!)

- I'll explain the course. - Okay.

The white line is the starting line.

- Okay. - And when you start,

you'll swim with the lane on your right.

Then you see the first floating mark in yellow ahead of you.

The second one is on your far right.

- The third one is next to that. - I see.

You get to each point of the lane...

and come to the starting line, and repeat the same once again.

- I see. - Okay.

But from the third floating mark,

you shouldn't swim across to the finish point.

Make sure you touch the endpoint of the line and return.

- Just follow the lane. - Follow the lane.

All right.

On the competition day, you have time to warm up.

You need to warm up before swimming based on your condition.

Okay.

(They're going into the water.)

Goodness, it's so cold!

- The water feels cold. - It's cold.

Gosh, it's so cold!

- It's like ice water. - It's cold.

It feels so cold.

(Taken aback by the unexpected situation)

The water is so cold.

How come the water is cold?

- Oh, my goodness. - I'm scared.

(They practiced...)

(under the blazing sin.)

(August)

(Open-water swimming at Jeju Island)

(September)

(Open-water swimming at the Han River)

(It felt refreshing when they trained in the water.)

(Now, the summer has gone.)

(October, Samcheok open-water training)

(The river in October is colder than expected.)

The water is really cold.

(Will they be okay with...)

(the first open-water training session in fall?)

The water is really cold.

I've never tried swimming in water that's this cold.

- That's cold! - This is no joke.

- That's cold! - This is insane.

It's really cold!

- Ju Hyun is afraid of cold water. - That's cold!

(Ju Hyun is especially afraid of being in cold water.)

- It's so cold. - What do I do?

It's too cold.

We have to move around.

- What do I do? - It's colder than an ice bath.

(While everyone is feeling flustered at the low water temperature...)

Who is that?

(There's someone swimming boldly in the cold river.)

It's Uie.

(It's me, Uie the Mermaid.)

(Uie quickly adapts to swimming in cold water as well.)

(In Ah starts warming up right away as well.)

(She swims forward swiftly again without forcing herself.)

(Uie is already near the floating mark.)

My feet reach the bottom even up to here.

My feet reaches the floor even up to here!

What?

(Starting line, shallow water level, deep water level)

My feet reach the bottom here!

- Even up to there? - My feet reaches the floor here,

Seo Yeon!

Your feet reach the bottom, so feel comfortable.

But try not to touch the bottom.

Okay. I'll give it a try.

(Seo Yeon bravely gives it a try.)

(The captain swims right next to her to focus on her.)

Your pace is a bit too fast.

Your pace is too fast.

It'll be too close if you swim here. You should be this far from it.

- Okay. - Right.

(Seo Yeon swims forward feeling comfortable with the level.)

- Great. Your pace is fast. - It's good.

(Each member is adapting to the cold water.)

(Ju Hyun isn't even in the water yet.)

Gosh, it's so cold.

What do I do?

Walk in slowly.

Watch your step.

- What do I do? - Watch out for rocks.

(She can't seem to go in with her fear of cold water.)

I feel too scared.

What do I do?

Try swimming here.

- Go there? - No.

(Ju Hyun tries putting in her face first.)

(She tries her best to adapt to the cold water,)

I can't!

(but it doesn't seem to work out for her.)

(Uie goes out to help her after watching her.)

Your pace is a bit too fast.

Your pace is too fast.

Are you okay?

It's the first time the water was this cold in an open-water session.

Give me your hands.

- Put them in the water first. - Where?

Just this much.

No. I won't go down further. Look.

Swim freestyle!

Swim freestyle!

(Coaching her strictly)

There you go.

Gosh! I can't move my arms.

I'm scared.

(I'm scared, Uie.)

(She gives her a warm hug.)

But you have to try moving your arms no matter what, Ju Hyun.

Give it a try! You have to, Ju Hyun!

Go for it! There you go!

(With Uie's kind and strict coaching,)

There you go.

(Ju Hyun slowly adapts to the cold water.)

- We have to start now. - Let's get ready now.

(It's finally time for the triathlon real-life practical training.)

It's not a competition and don't worry about your record.

- Just do the best you can. - Right.

Let's try to enjoy it this time.

- Okay. - Okay.

- Let's go! - Let's go!

Let's do this!

- Let's go! - Let's go!

I can do this.

(I can do this.)

My heart wasn't ready for it...

and I wasn't fully trained.

I just wanted to face it and go until the end without giving up.

I can do this.

I can do this.

I felt anxious and worried.

I wished for me to be in a good condition.

Let's go!

(They cheer each other up even while feeling nervous.)

- Take it slow. - Let's do this!

- I love you! - We can do this.

- Let's just finish the course. - We can do this.

It was the first triathlon of the Iron Girls.

I wanted to show everyone what I could do.

