(2024 tvN original)

(2024 tvN's Insane Project)

(Introducing 4 players taking part in this insane project)

(Very strict with her self-care)

I meditate for 1 hour at 4am.

Then I do yoga for an hour.

(Meditation at 4am, yoga at 5am)

In the afternoon, I go to a gym for weight training.

After four hours of weight training,

I do Muay Thai in the evening.

(A workout fanatic who does 3 types of exercises a day)

("I can do it!" She dashes head-on with an iron-like mindset.)

(An iron woman with an unshakable mentality)

(Iron mentality, workout fanatic, Jin Seo Yeon)

(She loves water.)

I started swimming in middle school.

(She used to be a professional swimmer.)

I think I have good endurance.

Hanging in there, holding it in, and running a long distance.

Recently, I've been trying to get a certificate for free diving.

I went to a swimming pool most frequently.

I try to work out every day.

It has become a habit,

so I need to work out to feel like my day has started.

It's just like drinking iced americano in the morning.

I'm the ace of triathlon.

How is she so good? She's amazing.

She is really good.

(Stamina Queen, the ace, Uie)

- I can feel the power. - You're so good.

You're good.

(She blushes at the compliments,)

(but she surprises everyone as soon as she starts working out.)

When In Ah works out,

her facial expression changes completely.

Taekwondo, pilates, futsal,

surfing for a bit, skateboard, and jiu-jitsu.

I guess active activities...

suit me well.

She's a sports genius.

She really is a sports genius.

She is born with a great athletic ability.

Triathlon is her specialty.

(Introverted In Ah, Sports Genius, Seol In Ah)

(And...)

(a newbie actor that left a strong impression...)

(with her role in "Extracurricular")

- It's so cool. - Goodness.

Ride this and shoot

(Very cheerful)

It's exciting.

(She is a mood maker.)

It's fun.

You're so awesome!

One minute has passed.

(She has the worst stamina.)

That's a lie.

Ju Hyun has very strong willpower.

(Tenacious, Childish Park, Park Ju Hyun)

We are four women with guts.

- We need to go the distance. - I'm satisfied with that.

(The women give it a go at triathlon for the first time in Korean shows)

(But they only have 4 months left.)

We don't have enough time.

I was this weak.

"If I can't do this,"

"isn't it pretty hopeless?" That was what I thought.

Nobody will run for me. I must do it.

(They challenge their limits.)

It was so tough that I wanted to give up.

You're bleeding. Are you okay?

I can't do this.

(Blood, sweat, and tears)

I'm tearing up.

It's making me swear.

(It even makes them swear.)

Amazing. They're insane.

You can do it.

My calves are about to explode.

Does Ju Hyun have this on?

(When one flops down, her teammate comes to hold her hand.)

Here... Don't cry.

It must've been tough for you too.

I was very grateful.

I thought I had to work even harder.

("I must work even harder!")

I will tell you, it's okay. Gosh!

Stop.

My goodness. Let me see.

Is Uie on her way?

(Even when one falls, she has teammates waiting for her.)

Ju Hyun, you can do it!

Ju Hyun is amazing too.

(Women as strong as iron)

Uie, come here.

- You did so well. - Are you crying?

Good job.

(Their struggles to take part in a triathlon match...)

- Iron! - Girls!

(start now.)

(Last summer)

I'm sure everyone feels the same.

(Sighing)

Finally.

(Standing up)

By the way,

please film my dressed-up self in detail.

You won't see this ever again...

on this show.

(She is showing off her bright side.)

(Charming)

Play it in slow mode.

(Jin Seo Yeon, actress)

I'm going to plan a workout schedule.

Morning workout, afternoon workout, and evening workout.

That's my plan.

From what I checked, professional athletes...

work out in the morning, afternoon, and so on.

That's what we should do too.

My gosh.

- My gosh. Hello. - Hello.

I thought I was the earliest. Hello.

(Hugging without saying anything)

Our athlete.

- Our athlete. - I'm not.

