Original subtitles

(A special training camp in Jeju Island...)

(for Iron Girls)

(Advanced cycling course, )

(cleats training)

(Their shouts filled up the room.)

(The members couldn't balance.)

(I'll show you!)

(Right on the first try, )

(she succeeded.)

(Others made a fuss about how good Childish Park was.)

(A special training for Uie, the cycling novice)

(It wasn't easy.)

(Practice is the only way to go!)

(She completed the indoor course with her passion!)

(They continued with the outdoor cycling.)

(Giving signals)

(Leveled up)

(Speed)

(Leveled up)

(I want to drink!)

(She even drinks...)

(while cycling!)

(Iron Girls have improved a notch.)

(And...)

(She sometimes stopped...)

(and was slow like a turtle, )

(but she didn't give up and aimed to complete the course.)

(Uie cycled slowly.)

(She completed the course safely.)

(All the members of Iron Girls completed cycling 22km!)

(What training awaits them next?)

(The first night of the Jeju training camp, 10pm)

- Does this part hurt the most? - Yes.

- Here? - Yes.

My legs aren't painful at all.

- As you said. It's thin. - That's right.

(During the afternoon's training, )

(Uie tried a long-distance cycling for the first time in her life.)

(She was too nervous...)

(that she tensed her arms so much until her arm muscles showed.)

(My palms hurt so much.)

(Uie got muscle aches with a sense of accomplishment.)

(In Ah's arm massage service...)

(for Uie who worked hard)

By the way, Uie, how more tan are you going to get?

Seriously.

(She was very fair like this.)

(She became like this.)

Am I supposed to be this tan?

I'm getting more and more tan.

What about this side?

This side is fine.

Can someone put the pain relief patch on me?

- Did you bring pain relief patches? - Yes.

- This... - This, and I have another one.

Here.

(A camaraderie blossoms as they put the relief patches.)

This feels so good. It's great.

My toes hurt. I need to massage so many parts.

Bye.

(Disarmed by her goodnight kiss)

Goodnight.

- Bye. - Bye.

(The first day of the training camp which built their camaraderie ends.)

(The 2nd day of the Jeju's training camp)

(Current time: 5am)

Ju Hyun, it's time to wake up. I'll turn on the light.

(Half-asleep)

(Sitting up)

Goodness, this really is the life of an athlete.

(All four athletes wake up.)

(The oldest, who is also the most diligent, )

(makes her bed neatly like a soldier.)

(She finishes getting ready in an instant.)

You look like you're in the Marine Corps.

- Right? - It suits you.

(She even dresses like a marine.)

(I'll get ready quickly too!)

- Do you want me to braid your hair? - Yes, please.

(Mother Jin braids Childish Park's hair skillfully.)

(Smiling)

Is it supposed to feel like my hair is being pulled out?

Yes, it is. And you're going to swim.

I... No.

(Mom...)

(My hair is about to be ripped off.)

(Endure it.)

(With Mother Jin's rather rough handling, )

(her hair is made.)

How do you like it?

- It's nice, thank you. - No problem.

(The athletes prepare quickly and get ready in 20 minutes.)

We're all ready.

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

- It's a nice weather. It's so nice. - Yes.

(They head to the 1st training spot of the 2nd day in Jeju Island!)

The clouds are incredible.

The clouds are so pretty.

What a pretty sky.

(Jeju Island's bright morning is perfect for training.)

There's a runner.

(Turning their heads)

- That man over there? - Where?

He runs so lightly.

He must be warming up.

- His posture... - He has great posture.

His posture... The cadence of 180.

(Laughing)

His pace should be seven or so.

He's not that fast.

- We can see and judge them now. - The pace...

Well, yes.

(Feeling proud)

We must be almost there.

There are swimsuits all around.

It's Panpo Port.

I hear the water level is low now.

You're right. He went in there,

- but the water reaches half of him. - You're right.

We look like sea lifeguards.

(Amazed)

- People will think we're experts. - I agree.

Our postures are.

(Sports is about spirit.)

We look like four trainers.

Yes. We're very confident.

It's the sea.

I smell the sea.

The water is calm.

It's pretty.

What do you call the sparkling of the water?

- Sun glitter. - Sun glitter.

(The Jeju sea glitters from the morning sun.)

- My gosh. - How pretty.

(Instructor mode)

- It's nice. - Come quickly.

Hello, sir.

- One, two. - We don't have much time.

One, two.

I'm joking.

- We... - We'll go when you tell us to.

- We are runners. - How are you feeling?

- Good. - Good.

Anyway, today, we'll give it a go...

at the first open water swimming.

(Now, it's sea swimming training like the real deal!)

(They leave the swimming pool...)

(and swim across the rough sea.)

(The first outdoor swimming, open water swimming training)

(Excited and nervous)

(Sighing)

(And here is one person who is a lot more worried.)

When you think of swimming in the sea, it makes you scared.

But this is the safest open water in Jeju Island.

- It's really great. - It was hard to secure this spot.

It's almost like an indoor swimming pool.

(Panpo Port is as calm as a swimming pool.)

You can see what is under the water.

(The water is clean and clear that you can see the seabed.)

The water isn't that deep either.

- Is that so? - This place...

Had I known about this place when I was an active athlete,

I would've trained here often.

- It's that... - Is it that good?

It's basically a swimming pool made by nature.

- You're right. - It's just like a swimming pool.

It's like a mat.

So don't worry and relax when you swim here.

Don't get scared. Think of this as a swimming pool.

I'll teach you how to wear a wetsuit.

If you don't wear a wetsuit properly,

it will get stuck on your shoulder.

And this will hinder you from rotating your shoulders.

You must wear it right.

Actually, athletes prefer to wear this in water.

When you wear it in water,

the water helps the suit to go to the right place.

We'll start with wearing the wetsuits...

and continue to learn technical stuff.

Then we'll finish the training.

- Okay. - Okay.

- Let's go. - Okay.

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

(Basic open water training, wearing wetsuits)

The water is so clear today.

- It's amazing. - It's so clear.

Here.

(They prepare to enter the water and put on the wetsuits.)

(He throws in the wetsuit first.)

- That's cool. - Goodness.

(Coach Heo jumps in too.)

- Goodness. - My gosh.

(She is a copycat.)

(She throws it in.)

Can I go now?

- Here I go. - She jumped in.

The water is so clear.

Gosh, it's so cool.

The water is cold.

I assume it isn't hot.

(She is worried about getting into the water.)

(She approaches the ladder.)

Really.

(Cautious)

It's cold.

Show us a different side of you from yesterday.

Still, wasn't I cool yesterday?

Yes, you were.

(She climbs down slowly.)

In the swimming pool...

(Despite her worries, her feet touch the seabed.)

(Yes, this is fine!)

(Next, Uie...)

(and In Ah enter the water too.)

Now, I'll teach you how to put this on in the water.

- Okay. - Look.

Straighten out your wetsuit.

Don't flip it. The front should be on top.

Then...

When you fold it in half, you'll see this space.

- Yes. - As if you put on pants.

Put water in here.

- That's when you put your foot in. - Okay.

After you put your foot in, shake your foot.

- Okay. - Like a fish flapping.

(A rather boisterous way of putting on a wetsuit)

- Then it goes in smoothly, right? - Yes.

- Nice. - Right?

- No way! - It goes in, right?

See? It goes in.

- Isn't it fascinating? - Yes.

Shake it like a fish again.

(Boisterous Min Ho)

Shake it like a fish again.

- This is so easy. - Shake it.

- It goes in, right? - Goodness!

- Isn't it fascinating? - Yes.

I feel proud.

(It's fun teaching you guys!)

- But when I watched YouTube videos, - How does this...

they put on the wetsuit in a really cool way.

- Yes. They didn't flap like fish. - They didn't put it on like this.

Well, that's...

They may look cook, but it's not accurate.

This is the most accurate way.

Athletes prefer this way, actually.

Shaking.

Are you done putting on the lower half?

Now, your arms. Do you see the arm hole?

Put water in here now.

(The same goes for the arms as they did with the legs.)

Now, reach out your fingers as far as possible...

and flap like fish again.

(Shake them like fish again!)

(Flapping)

Then you can put it on.

- Doesn't it go in smoothly? - Goodness.

The same goes for the other side.

(The suit goes in smoothly when they put it on in the water.)

- This is exciting. - You're done now. Put your arm up.

You're not finished.

- This is the last step. - It's very important.

- Pull this down to your shoulders. - This is very important.

Your shoulders will feel a lot more comfortable now.

- My goodness. - Your shoulders feel comfortable.

(Before pulling down the sleeve, )

(there was a lot of space left.)