I really wanted to do well.

(Will the members...)

(be able to complete the course in 3 hours and 30 minutes?)

Here we go!

(Nervous)

- We'll begin. - On your mark!

(The triathlon begins.)

- Okay! - Go!

Go!

Get into position.

(Uie dives in without hesitation.)

(In Ah and Ju Hyun dive in behind her right away.)

(A smooth start)

Okay. Watch your feet.

(Seo Yeon enters slowly with the captain.)

(Seo Yeon, Ju Hyun, In Ah, Uie)

(At that moment,)

(Uie picks up the pace greatly!)

(With a stable pace,)

(she swims forward.)

(She gets further away from In Ah and Ju Hyun.)

(There's a big gap between them in no time.)

(She has already reached the 1st floating mark.)

(Uie passes the 150m mark in 2 minutes.)

(Ju Hyun, In Ah)

(These two do their best to follow her.)

(In Ah passes the 150m mark in 2 minutes and 48 seconds.)

(Ju Hyun has a good starting pace even in the cold river.)

(Ju Hyun passes the 150m mark in 2 minutes and 55 seconds.)

(Ju Hyun is the last one to reach the 1st floating mark so far.)

(Uie has widened the gap between her and the other members.)

(She passes the 250m mark.)

I want to get a better record in swimming.

Many people know that I was a former swimmer...

and they will focus on me and my swimming.

I'm not sure if I can meet their expectations.

(She feels more pressure to do well because of that.)

(Han River 1.5km record a month ago: 26 minutes and 4 seconds)

(Will she be able to get a better record?)

(Seo Yeon who is the weakest in swimming)

(Starting line)

(She still hasn't passed the 1st floating mark.)

Your direction!

Your direction!

I wasn't able to look forward.

That was why I lost my way and stopped.

(She's taking a longer turn that the original distance.)

(She finds the right direction and swims again.)

(She is last,)

(but compared to the Han River crossing a month ago,)

(her breath lasts a lot longer...)

(and her speed is much faster and more stable.)

(However...)

What is this?

What is this?

Watch out for that. Right.

It'll get deeper now.

When I was going around the corner, I got caught by the rope...

and I got intimidated.

This way.

When I was taking it slow in the sea,

I thought that I had become much closer with water.

But as I was in an unfamiliar area,

it was hard to feel comfortable.

I think I'm still afraid of water.

Are you okay? Let's go.

(She controls her breath...)

(and fights against the new environment.)

Check where you're going.

(Seo Yeon, Ju Hyun, In Ah, Uie)

(Currently, everyone has passed the 1st floating mark.)

(The 2nd floating mark, 375m)

(Uie has reached the 2nd floating mark.)

(She checks the position of the floating mark...)

(and moves right next to the corner.)

(She passes the 2nd floating mark in 6 minutes and 53 seconds.)

(Uie)

(She keeps a fast pace...)

(and even passes the 3rd one in 7 minutes and 21 seconds.)

(While Uie is passing the 500m mark,)

(In Ah heads to the 2nd floating mark...)

(on the other side.)

I was able to check my pace and level.

I thought it was a chance for me.

I had no worries.

(Han River 1.5km record a month ago: 36 minutes and 23 seconds)

(In Ah has gained more confidence. What will her record be today?)

(In Ah reaches the 2nd floating mark in 8 minutes and 27 seconds.)

(In Ah reaches the 2nd floating mark in 8 minutes and 27 seconds.)

(While In Ah is heading toward the 3rd floating mark...)

(Uie, Ju Hyun, In Ah)

(What about Ju Hyun who is in 3rd place?)

The water was cold, and I couldn't see ahead of me.

(At the start, Ju Hyun went against the lane and drank water.)

I drank water during the swim.

(At the start, Ju Hyun went against the lane and drank water.)

I was shorter on breath than usual.

I kept thinking, "Should I stop or not?"

"What do I do?"

I went a lot slower than what I had practiced.

(Current pace: 100m mark in 2 minutes and 50 seconds)

(Ju Hyun is a lot slower with her pace than usual.)

"What if I get cut off?"

"Where am I at right now?"

(As she was losing her pace out of anxiety...)

Great.

That was when Coach Heo appeared.

You're doing great.

Your pace is great.

I felt so comforted.

I became stabilized.

After hearing that, I thought,

"Great! Let's keep this up."

That was when I picked up the pace.

(She is freed from her anxiety and picks up the pace.)

(As her breathing becomes stable,)

(she is able to look forward comfortably.)

(She smoothly switches directions...)

(and reaches the 2nd floating mark in 9 minutes and 49 seconds.)

(Uie, Seo Yeon, In Ah, Ju Hyun)

(Seo Yeon is far behind.)

(She is passing the 220m mark.)