(Uie, actress)

Exactly, so...

(Jumping to it straight)

So what should we do?

It's my first time meeting you, but it doesn't feel that way.

- Me too. - Why is that?

Because the blood of an athlete...

- I... - is boiling inside us.

What is it? I'm really seeing you for the first time.

- I don't know. - With this...

(At that time, someone is pacing in front of the door.)

- Hello. - Hello.

(Polite)

You're so pretty.

(Seol In Ah, actress)

You're so pretty.

You didn't say that to me.

(Goodness)

- For you... - Hold on.

- No, for you, as an athlete, - What? I'm also...

I could feel your vigor. You're so pretty.

Hello.

- Hello. - Hello.

- Hello. - Hello.

- Hello. - Gosh, you're so pretty.

- Show your face to the camera. - My gosh.

You didn't say that to me.

I'm going home.

(Park Ju Hyun, actress)

- Hello. - So...

So...

Exactly. How far were you with your conversation?

Have you met before?

- This is my first time meeting her. - Hold on.

- Did you meet for the first time? - Yes.

You looked as if you knew each other.

- I tend to be quite nosy. - You're so cool.

By the way, I don't know your age.

- I was born in 1994. - Year 1994.

- I was born in 1996. - You're younger?

I was surprised too, honestly.

- Which year were you born? - In 1988.

I was born in 1983.

Let's talk about that.

How did you decide to do this?

I'm curious too.

How did you feel when you first heard about it?

Did you immediately decide to do it?

- No. - Not at all.

You all must've given it...

- a lot of thought. - That's right.

Right?

- It was hard to make up my mind. - Exactly.

We all have experiences with preparing for a movie or a drama.

At first, you think,

- "How can I do this?" - That's right.

But in the end, you pull it off really coolly.

- Yes. - We all have experienced it.

So I thought to just consider it as joining another movie.

I'll consider this as another movie.

- It'll be a very tough movie. - Exactly.

Yes.

I won't think of this as a variety show.

This is a movie where four women give it a go at triathlon.

A movie.

I'm thinking of this as a documentary.

You could give up on a documentary.

- Right. - Your characters are fixed.

You have to make it to the end no matter what.

We must make it to the end.

(Director Jin wants a closed ending.)

It's too harsh.

- This is news to me. - Listen.

- If it's a documentary... - I can't do this.

- If it's a documentary... - I'm tearing up.

- You're the protagonist. - I'm sorry, but...

- Are you going to do it or not? - Wait.

- I'm really scared. - Are you going to do it or not?

Make up your mind now.

(Seo Yeon...)

- You must do it. - She's scary.

Other characters will get injured, fall down,

and be wrapped in bandages.

Our role is to make it to the end.

You have very strong willpower.

- She has an amazing mentality. - Seriously.

If you don't think about it that way,

- you can't do it. - This movie will become a hit.

I agree.

Four of us including me all are...

Can I say this?

We all have guts. Can I say this?

- Really. - We don't say, "I can't do this."

"I won't do this."

We seem to be the type of people who keep doing it until we succeed.

- That's right. - Right.

I have to succeed if I have to do it.

Exactly.

Uie, you have scary eyes.

You said you wanted to go home.

- Why did you suddenly change? - You really looked scary.

Right? I'm not the only one who felt that, right?

(Eyes opened wide)

I have to succeed if I have to do it.

How are her eyes so round?

(The older members are scarily passionate.)

- I was so surprised. - Really...

How did you guys decide to join?

(Hesitating)

Actually,

I can't sleep well.

I've been taking sleeping pills for five years.

But it made me angry.

"Why must I take these pills..."

"to go to bed?"

My thought process went, "Am I not tired enough?"

So I made myself even busier...

and overworked.

I think that's why people think I live a productive life.

Actually, I did that to sleep.

I worked more to sleep well.

It is a healthy image,

but I was never healthy, which is ironic.

I wanted to use this chance to really become healthy.

(She wants to get back her real health from this.)