(After pulling down the sleeve, )

(it became tight like this.)

- Goodness. - It feels different now.

- It's different, right? - It's very comfortable that way.

- Goodness. - This part feels very comfortable.

This is impossible.

(They never felt this comfortable in wetsuits before.)

- Already... - My goodness.

- This affects your swimming a lot. - For real.

Does it fit you perfectly?

- It fell into the right places. - My arms are so free to move.

Now that I wear it properly.

- Are you comfortable in your suits? - Yes.

Now, I'll teach you about looking forward.

(Basic open water training, looking forward)

What I mean by looking forward is,

in a swimming pool, there are lines.

So even without looking up, you can see where you're going...

- and check your location. - Yes.

(You can check your location without looking up.)

But you can't do that in open water swimming.

You must look forward and figure out which direction you are going.

Looking forward is a must.

The water here is clear.

- The water level is low too. - Yes.

But it's not like that in the Tongyeong competition.

As soon as you swim beyond the first 10m or 20m,

you can't see anything.

It feels like you're swimming with your eyes closed.

The water is pitch black.

- Tongyeong is? - Tongyeong is.

So you must look forward.

- So... - It doesn't sound easy.

I'll stand in front there.

Swim until there with the breathing...

but with your eyes closed.

- What? - Swim with your eyes closed.

(How can we do that?)

Imagine you're in Tongyeong. Close your eyes...

and swim to me.

(A camera for filming)

(Surprised)

(Coach Heo bites the camera with his teeth...)

(and do backstrokes to go to his position.)

(The national athlete looks cool when doing just about anything.)

Promise to close your eyes and swim.

- Okay. - Don't open your eyes.

Okay.

- Close my eyes? - Close tight.

How would we do that?

(Iron Girls' official mermaid, Uie tries first.)

Okay. Go, Uie.

Go, Uie.

She is so different from when she cycled yesterday.

- Ready. - Here comes the fish.

- Close your eyes. Go. - Let's go.

(The finishing point)

- You're cool. - Goodness.

- You're cool. - Goodness.

(She swims forward without hesitation.)

She sure is different.

She sure is different.

- She is swimming in the right way. - She is doing well.

(She swims straight at a scarily fast pace!)

Close your eyes!

(The finishing point)

(She is heading exactly to the goal.)

Close your eyes!

(She goes slightly to the left.)

She still goes slightly to the left.

Just a bit.

She is good.

(It's good considering that she had her eyes closed!)

Well done. Stop.

I was so scared.

She is a born swimmer.

- Did I get to the right place? - You did.

When you close your eyes,

it's a bit scary. I felt scared too.

- I agree, since you can't see. - But you swam so accurately.

- How do you do that? - Go, In Ah.

(Who is the next swimmer?)

Go, In Ah.

Go, In Ah.

- Close your eyes. - Iron In Ah.

- It's Iron In Ah. - Okay.

- Go. - Go!

(Go!)

Go!

(The finishing point)

- She's going well. - I want to do that too.

Did they really close their eyes?

(She swims across the sea coolly.)

(Iron In Ah swims so straight that the coach gets suspicious.)

See? She is going that way.

You end up going that way.

(But she diverges as she swims.)

She is good.

Okay.

(She swerved to the right, but it was still fine.)

Okay.

(Stop swimming.)

Okay.

- You're such a good swimmer. - You went so well.

Did I swim to the right spot?

- No, a bit to the right. Oh, left. - You went a bit to the left.

Iron In Ah, you're a good swimmer.

(Grinning)

(Next is Ju Hyun who keeps improving.)

Ready.

- Go! - Go.

You can do it.

- Go. - You can do it.

(She can swim freestyle well even in the sea now.)

(Look at me...)

(swimming with ease.)

You're moving to the right.

(What?)

(Look at me...)

(swimming with ease.)

You're moving to the right.

(What?)

She swims well with her eyes closed.

(She seemed to be going well, )

(but she suddenly gets off course.)

(Hello?)

You're moving to the right.

Where is she going?

(How far are you going?)

- Stop her. - Hey!

- This isn't the right place. - She went that far.

- Coach. - Now...

You swam less than 25m, but you went that far off course.

It means you swerved a lot.

In a competition, we swim 1,500m.

It's only 1,500m if you strictly stick...

to the buoy set up by the association.

The question is, who will make that round the fastest?

If you swim like Ju Hyun, how long of a distance...

do you end up swimming 1.5km?

She might end up swimming 3.9km.

(Laughing)

He said 3.9km.

(Meanwhile, she cannot smile.)

(The first sea swimming...)

(isn't easy for Seo Yeon.)

Okay.

(Can she do it?)

Ready. Close your eyes.

Just swim slowly. Go.

(She carefully lets herself float on the sea.)

She started off in the wrong direction.

Goodness!

Goodness!

- What is it? - I'm scared.

You're scared.

(It feels even more difficult with her eyes closed.)

- You're very scared. - Seo Yeon, if it's too scary,

just kick using your feet. Don't use your arms.

(She takes a deep breath...)

(and sets off again.)

She is swimming toward the right.

- She is swimming toward the right. - You're right.

Still, she's good.

- She's good. - Seo Yeon is swimming well!

(Seo Yeon swims hard just like how she learned.)

(She is swimming in the sea! I'm so proud of her.)

(Seo Yeon is swimming well!)

(But she is way off course.)

- Okay. - Seo Yeon, good job.

- You made it here. - It's difficult, isn't it?

(She started off to her left.)

(The finishing point)

(She's completely gone off course.)

Good job.

- But I came here all the way? - Yes.

- You did very well! - But you were quite swept away.

- But it's still very good. - You were very fast.

- Really? - Yes, you were.

I can't believe it!

If you have difficulty looking forward,

you may even swim 1.7km to 1.8km,

not 1.5km.

(To have a good record, looking forward is very important.)

I'll now explain how you can look forward.

(How to look forward in the open water swimming)

- When we usually swim, - Yes?

- we don't raise our heads. - That's right.

(We don't raise our heads.)

Just breathe briefly and see ahead only as your eyes are out of water.

(Raise your head just until your eyes can see ahead.)

You shouldn't raise your whole face. If you do that...

(If you raise your head, your upper body will sink too.)

Your upper body will easily sink. So, only your eyes.

Breathe once, and then look forward.

(Breathe and raise your head only until your eyes can see ahead.)

This is how it goes. I'll show you again.

(The correct way of looking forward while swimming)

(He looks forward.)

I got it.

(The correct way of looking forward while swimming)

Like that.

- I got it. - Now I see how to do it.

It looks as if he's sneaking in the water.

- He's amazing. - He swam that far in just a second.

- Did you see how to do this? - Yes, we did.

- I got it. - Breathe once...

But you don't need to do this all the time.

Breathe a few times and then, look ahead.

That'll do.

If you keep checking ahead, it will drain your energy.

So just once as you breathe will be enough.

Then, I'll swim until I reach Captain Kim.

- Okay. - And I'll turn and come back here.

- Good. - Yes.

- I'm coming! - Yes.

(Min Ho, the finishing point)

He's so fast!

(He dashes to the point without getting off course!)

(After checking the exact path, )

(he swims hard and fast.)

(He succeeds in turning at the point without any mistakes.)

(Astonished)

Only his eyes got out of the water.

He did exactly how he instructed us.

(Everyone watches a former national athlete's professional swimming.)

His eyes are out now.

(Coach Heo comes back very fast.)

- He's amazing. - That's Coach Heo!

(I'm back.)

(Smoothly)

- He's amazing. - My heart skipped a beat.

- Our hearts raced! - We're impressed!

(Heart Racing Girls)

But should we do that fast too?

No, I just went fast to look cool.

- I feel so tired now! - I knew it!

- Shall we try it now? - Yes.

This step is essential.

You get to Captain Kim and come back here.

(That's the halfway point.)

- Let's go! - She starts now.

(Uie the Mermaid starts first.)

- Start! - Go!

(Will she manage to look forward while reaching the point?)

Start now!

(She starts.)

Oh, my.

She's fast.

(Looking forward)

(She breathes once...)

(and looks forward.)

(Uie heads to the point swimming straight.)

(And then...)

(she spots her target!)

(A great example of looking forward)

She's doing well.

(The finishing point)

(Without getting off course, )

(she arrives at the point.)

She's doing well. She already has some skills.

(What's next?)

- She turns perfectly. - Nice!

- How did she do that? - Her speed is the same.

Oh, my.

(Once she checks the arrival point, she turns perfectly.)

Some fail even after looking forward,

but she did it perfectly.

How can she turn that easily?

She never stops!

(She doesn't forget to check forward.)