(She stops all of a sudden.)

I got a cramp.

I even got a cramp all of a sudden.

(Seo Yeon got a cramp this time.)

My foot.

(She grabs onto the lane...)

(and gets it treated.)

(Seo Yeon's foot)

I should take the pills that prevent cramps before swimming.

Right. The cramps will keep on coming.

Straighten your knee and calf.

(Her muscles became stiff due to the cold water and her nervousness.)

- How is it now? - I'll try again.

Are you okay?

(Seo Yeon's cramp was treated thanks to Captain Kim.)

Okay.

(I have no time to be like this.)

I must go.

- I must go. - Right away?

(She gets back in the water right away.)

(There's no more time to waste.)

(It took her 11 minutes to the 250m mark.)

(She picks up the pace as she was delayed due to different issues.)

(She still stops for breaks in between,)

(but she goes a lot more at once this time.)

(Captain Kim quietly stays by her side.)

I saw you,

and you seemed to take 15 strokes.

If moving both arms once is one stroke.

So you should take 15 strokes and stop once.

Let's go with this in mind.

We can't be using too much time with breaks, so I'll be checking.

- Okay. - Okay?

(Seo Yeon's short-term goal: 15 strokes for both arms)

Get ready. Go.

(She starts again after setting a new goal.)

(She completes 15 strokes with both arms.)

Doing 15 strokes is around 30m.

(Seo Yeon)

(Around 30m)

Doing 15 strokes 3 times is around 100m.

Right?

If that's too much for you, should we go with 12 strokes?

(If that's too much for you, should we go with 12 strokes?)

I can do 15.

(I will do 15 no matter what.)

(Iron Mentality shows her will after setting her goal.)

(Meanwhile, Uie who is in the lead...)

(is passing the 600m mark.)

(As she gets closer to the halfway point,)

(she picks up her pace.)

(There's 100m left to the halfway point.)

(Uie, Seo Yeon, In Ah, Ju Hyun)

(With a consistent form like that of a machine,)

(Swimming AlphaGo Uie steadily paces forward.)

(The halfway point is right in front of her.)

(She checks her record first with the mindset of an athlete.)

(Uie passes the 750m halfway point in 13 minutes and 12 seconds.)

I can go right away?

(She dives in for the second lap without wasting any time!)

(As Uie sets off for the first floating mark again,)

(one person gets closer from the other side.)

(Uie, In Ah)

(They dramatically go past each other.)

(In Ah)

(In Ah heads toward the halfway point after Uie.)

(As she gets closer to the halfway point,)

(she paces forward lightly without forcing herself.)

(She gets out of the water...)

(and takes big steps.)

(In Ah passes the 750m halfway point in 15 minutes and 42 seconds.)

Is Seo Yeon okay?

(She worries about the eldest during the race...)

(and boldly heads into the water.)

(While In Ah is comfortably passing the halfway point,)

(someone gets closer from the other side.)

(This time, Ju Hyun is heading toward the halfway point.)

(The two go past each other at their own pace.)

(She struggled with swimming in cold water,)

(but she kept her own pace...)

(and completed a lap without taking a break!)

You have to step on the line before you go.

You have to step on the line before you go.

(Oh, right!)

(The rules must be followed strictly.)

(Ju Hyun passes the halfway point in 18 minutes and 37 seconds.)

(Your record won't count if you don't step on the line.)

(Ju Hyun enters her second lap after setting her record.)

(Second lap, second lap, second lap, first lap)

(In Ah is passing the 950m mark.)

Around the second lap,

I felt shivers down my spine.

I felt as if I was swimming with a ghost...

and realized how the coldness could make me feel.

It felt as if my body was shaking.

I was shivering because of the coldness.

It felt like I was going to get a cramp.

And as I was making the strokes,

it felt as if my hands were a bit frozen.

Swimming feels so lonely.

I really felt that swimming was a lonely thing to do.

It's a lonely event.

(A lonely fight against yourself)

Your pace is amazing.

You're doing really well.

You're doing really well.

Good!

(Words of encouragement in the lonely fight)

(Uie's 2nd lap, Seo Yeon's 1st lap)

- It's Uie! - Uie.

Uie is too good.

(Uie has already caught up to where Seo Yeon is.)

I saw Seo Yeon during my second lap.

She was doing a lot better...

than I expected.

I thought that she had gone through a lot of training...

as I went past her.

(Uie and Seo Yeon go past the 3rd floating mark.)

Turn.

(What's left for Uie...)

(is just 500m.)

(She's in the second half of the race,)

(but her pace is just the same.)

(Only 100m left until she finishes the race)

(The goal is right in front of her.)

(One out of three sports has ended!)

(Uie completes 1.5km swimming.)