If I take sleeping pills, I cannot focus on filming.

I stopped taking pills since last year.

I stayed awake for 3 to 4 nights,

and my immune system crashed. So I went to a university hospital.

I had to take 24 pills just for my skin.

And...

it first came to my mind...

that I wanted to become healthy.

Firstly, my stamina...

has been worsening from living an irregular life.

I had to use my mental strength...

to just maintain my physical health.

That worsened my ability to focus.

Improving my stamina is my first reason.

And I have a lot of issues.

I was peculiar since young,

so I wore a cast on my wrists and my ankles six times.

I'm allergic to the sun too.

- I completely... Yes. - Does your skin break everywhere?

I become a mutant.

I was told that I had a lot more issues.

You will play that kind of role.

(Pardon?)

A mutant?

- Despite having... - A lot of issues?

a lot of issues,

you will overcome it and win. That's your character.

(She is at a loss for words from her passion.)

You are allergic to the sun.

You have a lot of weaknesses that hold you back.

- Despite those issues... - Is a happy ending the only way?

In the end, you'll go the distance.

(The only acceptable ending is making it to the end.)

- Completing the race? - Yes.

But seriously...

You're the oldest member here.

Don't you suddenly feel more courageous?

- Don't you? - Yes, she leads us well.

I agreed to join the show because I thought I couldn't do it.

(Pardon?)

I can't swim.

I can't swim.

- Really? - I can't.

(You want to enter a triathlon, but you can't even swim?)

I can't swim.

I can't swim.

- Oh, is it? - Yes.

(You want to enter a triathlon, but you can't even swim?)

Seo Yeon, I...

can't ride a bicycle.

- For real? - Yes.

I can't ride a bicycle.

- For real? - Yes.

(Wait. Is this even possible?)

I'm really scared of it.

Surprisingly, you can't ride a bicycle.

When you say you can't, how bad are you?

- I can't do it at all. - I can't even lift up my legs.

I'm scared to put my feet on the pedals.

I panic when the water level is higher than my waist.

You can't swim at all?

You're afraid of water, right?

- In a public bath, - Yes.

I almost drowned to death when I was young.

- Oh, when you were young. - Do you remember?

I saw a panorama.

So when I told people that I can't swim,

and that I'm entering a triathlon as a person who can't swim...

by practicing for three months...

Many people told me that it was impossible.

I see.

(Worried)

You must've hesitated to join since you can't ride a bicycle.

Right. You volunteered even though you can't ride a bicycle.

When there was a bicycle scene,

I always used a stunt double.

It's funny to use a stunt double for riding a bicycle.

A stunt double came to the set,

and asked, "What should I do?"

Then she'll be asked to ride a bicycle.

This happened a lot to me.

(A stunt double's job for Uie: Riding a bicycle)

(Uie's bicycle scene in a drama)

(Stunt double's feet)

(Uie can only shoot her upper body,)

(or when she's sitting at the back.)

(She's really scared.)

(To Uie, this is a horrendous action scene.)

(She's scared in real.)

People say I can learn to ride it.

But I tried for 20 years, and I still can't.

It's not so easy for me.

When people think I can't do it...

But when I make it happen, I feel good.

Even to myself,

there are some things that I believe I can't do.

When I throw myself out of my comfort zone,

I trust that I will make it happen.

If I get to ride a bicycle through this, it'll be great.

I think it will be fun.

(She's challenging herself to overcome her bicycle trauma.)

(Screaming)

(We didn't say it would be easy.)

(I don't think I can do this.)

(She's about to cry.)

(Horrified)

(Even if fear overwhelms)

(Gasping)

(I'm having hyperventilation.)

(There's no giving up.)

(Her eyes are fiery.)

(Will they be able to overcome their traumas...)

One, two, three.

(and finish the triathlon?)

Don't you think we'll all cry after finishing the triathlon?

This is the ending of our movie.

Can we cry?

- Look. - Or can't we cry?

- We'll bawl our eyes out. - Look.