(Are you sure you've never done this before, Uie?)

Only her eyes are out!

- Only her eyes are out! - She almost made it.

- Good job! - You did very well, Uie!

- Okay! - You're so cool, Uie!

(She succeeded in finishing a round track.)

- You're great! - Nice job!

- Awesome! - You made it!

(Their hearts raced twice today.)

- You do so well. - My heart skipped a beat.

But it was still hard,

- as I wasn't used to the technique. - Indeed.

But the more you raise your head, the harder it gets.

So, when we see real pros swimming,

we can't tell whether they look forward or not.

That's their level.

Others don't need to turn. Just stand up there and come back.

- Without making a turn. - You can do it slowly.

(Next up is Iron In Ah.)

(Will she be able to look forward while swimming?)

(Start)

- She does that! - She does.

- She does that! - She does.

That's it!

Okay!

(Looking forward)

(Looking forward)

(She got the hang of the technique as soon as she learned it.)

(Looking forward)

She does well.

Everyone does pretty well today.

(Why do all of you do so well today?)

Oh, my.

(She arrives at the target point without any mistakes.)

- Okay! - She does well.

(The finishing point)

She follows the exact path!

(She swims in a straight line.)

Okay!

(She correctly arrives at the finishing point.)

(Before and after learning the technique)

- She does so well! - She followed the shortest cut!

She swims so well as if she's learned for a long.

- She's done well. - She's been good for a long.

- She's been doing all along? - Just give her some attention.

- You've been doing all along? - I just like swimming.

She does well. She might be good from the start!

- Why are you interviewing her? - That's what I mean.

Now you should swim back.

- Come to Mommy! - Check the way and follow it.

- To here. - Come over here!

(She starts heading to the starting point.)

(In Ah)

She now knows how to look forward.

- She now knows it. - Nice!

(She can now look forward at ease.)

- Forward! - Look at her.

She took the exact path!

- She did it. - You did it, In Ah!

(Well done, In Ah!)

- Nice! - Great.

- You did so well. - Good job!

(She can now swim easily in open water.)

I'm very surprised.

- Thank you. - That's it.

You did so well, seriously.

Especially the technique after moving your right arm.

- I did as you instructed me. - You got what I taught you.

I'm glad to hear that.

You're so good at it now.

- Shall we start now? - Yes.

- Ju Hyun, let's go! - I may need a buoy on my body.

You can do it. Take it slow.

- Start! - Let's go!

(Will Ju Hyun, the novice swimmer, be able to look forward?)

(She did it!)

(Oh, my!)

(Looking ahead once)

- You can do it! - You don't need to do it all along.

(Ju Hyun also swims as she's taught.)

(The finishing point)

You're doing so well!

(She powerfully dashes to the goal one stroke at a time.)

- She got there without mistakes! - She did well!

- It's like you were always good. - Really?

(Everyone gives applause.)

- Ju Hyun, good job! - She took the exact path!

(The finishing point)

(She exactly got to the finishing point!)

(Before and after learning the technique)

- Ju Hyun, nicely done! - Good job!

You did a great job.

- It's like you were always good. - My chest suddenly hurts.

- The suit is too tight? - Yes, maybe.

(She still feels uncomfortable with the wetsuit on.)

She feels tight.

- Why? - I will move up to you for a while.

She feels uncomfortable with it.

She may need to buy a bigger one.

(Breathing out)

She feels tight. What's wrong?

She feels tight. What's wrong?

(He's now a human buoy.)

- Didn't she grab him by his throat? - No.

(Didn't she grab him by his throat?)

- He's her dad now. - Yes, her dad.

- Okay. - You may need to buy a bigger suit.

I mean, a bigger one.

Please come over here, following the right path!

(Now is the time to go back!)

Move your feet!

(Now is the time to go back!)

She's very fast!

- You're doing well! - She did it!

- Nice! - Nice!

(Ju Hyun takes a breath and looks forward in turn.)

She's following the exact path!

(Ju Hyun)

- She's very cute! - Nice!

(She successfully arrives...)

(at the finishing point.)

(Now it's time she grabs her friendly uncle by his collar.)

(She's so cute.)

Slowly.

- You should hold me. - We will. Don't worry.

I'll also swim next to her.

- Follow me. - Okay.

(Let's go, Seo Yeon!)

- I start now. - Yes!

(Will she manage to look forward while swimming in the sea?)

- Go slowly. Move when you're ready. - Move slowly.

- Imagine you're paddling. - Okay.

(She starts.)

(First, she takes a breath...)

(and now starts looking forward!)

It seems like she's looking forward.

She swam until there!

(She seems to be looking forward!)

(During her first open water swimming, )

(she successfully looked forward.)

(Seo Yeon)

(She correctly arrives at the target point.)

You saw the target point, right?

Yes.

She saw it twice.

- It's amazing. - She saw it twice.

- She saw it twice. - She made it.

Seo Yeon's swimming is still...

- in its infancy. - Yes.

It's not easy to look forward at her level.

- I know. - It's difficult.

(Just attempting to look forward is a big achievement.)

It's amazing that she went all the way there.

She did well keeping her eyes forward.

(Before and after learning the technique)

(You're the best.)

(Everyone successfully completed their training of looking forward.)

Today, we learned to look forward while swimming.

- Yes. - In fact,

it's a done deal once you learn to look forward.

It would be nice to learn more in detail like the athletes,

but for us, it's important to finish the race.

- Right. - So today,

let's swim as much as we can.

- Yes. - As much as you can.

- In open water. - Yes.

Why?

Because we need to swim 1.5km.

- Yes. - To do that,

we need to train accordingly.

- Yes. - So today,

you will swim as much as you can.

(Advanced open water training in real conditions)

(What is the swimming course like?)

It's 150m straight ahead.

(A 150m straight course)

If you return, it's 300m.

(A round trip makes one lap 300m.)

(To put it in perspective, )

(the pool where they usually train in is 25m.)

(It would take 6 pools to match the current 150m course.)

(A round trip makes one lap 300m.)

(From here...)

(to here)

For example, if you swim five laps,

- it makes 1.5km. - Yes.

So here's what I think. Even if you get tired,

don't just give up.

Try to swim until your limits.

Set a goal where you won't be embarrassed.

Swim as much as you can...

and go home without being embarrassed.

- Then we go home? - It's because...

we can't train in open water often.

Yes.

We came to Jeju Island...

- for the open water training. - You're right.

- So... - Okay.

Honestly, state your target distance.

- And... Yes. - For me,

it's a miracle to swim all the way from here to there.

Yes.

(Seo Yeon's target distance during her last training...)

(was 150m.)

(But her final record...)

(was 75m, not 150m.)

It's a miracle to swim all the way from here to there.

- Yes. - I'll try 150m.

Yours is 150m? Okay.

Okay.

- It's your first try. - Yes.

- It's my first 150m. - Okay.

And Iron In Ah.

Me? I have no idea how far this is.

(In Ah's last target distance...)

(was 400m.)

- So 300m? - Making a round trip is 300m.

How many laps do you want to try?

(Thinking hard)

How many laps?

I'll try swimming three laps.

- Go! - Yes.

- It's my first try. - Okay. Three laps.

- Uie... - How many laps, Uie?

(And our ace)

- How many laps? - You're a good swimmer.

Then...

(She already swam 875m last time.)

You need to swim at least 1,500m.

Exactly.

(That's the swimming course of the triathlon.)

- To prepare for the triathlon. - I'll try five laps.

(Uie is trying to swim 1,500m.)

(Our ace is amazing.)

Then we will...

check your records just in case.

For Ju Hyun, I think...

Your face turned very pale.

- Yes. - Yes.

Your face turned very pale.

- Yes. - Yes.

Your lips are too white. Maybe you can't swim anymore.

- It's so pale. - Watch me carefully.

(Ju Hyun was excited like a child.)

(It's so cool!)

(I love the water!)

(I love the ocean!)

(Her condition suddenly got worse.)

(My chest feels very tight.)

(She's struggling to adapt to the suit and feels uncomfortable.)

(In fact)

It feels very tight wearing this outside of water.

If I need to swim in this...

(Ju Hyun found the wetsuit uncomfortable from the start.)

Wearing a wetsuit can be difficult.

Wearing a wetsuit,

I felt so tight. It was really hard.

I don't think I can put up with the tight feeling.

I don't like wearing turtlenecks too.

(For Ju Hyon who doesn't like the tightness, )

(wearing a wetsuit was difficult.)

(She comes out of the water...)

(and takes a break without the wetsuit.)

- She became so pale. - It's because of the suit.

Let's go out.

- Shall I? For a while? - Yes.

Can you go up alone? Let me help.