(Uie, 1.5km swimming, 27 minutes 03 seconds)

(One month ago, 1.5km in the Han River)

(26 minutes 04 seconds)

(Her record becomes 1 minute longer.)

It’s not that I didn’t do my best today.

But due to various reasons,

I didn’t have enough stamina for it, which upset me.

I couldn’t breathe comfortably throughout the whole 1,500m.

It was very cold, to be honest.

(The cold tormented Uie throughout the swimming course.)

I was worried about the water being too hot,

but rather, the water was way too cold.

I learned there were a lot of variables.

Then I should be prepared for all sorts of situations.

(But there’s no time to regret!)

(While Uie enters the transitioning area...)

(First round, second round)

(This time, In Ah swims towards Seo Yeon.)

(Seo Yeon, 1st round, In Ah, 2nd round)

(Gliding peacefully)

(Thanks to swimming nonstop,)

(she only has 100m left until the goal.)

(In Ah is closely behind Seo Yeon.)

(Seo Yeon, 1st round, In Ah, 2nd round)

(In Ah also supports Seo Yeon in her head.)

Okay, let’s go.

- Go. - Let’s go.

(Patting)

(Even while swimming, the members pat each other.)

(In Ah swims toward the goal!)

(She checks the spot again.)

(In Ah completes 1.5km swimming.)

(In Ah, 1.5km swimming, 32 minutes 08 seconds)

(One month ago, 1.5km in the Han River)

(36 minutes 23 seconds)

(Her record became 4 minutes 15 seconds shorter.)

I was quite surprised. I only took 32 minutes.

“Thirty-two minutes? That’s awesome.”

(She got a lot faster than last month.)

You can do it.

(Meanwhile, Seo Yeon arrives at the turning point.)

Let’s go back.

(Seo Yeon passes the 750m turning point,)

(32 minutes 39 seconds)

You can do it.

Let’s do this. Go.

(She ought to be tired from the long swim.)

(But Seo Yeon gets in the water again without resting.)

- I can do it. - You can do it.

(For the remaining one round,)

(she starts swimming again.)

(Meanwhile, Ju Hyun in 3rd place)

(Ju Hyun)

(She is passing the 1,300m mark.)

(She is nearing the end.)

(Ju Hyun keeps swimming away from the lane.)

Breathing on both sides is bad here.

If I breathed on one side, I could’ve kept seeing the lane,

so I could’ve swum straighter.

When I breathed on this side, I was further away from the lane.

(Breathing on her left side)

(After breathing on both sides,)

(she keeps getting pushed to the side.)

(She realizes she is going the wrong way by looking forward.)

(Breathing on her right side)

(Breathing on her right side)

(She switches back to breathing on one side.)

(She controls her breathing and changes direction.)

(She is 100m away from the goal.)

(Needless of her worries about the cold water,)

(she hung in there without a single minute of rest.)

(Ju Hyun completes 1.5km swimming.)

(Ju Hyun, 1.5km swimming, 37 minutes 32 seconds)

(One month ago, 1.5km in the Han River)

(44 minutes 49 seconds)

(She shortened 7 minutes 17 seconds.)

I still did swim really hard.

So I wanted to do well.

(Her swimming has improved significantly.)

(Seo Yeon)

(Seo Yeon is left in the swimming arena alone.)

Are you doing okay?

Are you okay?

Let’s do this.

Go.

Let’s go. It’s 39 minutes now.

(She has about 11 minutes left before the cutoff.)

(Can Seo Yeon finish swimming in 11 minutes?)

(A real-life mock match in Samcheok)

(Their goal is to finish the match in 3 hours 30 minutes.)

(The time limit starts to pressure her.)

(They are at the danger of being cut off.)

(Clank)

(They don’t have much time,)

(but unexpected situations keep arising.)

(An unending fight with the pain)

(Even Coach Heo tries to stop her.)

(A red flag to the mock match)

(Can Iron Girls manage it?)

(The awaited day before the match)

(The Tongyeong match is around the corner.)

(All strong men and women of all ages and nationalities...)

(will gather.)

(The final training in Tongyeong to complete the race)

(They start warming up for swimming in the tense atmosphere.)

(They are caught in a physical fight.)

(Even the ace Uie is blocked.)

(Can they swim in Tongyeong like this?)

(That isn’t the end.)

(Cycling without a break)

(They face the infamous Tongyeong cycling course.)

(Do you want to go back to before?)

(When you’ve been cycling so well?)

(You can’t go back. Never.)

(If I cycle this slow, I’ll get cut off.)

(There’s no backing out now.)

(And an emergency meeting)

(Everyone is on edge.)

(Everyone is on edge...)

(with the match around the corner.)

(The Tongyeong match starts in the tense atmosphere.)

(Iron Girls’ 120 days of journey, how will it end?)