(She decides to take a break.)

(The wetsuit is an unexpected challenge.)

(Worried)

Ju Hyun will be fine without the suit.

(She's frustrated as she can't swim as she likes.)

- Ju Hyun... - Yes.

Still feels uncomfortable.

- Oh, no. - Since safety comes first,

she'll take a break and join us back at 1pm.

- We'll continue without her. - Okay.

You can see the red thing there.

Keep your eyes on that while swimming like we trained.

- Okay. - But...

- some athletes have poor vision. - Yes.

They can identify the buoy from the ground...

and swim looking at the buildings behind it.

- Oh, okay. - For example, now...

you can see the white canopy.

- Yes. - Something like a tent.

- Yes. - You can swim looking at that.

All right.

Swim as much as you can, but don't push yourself too hard.

- Okay. - Coach Heo,

- please take care of Seo Yeon. - Yes.

Oh, no.

Let's do this!

- We can do it! - Let's go, Iron Girls!

This is a training session.

This is an in-depth training session.

Killing training will be difficult.

- Where's Uie? - Let's do this properly.

- Let's finish the killing training. - Okay.

- Iron Girls! - Iron Girls!

Let's go! Start.

(Start)

(The two start swimming at great speed.)

(In Ah and Uie)

(They need to swim a long distance.)

(Uie and In Ah)

(Calmly increasing the pace)

Very good.

(They're swimming alongside like twins.)

The red buoy.

Very good.

(She looks forward as she trained.)

Slowly relax and release the tension.

Good.

(She learns so fast.)

(Energizer Bunny follows Uie.)

(She looks forward right away.)

(In Ah's goal: Looking forward)

(In Ah's swimming posture improved a lot.)

(Her upper body doesn't lift much while breathing in.)

(Her kicks are soft.)

(She applies everything she learned to the open water swimming.)

(Uie and In Ah)

(In Ah became semi-ace after one month of training.)

(She's swimming at a similar pace as Uie.)

(Uie and In Ah)

(They're halfway until the turning point.)

(In Ah closely chases Uie, who's leading.)

(Uie and In Ah)

(Uie increases her speed after checking the buoy.)

(Uie and In Ah)

(Uie speeds up.)

(I'm the ace of swimming.)

(Ace Uie arrived at the turning point in no time.)

(Uie finished swimming 150m.)

(She continues swimming without taking a break.)

(Right behind her, )

(In Ah arrives at the turning point.)

(She continues swimming without taking a break as well.)

(Ace Uie, who's having fun in the water...)

(awakens her speeding instincts.)

(Uie and In Ah)

(She is swimming in the lead at great speed.)

(In Ah is keeping up her pace.)

- One lap! - My goodness.

(Uie finishes 300m in 4 minutes.)

Aren't you tired? One lap!

(She doesn't take a break again!)

(Successfully adapted to the wetsuit and open water swimming)

(This is truly the essence of being one with the water.)

(In Ah finishes 300m in 5 minutes and 10 seconds.)

(She continues keeping her own pace.)

(Proficient even though it's their first open water swimming)

(Successfully looking forward)

(Successfully adapted to open water swimming)

(While In Ah is focusing on swimming, )

(Uie is already near the turning point again.)

(How about Seo Yeon?)

(She's wearing a buoy for safety.)

(Together with Coach Heo, )

You're doing great.

(she swims calmly.)

Slowly and release the tension. Okay.

You're doing great. Good.

(She stops suddenly.)

(Seo Yeon looks a bit anxious.)

Good.

(Taking a moment to catch her breath while swimming on her back)

Let's go again.

(She tries to continue.)

(But she's unable to continue.)

Slowly and release the tension.

(The reason she's scared)

(When she arrived here...)

It's cold!

(The water was shallow enough to see four rungs of the ladder.)

(As time passed, the water level increased.)

I think the water is getting deeper.

(Together with the increased water level...)

- It's getting deeper. - Oh, no. Someone should hold me.

Don't worry. I'll hold you.

(Now that the water has deepened, )

(her feet no longer touch the ground.)

Slowly and release the tension. Okay.

(Seo Yeon froze in the same spot.)

Don't press down the water.

Swim as if you're moving forward.

(She calmly breathes in.)

(Seo Yeon tries swimming again.)

(She seems fine...)

(but her body sinks again.)

(She stops after swimming for a while.)

Why am I so out of breath?

- You have too much tension. - Right.

Your body will float.

(Her pace is ruined.)

Try to see the ground.

Don't look forward. Look at the ground.

Don't lift your upper body too much.

(Overcoming aquaphobia)

(To swim looking at the ground so that the upper body doesn't lift)

You're already halfway there.

- Already? - Yes.

I can do this.

(She pulls herself together.)

- I'm almost there. - You're almost there!

You're almost there.

Shall we swim until there?

- Can you do it? - I'll try.

Okay.

(After a deep breath, she sets off again.)

(As per Coach Heo's advice, she keeps her eyes on the ground.)

(Her upper body still lifts up a lot when she breathes in, )

(but she keeps her eyes on the ground as much as she can.)

(With the determination to swim all the way, )

(she speeds up for the last time.)

(Seo Yeon is getting stable again.)

(To swim looking at the ground so that the upper body doesn't lift)

You're almost there.

(To swim looking at the ground so that the upper body doesn't lift)

(Seo Yeon finished swimming 150m.)

You finished.

You swam so much.

- Isn't this your farthest distance? - Yes.

(To Seo Yeon, it wouldn't have been easy.)

(Her limit was only 75m not long ago.)

Your current rhythm is good.

(She repeatedly paused in the middle in fear, )

(but in the end, Seo Yeon finished swimming 150m.)

- I'll walk back. - Okay.

(The novice swimmer is improving step by step.)

(On the other hand, Uie...)

Two laps.

(She finished 2 laps in 8 minutes and 30 seconds.)

(Uie is at 600m of 1,500m.)

(Relaxed)

(Uie the Mermaid is enjoying the open water.)

(Her swimming is perfect for the triathlon.)

(She arrives at the turning point for the third time.)

(Uie is at 750m of 1,500m.)

(In an instant, she surpasses half of the target distance.)

(I prefer swimming to taking breaks.)

(Uie's truly enjoying the open sea.)

(The more she swims, )

(the better her facial expression becomes.)

(Uie is at 900m of 1,500m.)

(Uie)

(She heads to the turning point again.)

(In Ah just reached the turning point.)

(In Ah is at 450m of 900m.)

(She's halfway there too!)

(She maintains her pace without getting tired as well.)

(In Ah's swimming skills are truly amazing.)

(She is setting a new personal record.)

(She's about to finish her second lap.)

(In Ah is at 600m of 900m.)

(But...)

(In Ah hurriedly comes out of the water.)

(She still has 300m left.)

- Do you want to sit? - I want to take the suit off.

- Do you want it off? - Okay.

(Is she going to stop swimming?)

(Just now, when she reached 300m, )

(In Ah stopped looking uncomfortable.)

I don't think I can wear the wetsuit.

(The problem was the wetsuit.)

- I'm not tired. - How are you?

This is too tight.

(Getting used to the wetsuit is more of an issue than her stamina.)

(She endures and continues.)

(But the wetsuit kept making her pause.)

(In Ah takes off the wetsuit.)

(Is she continuing to swim right away?)

(It was the wetsuit that was uncomfortable. She's not giving up!)

(Her body is lighter so her swimming is now faster.)

(That means...)

(Checking her front)

(Her pace speeds up.)

(In Ah)

(Mermaid)

(She quickly arrives at her last turning point.)

(She departs for her last 150m.)

(In Ah is at 750m of 900m.)

(She doesn't look tired.)

(But she's swimming around 1km.)

(Her posture is stable until the end.)

(She arrives as the first trainee to complete swimming.)

Give her an applause!

(In Ah's goal: 900m)

(Success)

- My gosh, In Ah. - It was 900m!

Can you swim more?

I think you can.

- Did she make it? - She swam 900m.

You must be tired.

You're amazing.

You'll definitely finish the triathlon.

- You'll finish. - Right?

You look like you swam before.

I swam with my grandmother at the social welfare center.

(When she was an elementary student)

You're amazing. What's your record?

- It was 20 minutes. - Was it 20 minutes?

Then it would be 40 minutes. It's good.

- Would it be 40 minutes? - Yes, it adds up to 40 minutes.

It's fine.

The seawater was smelly so I don't feel like drinking water.

Despite these variables, it was good that you came.

During the last triathlon,

it was ten times worse than this.

I don't like it. I'm not used to the seawater.

- Right. Your lips get salty. - Yes.

It's because you go in and out.

- I lose my focus. - Let's go.

Are you swimming again?

Are you swimming again?

I want to try one more time.

She has a strong competitive spirit.

(Seo Yeon finished 150m just now.)

They're so good.

They're like seals.

(She's amazed at Uie and In Ah.)

Is she swimming 1.5km?

(She's full of envy.)

Shall I swim again?

(She asks to try once more time.)

I'll try without the buoy.

I should be able to swim right after stopping in the middle.

Yes. Okay.

(She gets rid of the buoy that she held on to.)

(She starts swimming.)

(She achieved her goal, )

(but she asked for an extra session with her fiery passion.)

(I'll reach the end alone.)

(Even though she stops in the middle, )

(she takes a deep breath, )

(and swims again.)

(Her gaze is stable and focused.)

(Seo Yeon is slowly getting a grip.)

(Her passion never runs out.)

(Seo Yeon is already near the turning point.)

(Her posture isn't perfect.)

(But she completes swimming an extra 150m without a buoy.)

(Seo Yeon's final record: 300m)

Good job.

Breathe out the air in your stomach.

(She overcame her fear and took on challenges for this.)

(Meanwhile)

Are you okay now?

I'll try putting on the wetsuit up here.

(Ju Hyun is a bit recovered and tries putting on the wetsuit again.)

Okay.

(At that time, Uie is swimming her last 150m.)

(Uie is at 1,250m of 1,500m.)

She's like a seal.

(Uie is at 1,250m of 1,500m.)

(She's been swimming over 1,000m without a break.)

(Uie is moving forward in an exactly straight line.)

- That's awesome! - She's unbelievable.

What is she doing? Has she finished one event of a triathlon?

Right, if she finished that.

(Just before completing 1,500m!)

She'd set a record this time.

Apart from the record, she might be the top among the club.

I guess so.

(She might be ranked in the top range.)

(She's already an iron girl in swimming.)

(Here she comes.)

(Our best swimmer!)

(She keeps her posture and speed steady to the end.)

Here she comes.

(Uie completed 1,500m.)

But,

the distance...

isn't enough.

(The distance isn't enough?)

Here, it says...

it's not 1,500m yet.

I'll swim a bit more.

(What's with her?)

The watch you wear under the water...

loses connection to the GPS, so it detects less distance.

She definitely swam over 1,500m.

(Uie leaves to get the lost distance back.)

- Let her do it. - She can swim 3km more.

She still has some energy left.

(Uie)

(The best swimmer with infinite stamina)

(She completed 1,500m already.)

(Uie doesn't get tired after swimming back and forth.)

(Incredible cardiovascular endurance)

With that cardiovascular endurance, she can do any sports.

(Uie reaches 1,650m.)

(I'm still hungry for the record!)

She looks so beautiful when she swims.

(Especially shining when swimming)

(Definitely the ace, Uie)

(She made one more lap than her original goal.)

(Uie's record: 1,800m)

Are you done?

I could have done it faster.

It's 1,520m.

(The smartwatch says she completed 1,500m!)

(Amazed)

- She's good. - But,

I'm worried about two things after the open water swimming.

(A sudden briefing session on the open water swimming)

Since I can't see the buoys,

- I can't tell where I'm heading to. - Right.

The second thing is,

the water is salty, and I thought I could adjust, but I can't at all.

We need to practice for that first. It's not about a record.

(The sea water tastes so salty, and she can't adjust to it.)

(Analysis comes first to her, rather than enjoying the finish.)

I feel sorry.

(A true mindset of a pro athlete who cares about the record)

- I feel very sorry. - Don't you feel tired?

- What? - Don't you feel tired?

No.

- You look really happy. - I feel so bad.

- About the time? - Yes.

Come on.

(Advanced open water training)

(Uie 1,800m, In Ah 900m, Seo Yeon 300m)

(Ju Hyun tries again.)

- Are you going to do it? - Yes.

How far are you going to go?

I'll make one lap.

- You'll go and come back? - Yes.

(She still looks uncomfortable in the wetsuit.)

- Can Ju Hyun swim again? - I think she'd be all right.

(Worried)

I'll make it today, no matter what.

Bend your back.

(We've come here for training, and I won't leave like this!)

(But the wetsuit is the problem.)

(After taking a deep breath)

(Ju Hyun's goal: 300m)

(Although she hasn't recovered completely yet, )

(she swims with an iron will.)

(Ju Hyun)

(It's quite far.)

(Is she able to finish it?)

Look ahead from time to time.

(Keeping her eyes forward, )

(Ju Hyun trains seriously.)

Ju Hyun is fast too.

(Ju Hyun trains seriously.)

(Although the wetsuit makes her breathing uncomfortable, )

(she endures it...)

(and reaches the 150m turning point.)

That's so nice.

(She endures it and reaches the 150m turning point.)

(She keeps feeling tight in the chest.)

(Still, she doesn't give up.)

Try moving more lightly.

(Ju Hyunis at 150m of 300m.)

(She has 150m left to go.)

I'll make it today, no matter what.

(I'm Park Ju Hyun who has a dogged spirit.)

(I'll make it today, no matter what.)

(When her posture collapses, )

(Coach Heo assists her.)

Put your arms closer. The other arm moves now. Right.

(With the solid help from the coach...)

(and her grit to complete what she started, )

(she moves forward without stopping.)

(I can do this.)

(She comes back without stopping.)

You did a good job.

You made it.

(Ju Hyun's goal: 300m)

(Success)

- You did it! - Good job.

(Are you all right?)

(She endured the wetsuit and completed the course.)

(Ju Hyun's final record: 300m)

(The result of open water training: Uie 1,800m, In Ah 900m, )

(Seo Yeon 300m, Ju Hyun 300m)

(The final review on the open water training)

You know,

you're so good at running,

and your mental and physical strength is great.

But if you can't swim, you can't show what you got.

- It's important to swim every day. - Okay.

And as I see,

considering we haven't trained for a long time,

Seo Yeon swimming in the sea...

is something incredible. You did a wonderful job.

You think you're overbreathing when you swim,

but I think...

you should rather recognize it as something natural.

The moment you wonder if it's wrong,

- you stop. - That's true.

So, I think, when you swim,

when you overbreathe, don't stop.

You set your goal, such as ten strokes.

- Do 10 strokes and then stop. - Do it 10 times.

- Then you get to endure it. - I see.

And In Ah, you're a good swimmer.

- Isn't she amazing? - I saw her from the back. So good.

The waves disturbed me more than I thought.

There are twigs, and it smells.

Right, the smell.

So I think it was a good idea to try it at Jeju Island today.

What was your record exactly, Uie?

It says it took 36 seconds,

no, 36 minutes.

I followed Uie when she was swimming.

- Her pace was never 36 minutes. - I know.

(To check Uie's pace...)

(Min Ho, Uie)

(Coach Heo followed her.)

I think it's around mid-20 minutes.

- My goodness. - That's what I'm saying.

- It'd be 25 to 26 minutes. - Right.

I can tell if I follow her.

(Our ace, as expected)

So this is my evaluation.

She can rank first in swimming among female triathlon club members.

(The first in swimming among female triathlon club members)

But she needs to try harder than what she did today.

She needs more training...

and she needs to be more ambitious.

Now, it feels awkward to see buoys,

and I went to the right as I looked down while swimming.

Right, it was your first day.

You can't help it.

Ju Hyun, I thought you gave up earlier,

but you made a lap.

It took 8 minutes and 7 seconds for Ju Hyun to make a lap.

That's not a cutoff.

- It's not a cutoff. - It isn't.

This is what I need to endure.

I'll go on with my war against the wetsuit.

- Right. - You can do it.

- You should sleep in it. - Some athletes do that.

Really?

Some national team members find it hard...

- to get accustomed to it. - National athletes do that?

- It's that hard. - Then,

since the weather is hot now,

starting in late September, I'll be in the wetsuit all day.

You can wear it for all your schedules.

You can wear it in hanbok filming a historical drama.

You can wear it when you film a drama.

- So this is my main job, I guess. - Yes, it is now.

- My main job is being an athlete. - Yes.

We came to Jeju Island,

and it paid off, I think.

As your captain, I'm satisfied.

- What comes after killing training? - Healing!

Let's go for healing training now.

- Let's go! - We should do the chant.

In 1, 2, 3.

- Iron Girls! - Iron Girls!

- Let's go. - You did a good job.

(After finishing the first intense open water training, )

(Iron Girls are exhausted.)

Everyone.

Let's have a meal and cheer up.

Are you all right?

No. I think I can gather my senses after lunch.

Ma'am.

- I'm starving. - I'm really hungry.

(Moving to a restaurant quickly before Seo Yeon collapses)

It's pouring suddenly.

(It starts raining when they come near the restaurant.)

Go!

It's raining suddenly.

- A typhoon is approaching. - A typhoon is coming.

He says a typhoon is coming.

(A typhoon is moving north in Jeju. Would it affect their training?)

We're lucky that the weather changed after our swimming.

You're right.

Let's go to the restaurant here.

- Is it this place? - Yes.

- It looks nice. - It's healing training.

- Healing! - It's nice here.

Food tastes good on a day like this.

Hello.

We need a lot of food here since we burned a lot of calories.

Now, we are...

about to eat up anything.

After training in the morning, everyone got tanned...

- and looks tired. - We're tanned.

It's because we did our best.

- Didn't we? - You did.

It's wonderful to see...

- everyone improving. - That's true.

It's amazing. You're so good.

Today, I used our your head as a buoy,

and I relied on you very much.

My son tends to cling to me like that.

He feels scared when his feet don't touch the ground.

(In fact, their chemistry of father and daughter...)

(started from the first swimming training.)

(Her thrilling touch started from this time.)

(Grabbing)

(He felt it during the morning training.)

(Since the start of this training camp)

(Like cat...)

(and dog)

(When he distributed cycling shoes)

(Ju Hyun, )

(here are your shoes, size 10.)

(Creating a rumor that she has large feet)

(More childish than Childish Park)

(Glaring)

(They quarrel every time they meet.)

(But when Ju Hyun is having a hard time, )

(he's the one who worries most.)

(Captain always stands by her.)

(They argue but they're the closest.)

- It's okay. - I pushed your head too much.

- It was all right. - All right?

Then please excuse me next time again.

He feels scared when his feet...

- don't touch the ground. - You were like father and daughter.

That's true.

Here's your food.

It looks so good.

Would we have enough food?

Sure.

This is what athletes usually say after training.

You've become a real athlete.

This is what they think when athletes eat.

The taste doesn't matter.

- I need to fill my stomach. - They want to have enough food.

Thank you.

- Thank you for the food. - Enjoy.

- Thank you for the food. - Thank you for the food.

- It's mackerel. - Enjoy it.

- It looks so nice. - It really looks good.

(Mackerel sushi to fill carbohydrates)

I'll eat these up.

We always do that.

(Dashing to food as usual)

Is it good?

(Dashing to food as usual)

(Let's eat these up in earnest.)

Do you like it?

(Devouring at one bite like beasts)

It's so good!

I love it.

- It's good, right? - It is.

You can take it.

(What's the next target of these beasts?)

Thank you.

Grilled mackerel and mackerel braised in soy sauce.

This is it.

(Attacking the broth first)

It's hot.

- It tastes insane. - And...

This broth tastes crazy.

Mackerel braised in soy sauce and grilled mackerel.

This is it. It's so good.

It's unique.

It has mackerel braised in soy sauce but it has no fishy smell.

(Eating intensely)

You can have it.

The broth tastes...

(Captain joins them in eating vigorously.)

You're eating it so well.

When you see someone eating food,

you can tell whether they attract luck or push away luck.

How do you know?

Some eat as if they'd push away luck, those who nibble on food.

Do you mean those who pick at their food?

(What do you think about me?)

All right.

(Do you think I'm attracting luck?)

It's almost like how a slave eats food.

- It's not attracting luck. - A laborer.

(She became a farmhand, unexpectedly.)

- It's not attracting luck. - A laborer.

Right.

(In fact, she's a lucky charm.)

It's clearing up again.

The weather changes so quickly.

You can't help getting tanned in this weather.

Right.

It pours, and then it's sunny.

The weather makes you tanned.

- as if grilled front and back. - Right.

I'm worried that...

only my teeth will stand out later.

Even now, I only notice your teeth.

When we were sleeping last night,

you smiled, and your teeth were the only thing I could see.

- Because she's so tanned? - Yes.

(Uie's teeth are shining.)

You look like a team of athletes.

- Right? - And you look so natural.

Athletes go through tough training...

and eat meals together.

- It's like a family. - You see them more often.

- So... - Right.

You're like a family.

There's one thing we haven't done in Jeju Island.

What is it?

We trained for cycling and swimming.

- We need to run. - Running.

Yes, we have to run.

- On our first day, we ran 5km. - Yes.

I kept the record since then.

(Do you remember their first running record?)

(A month and a half ago)

(They ran 5km for the first time.)

(The first long-distance running wasn't easy.)

(The first 5km record of Iron Girls who ran with an iron will)

(Uie's 5km record: 31 minutes 42 seconds)

(Ju Hyun's 5km record: 36 minutes 20 seconds)

(In Ah's 5km record: 37 minutes 6 seconds)

(Seo Yeon's 5km record: 38 minutes 17 seconds)

(Uie's average pace: 6 minutes and 20 seconds)

(Ju Hyun's average pace: 7 minutes and 16 seconds)

(In Ah's average pace: 7 minutes and 25 seconds)

(Seo Yeon's average pace: 7 minutes and 39 seconds)

(Except for Uie, everyone's record is over 35 minutes.)

Let's aim to run 5km in less than 30 minutes.

So today, like a test,

we'll see the record when you run at the individual pace.

The reason we're doing this training is...

After ten days, for the first time,

(After 10 days, for the first time!)

you're supposed to enter a marathon competition.

- We? - After ten days?

(They'll enter a marathon competition.)

After ten days.

To fit a triathlon we'll do, it's a 10km marathon.

The 10km marathon is the most popular.

I've entered several competitions myself.

Whether you enter a race or not...

changes your attitude of preparing it.

- Captain. - Yes.

Can I get a medal?

Yes, if only you complete the course.

- If only you complete it. - Really?

- Then it will be our first medal. - Perfect.

And it will be your first record in a 10km marathon.

- So... - I'm getting excited, though.

September 1?

It's so close.

Today, I'll imagine I'm in a real race...

and run at my pace.

Let's make a tight preparation.

I'm scared.

(They thought the rain stopped, but it's raining again.)

(The storm is even fiercer.)

(Typhoon Jongari is going north on Jeju Island.)

(A typhoon warning is issued on Jeju Island.)

(The worst weather)

Gosh, it's pouring again.

It's raining as we start training.

It stopped but raining again. The weather is so unpredictable.

What a timing.

How come it rains when we're starting to run?

(An amazing timing for training)

(Windy)

It's windy.

It was hard to cycle against the headwind yesterday.

- Right. - How can we run in this weather?

(Very worried)

- I can't open my eyes. - What shall we do?

I need goggles.

- I think I need goggles. - Same here.

(Goggles are a must now.)

If you have goggles, wear them.

I can't see!

I need wipers on my goggles.

Right.

The rain... Goodness, wait.

Do we have to do this now?

Well,

we enjoyed food as our healing training.

- Yes. - Yes.

Now, it's time for killing training.

But this will definitely kill us.

This will be the killing training as we promised earlier.

- Okay. - We're going to run 5km.

- Goodness. I see. - So...

(Nervous)

(Their running course today...)

(is one with beautiful scenery...)

(along the coast of Jeju Island.)

(Actually, it's not.)

(Goodness, the wind!)

(Fierce headwind)

(Pouring rain)

(And...)

(an endless uphill road)

(The real outdoor running, different from a track)

(Today's goal...)

(is to shorten their records.)

(Their 1st 5km running, 50 days ago)

(That day)

(Today)

(How much have Iron Girls improved?)

If the pace is 6 minutes per 1km,

it will take 30 minutes for 5km. Keep that in mind.

Rather than running in pace with your colleagues,

- run at your own pace today. - Okay.

(They'll run at individual pace today.)

I'm curious about who will finish the last.

That will be me, definitely.

- That's me for sure. - Okay.

I'm curious about who that will be.

- Don't trust what she says. - I know.

I'm not a good runner.

She's like a top student who says she didn't study...

- and gets the first place in class. - Exactly.

She always talks like that.

- A top student. - Do this stretching.

Okay.

Warm up.

(Seo Yeon stretches to prevent muscle pains.)

Warm up. Okay.

First, run at your pace.

All right. Go!

(The 5km running begins.)

(Today's running course)

(Sinchang-ri Port)

(Yongsu Harbor)

(Uie, Ju Hyun, and Se Yeon start to run in line.)

(In Ah falls behind from the beginning.)

The headwind feels strong.

We're having a headwind.

(They face a headwind from the beginning.)

It's hard to move forward because of the wind.

The wind feels so...

- The wind in Jeju is crazy. - It's headwind.

(When everyone is having a hard time due to the wind)

We have unfavorable conditions for setting a record today.

It's hot and humid.

(Glancing others once)

Okay, let's go.

(She begins to widen the gap.)

You should run at your own pace.

(I got it.)

(Uie takes the lead.)

(The distance increases immediately.)

Uie has incredible stamina.

She's the top.

(Far away)

(Studying others' faces)

You can go.

- Uie, don't worry about us. - Don't worry about us.

Don't worry about it and go with your pace.

(Uie 1st, Ju Hyun 2nd, Seo Yeon 3rd)

(In Ah is behind on her own.)

The view is great.

- The view is really great. - The view is great.

How nice.

(Jeju's coastal view is still in sight.)

How pretty.

It's okay. I just mustn't stop.

It's okay.

It's okay.

(She seems relaxed for now.)

Okay.

(Seo Yeon, Ju Hyun)

(Uie is way up there.)

Her pace can be under 6km per 1km.

(We all wonder what Uie's pace is at.)

(The 1km notice)

(Uie goes past the 1km mark quickly.)

(Uie's 1km pace: 6 minutes and 11 seconds)

(Ju Hyun and Seo Yeon who are behind...)

All right. We've reached 1km at 6 minutes and 40 seconds.

- We've reached 1km? - Yes.

We've reached 1km at 6 minutes and 41 seconds.

(Current pace: 6 minutes and 41 seconds)

And 6 times 5 is 30. And 4 times 5 is 20.

That makes it 33 minutes.

- Okay. - We're at a good pace.

- Okay. Let's go. - Keep up the pace.

We just have to make sure we don't go past 7 minutes.

Okay.

(Ju Hyun and Seo Yeon are doing well to keep the 6-minute pace.)

Hey, what's up?

(Breathing out)

(Breathing out)

(The eldest breathes steadily like a machine.)

(And behind her...)

(In Ah seems to be struggling a lot more with the wind.)

(In Ah's 1km pace: 7 minutes and 5 seconds)

(She is lagging behind.)

(Actually, In Ah who is struggling on her own...)

(From their first meeting, )

(In Ah expressed her pressure for running.)

(I hate running so much.)

(I hate it so much!)

(She struggled a lot with the first running session too.)

(She devoted herself to her training sessions afterward, but...)

(Pain)

(In Ah's training log: I'm dying. Cardio must hate me at this point.)

(She still couldn't get close with running.)

(The issue of running that In Ah must overcome)

(Captain Kim waits for In Ah who is struggling.)

Okay.

(You're the best, Captain.)

Around 7 minutes and 30 seconds? What's your pace?

- Seven minutes. - Seven minutes exactly?

Okay. Seven minutes.

What's 7 times 5? Is it 35?

And 7 times 5 is 35.

You're at a 35-minute pace.

You're at a 35-minute pace.

- You were calculating that... - Yes.

And it took you over 30 seconds for that?

I got confused a bit.

- Well... - Everyone is running so well.

Gosh.

It'll be a fight for second and third.

(The other girls cannot be seen anymore.)

(Can In Ah close the gap?)

(Meanwhile, Uie is taking the lead.)

(Stable)

I can finally take some time to look at the view.

I couldn't see any of it while cycling.

(Yesterday's cycling session)

(He spotted dolphins.)

(Dophins appeared right next to her at the sea, but...)

(Don't look though.)

(Uie could only face forward.)

(Today, she is more relaxed than anyone else.)

(She is enjoying her run while enjoying the scenery.)

Okay.

(From any angle, )

(Jeju's scenery wants to make you run.)

(It's the perfect season to run.)

(What kind of scenery are you running in?)

(In front of Uie who was running by Jeju's coast, )

It's an uphill road.

(an uphill road appears.)

(Even when she enters the uphill road, )

(she keeps her pace.)

Gosh, the wind!

(Even when the strong wind blows against her, )

(Ace Uie does not get affected.)

It's 2.5km. Let's go.

(She passes the 2.5km mark in just 15 minutes.)

(Laughing)

(Uie enjoys her run once again with her iron stamina.)

(With her stable form and breathing, )

(she runs and runs.)

(Watch notification)

I have 2km left.

(She passes 3km in 18 minutes and 12 seconds.)

Thirty minutes?

Let's go for it.

(Uie's goal: Completing the run in 30 minutes)

(Previous record: 31 minutes and 42 seconds)

It's because of the length of her legs.

It doesn't make sense.

(Uie has disappeared from Ju Hyun and Seo Yeon's sight.)

My pace is 6 minutes and 30 seconds?

That's fast.

(Ju Hyun's pace: 6 minutes and 30 seconds)

Great.

(Her pace is reduced by 46 seconds than her previous run.)

(Seo Yeon...)

When I went jogging in the morning,

I was at an 8-minute pace.

(Commentating mode all of a sudden)

Or a 7-minute pace.

It was a light jog.

But now I'm at a 6-minute...

and 45-second pace.

The conditions are different than usual,

but...

I will overcome the forces of evil.

(This must be a hero movie.)

I will do my best.

I'm trying hard for this.

(While Commentator Jin was doing her commentating, )

(Ju Hyun went ahead by quite a distance.)

(Without looking exhausted, )

(she enters the uphill road.)

I've reached 2.4km!

(Childish Park's energy goes up after reaching half of the course.)

Great.

Great. I've become stronger.

I've already reached halfway.

(She has equipped the positive Iron Girl way of thinking.)

How pretty!

Let's go!

My posture looks a lot better now, right?

(Something seems different about her.)

(During the previous 5km run, )

(her core gave in and her upper body shook too much.)

(She was barely able to keep herself standing.)

(Now, her upper body doesn't move as much...)

(and her posture looks a lot more stable than a month and a half ago.)

I've improved so much. I can talk while running now.

(She feels her improvement.)

Gosh! I've reached 3km!

I've reached 3km!

(Ju Hyun reaches 3km in 2nd place.)

(Ju Hyun's pace: 6 minutes and 39 seconds)

(Meanwhile)

My pace is at its worst.

We've reached 2km. Your pace is at 7 minutes and 34 seconds.

(In Ah's pace: 7 minutes and 34 seconds)

I'm so exhausted.

I'm so exhausted! I'm too tired.

(She's almost crying out while running.)

What is your heart rate now?

- I'm at 164 bpm. - You're at 164 bpm?

- Yes. - Gosh, you're doing your best.

I told you I was bad at running!

- With that kind of heart rate... - What about you?

I'm at around 110 bpm.

- You're at around 110 bpm? - Yes.

(Captain Kim's heart rate is at 116 bpm.)

If you're at 164 bpm, you're at 80 percent.

I'm at 80 percent?

If you keep yourself at 160 to 170 bpm,

your stamina will increase as you will grow from this.

It feels a lot different from swimming.

(Sports Genius In Ah's weak point: running)

I told you I was really bad at running.

Gosh, how can I run 10km?

(She seems to lose more confidence with running.)

(While In Ah is falling behind...)

Okay!

The last 1km.

(Uie has already gone past the 4km mark.)

(Without looking exhausted, )

(she climbs up the uphill road.)

(Great!)

It's the last 1km.

(Uie keeps her big smile.)

(To Uie who is smoothly heading to the end, )

(rain starts falling.)

It's raining so much.

Gosh, this is quite bad.

(Because of the wind against her, the rain is directly hitting her.)

I have 500m left.

(There are 500m left after 27 minutes.)

I don't think I can make it in 30 minutes.

(In the rainstorm that is getting stronger, )

(she aims for her goal of coming in 30 minutes...)

(and increases her speed.)

I have 200m left, but where is the end?

(The final sprint)

(This is the final destination.)

(Uie)

(She runs on the uphill road as she still has enough energy.)

Where does it end?

(She runs on the uphill road as she still has enough energy.)

It ends here?

(Has Uie completed the course in 30 minutes?)

(Uie checks her record right away.)

I made it in 29 minutes.

(Uie's 5km record: 29 minutes and 8 seconds)

(Average pace: 5 minutes and 49 seconds)

(She manages to complete the course in 30 minutes.)

(Previous record: 31 minutes and 42 seconds)

(Today's record: 29 minutes and 8 seconds)

(She shortened her record by 2 minutes and 34 seconds.)

(She doesn't even look tired.)

(Morning swim of 1.8km, run of 5km)

(She doesn't even look tired.)

(While Ace Uie has stably completed her 29-minute run...)

Where's Kim Yu Jin?

My gosh.

(Childish Park gets mad because of the wall of the ace.)

It's making me feel mad.

(Childish Park gets mad because of the wall of the ace.)

Gosh.

It keeps going up from here.

(It keeps going up from here.)

(Struggling)

It feels different.

My pace is slowing down right away.

(Looking)

Give me a ride! Please!

(She asks for the drone's help.)

My pace has slowed down so much.

(She asks for the drone's help.)

The last 1km!

(The rainstorm is strong at the 4km mark.)

Gosh, what's going on?

(Gosh, what's going on?)

(Ju Hyun's pace: 6 minutes and 58 seconds)

I have 500m left.

Running 500m is nothing.

(Her dogged spirit comes out.)

There it is. It's an uphill road at the end.

(The last uphill road for the finish)

Park Ju Hyun!

Ju Hyun!

Park Ju Hyun!

(Focused 100 percent until the end)

You have to come here.

(Will Ju Hyun be able to shorten her record?)

Here!

(Ju Hyun's 5km record: 32 minutes and 40 seconds)

(Average pace: 6 minutes and 32 seconds)

Gosh, I love you so much.

Great job. You didn't stop in between, right?

- You didn't stop, right? - This liar.

I happened to reach 5km while running.

- You were at a 5-minute pace? - Yes.

I was at 6 minutes and 30 seconds.

I was at 5 minutes and 50 seconds.

(Shaking her head)

She's unbelievable.

(No one can catch up with the unrivaled Uie.)

Gosh, the length of your legs.

I'm really sorry.

I can't do anything about my legs.

Our legs look short because of you.

I can't do anything about that. I'm sorry.

(While there is an argument about the length of her legs...)

Gosh!

(Seo Yeon who was in third place...)

I have 1km left!

(has 1km left.)

I have 1km left.

(Screaming)

(She is keeping herself together with her screams again.)

(Even with the rain pouring on her, )

(the one with Iron Mentality cannot be stopped.)

(Final destination)

(She enters the uphill road while controlling her breathing.)

It's Seo Yeon! Seo Yeon!

- Seo Yeon! - Seo Yeon!

(She responds with a pose of a movie hero.)

Jin Seo Yeon!

(She responds with a pose of a movie hero.)

(The last spurt)

(Tireless Seo Yeon's sprint)

(The training sessions that she never missed finally pay off.)

- Gosh, look at her sprint! - Go until the end!

- Stop the watch right away! - Stop the watch right away!

Stop the watch right away!

You sprinted at the end?

(Today's record: 35 minutes and 19 seconds)

On the uphill road?

(Seo Yeon also shortened her record by 2 minutes and 58 seconds.)

(Jin Seo Yeon: 35 minutes and 19 seconds)

(The ones who completed the course...)

(have shortened their records.)

(In Ah is the only one left.)

You're slowing down.

Your pace is at 7 minutes and 40 seconds.

At this pace,

it will be over 37 minutes.

(Her previous 5km record: 37 minutes and 6 seconds)

I'll go over 37 minutes at this rate.

We're in the second half now.

(She must run to shorten her record.)

You're at a good speed.

(She brings up the speed a bit more.)

Your pace is at 7 minutes and 5 seconds.

(Current pace: 7 minutes and 5 seconds)

Your pace is at 6 minutes and 40 seconds. Nice.

(Current pace: 6 minutes and 40 seconds)

(She uses all her might to bring up the pace.)

I'm feeling really sick.

I feel like throwing up.

(She starts feeling more pressuring on her chest.)

(Checking her pace)

(In Ah is sweating buckets.)

(On top of that, )

(she feels pain in her sides.)

(This is called the side stitch.)

(It haunted In Ah even during the previous run.)

(A pain that occurs to runners due to an increase of breathing...)

(and abdominal distention)

(A good stretch before the run will help.)

(Walking when this occurs will help ease the pain.)

We have gone past 26 minutes.

Your pace is at 7 minutes and 10 seconds.

(In Ah ends up walking again.)

My sides hurt so much.

(In Ah ends up walking again.)

- My sides won't get better. - Your sides?

(A sharp pain at the sides)

- Are you exhausted? - My sides.

What is your heart rate right now?

- It's at 170 bpm. - It's at 170 bpm?

My sides hurt so much.

- I'll just rest for ten seconds. - Okay.

(Has she reached her physical limit?)

(After walking while controlling her breath...)

- It's at 168 bpm. - Show me.

- It's going down. - You're recovering.

It's at 165 bpm. Great.

(Fortunately, her heart rate comes down.)

You're doing great.

- Let's run! That was ten seconds. - Okay.

Okay.

The pace has slowed down.

Just as we speak,

we are going past 4km.

- We are going past 4.1km. - We have 900m left.

We have gone past 30 minutes.

(Around 30 minutes have passed with 900m left.)

(Although it may be tough and painful, )

(I will run until the end.)

(Let's do this, Iron In Ah!)

It's an uphill road.

(They enter the uphill road.)

It's an uphill road.

There's always a downhill road after an uphill road.

(There's always a downhill road after an uphill road.)

Keep going.

I think I'll set the same record.

- Let's go for less than 37 minutes. - Okay.

I think we'll reach a little bit past 37 minutes at this pace.

Hang in there.

(Captain Kim keeps her goal and mindset together.)

The pace is at 6 minutes and 5 seconds.

This is a good pace.

I told you it was possible.

You are someone who is capable of doing this!

(You are someone who is capable of doing this!)

I hear them.

(In Ah runs while hanging on to her mental strength.)

I see the end.

(The final destination finally appears.)

I see the end.

You're almost there, In Ah!

Seol In Ah! Captain Kim!

- Okay. - Seol In Ah! Captain Kim!

- Just a bit more. - Let's go!

Until the end.

- You're almost there. - Until the end.

Keep going. Just 2m more.

(Swaying)

I'm done.

(She dives into the cameras as her legs give in.)

Gosh.

- You got 36 minutes and 15 seconds. - Splash some water on your face.

(In Ah's 5km record: 36 minutes and 15 seconds)

(Average pace: 7 minutes and 15 minutes)

Great job.

It feels like the end of a triathlon.

(She definitely has given it her all.)

A triathlon.

(She definitely has given it her all.)

(Previous record: 37 minutes and 6 seconds)

(Today's record: 36 minutes and 15 seconds)

(In Ah has tried her best and shortened 51 seconds.)

(The last training session ends with the signs of growth.)

This is amazing.

- The wind is amazing. - Gosh.

- Take a seat, In Ah. - I'll stand for a while.

- Stay standing for a while. - I can't get myself together.

- In Ah did her best. - Right.

I checked how she looked after the run.

She had the same face of a full workout.

In Ah got 36 minutes and 15 seconds.

- She shortened it by a minute. - Well done.

She did really well.

It's really hard to shorten it by a minute.

Right.

Why are all of you so good at running? I can't catch up.

I thought that In Ah had good stamina...

as she was a good swimmer.

- But she should practice running. - Right.

Her running wasn't as good as I thought.

- Did you get your record, Uie? - It was the wind.

I finished at 29 minutes and 8 seconds.

- That's a top ranker's record. - That's amazing.

- Gosh. - She's definitely a former athlete.

You might place first at this rate.

So Uie shortened her record by around two minutes.

Right. Two minutes.

I came in at 36 minutes.

Right. That's around four minutes shortened.

- I got 35 minutes and 19 seconds. - You got 35 minutes and 19 seconds.

- That's 3 minutes. - She shortened it by 3 minutes.

- Everyone shortened their record. - That's amazing.

During the first 5km run,

I wanted to die after every 1km mark.

- Me too. - Right.

But I was able to control my pace...

without forcing myself.

- Your body never lies. - Right.

That's another saying from your book, right?

No. It was a saying that impressed me recently.

- Well done. - Well done!

You all did amazing.

The Jeju session was intense.

Gather up, everyone.

- We have to end with this. - Gather up.

- We have to do this. - We will do it every single time.

- All right. - To finish the race.

- To finish the race. - Right.

- Iron Girls! - Iron Girls!

(They participate in their first real competition!)

(A 10km marathon)

(Very...)

(nervous)

(They start the marathon feeling nervous.)

(I'm really stuck.)

(People overtake them.)

(Their visions are blocked.)

I feel like dying.

(The side of Uie we see for the first time)

(In Ah's chronic issue, the pain in her side)

(I'm about to die.)

(Why did I agree to do this?)

(Can Iron Girls complete the race?)

(My goodness!)

(The next special training...)

(is at a 5m-deep diving pool.)

(This is scarier than the sea.)

(Into this scary pool, )

(she dives in without hesitation.)

I'll try.

(Our ace, Uie)

(From a difficult technique...)

(to a physical fight with Coach Heo?)

(There's nothing more to teach her!)

(And one person with a serious expression)

(At the deepest water level, )

(Seo Yeon's fear of water worsens.)

- I'm tearing up. - Are you?

(Can Seo Yeon overcome the fear?)