We'll bawl our eyes out. You know the typical group hug?

(She's amazing.)

You don't know. I easily get tired.

You need to practice for that.

- Triathlon is a test of endurance. - Yes. You're right.

- We need to practice from now on... - Yes.

and gradually improve every step,

and every second.

That's right.

We need to work out every day.

We only have a short period of time.

So we need to do this every week.

It's a test of endurance.

- Uie isn't focusing. - Working out every day...

I'm focusing. We should exercise every day.

- Every day. - Of course.

- Every day? - Yes, we need to do it every day.

We should practice every day.

Were you thinking of working out every once in three days?

- Two days? - Every other day?

Isn't working out every day bad for your muscles?

We're not doing weight training all week long, are we?

For example, it was leg day today.

- The next day will be upper body. - Yes.

The following day will be an abs day.

You're training different parts every day.

Exercising every day doesn't use the same muscles...

and damage them.

Do you go to the gym every day?

Yes.

I sleep with my gym clothes on.

Oh, right. I know about this fact.

If I think that I won't want to work out tomorrow,

I'll wear my gym clothes to sleep.

I saw this...

in a book.

- "Sleep with your gym clothes on." - I saw it too.

If I end up just going out with my sneakers on, it counts.

We said this earlier,

but I feel like we've known each other for a long time.

I thought you two were friends.

I saw her for the first time.

It's my first time to see everyone.

It's amazing.

I don't feel like it's my first time seeing you all.

Right. I feel comfortable.

I hope we can make group T-shirts.

So I...

- Did you find something? - wanted to make a character.

- Did you find something? - I'm not good at drawing,

- but something like this. - What is this?

(Bursting into laughter)

Do you see what I mean?

You're seriously bad at drawing.

- It's shocking. - Hey!

(Don't hurt my feelings with facts.)

- Something like this? - Yes.

Having our own character...

can help us make group T-shirts.

(Her wish was embodied...)

(in the creation of the Iron Girls' characters.)

(Jin Seo Yeon)

(Uie)

(Seol In Ah)

(Park Ju Hyun)

(These characters will grow together with Iron Girls.)

When is the triathlon?

- We're aiming for October. - Yes.

It's the World Triathlon Cup Tongyeong.

We are going to have our first training camp.

- You have many questions, right? - Yes.

First, we'll go and see the triathlon.

- To see? - I see.

- We're just watching them? - We need to see it.

We'll get a sense of reality, then.

You're scary.

It'll be fun to watch.

(How will our first training camp be like?)

(One week later)

(Changwon)

(The day of the triathlon)

(The three gateways to becoming an Ironman)

(Swimming for 1.5km)

(Cycling for 40km)

(Running for 10km)

(Ironmen gathered in one place from all over Korea.)

(However)

(It rained heavily in the country throughout this week.)

(The rainy season started on the day of the competition.)

(3.15 Ocean Nuri Park at 5:20am)

(The government issues heavy rain and wind warnings.)

(Eventually)

Due to the heavy rain, cycling is canceled.

Is that possible?

It's going to be an aquathlon. Swimming and running only.

- They'll do it today. - I see.

Aquathlon isn't canceled in this weather.

For real. I thought the whole thing would be canceled.

In the rain, the water level will be higher.

Isn't it dangerous?

(Worried)

They're doing this?

(Ironman does it.)

(The heavy rain can't block Ironmen's passion.)

(They're enjoying the heavy rain.)

Many people are going for this.

(Many Ironmen came all the way here to enjoy this hardship.)

Let's do this safely!

- You can do it! - You can do it!

They're all so cool.

(Look!)

My goodness!

- My goodness. - Oh, my.

It's amazing.

- Kim Dong Hyun. - Hello.

My goodness.

- Kim Dong Hyun. - Hello.

- Hello. - Oh, my.

- Seriously. - Your lips are chapped.

- What happened to your lips? - It's not that.

(The strenuous training even made Dong Hyun's lips chapped.)

I trained too hard.

How long did you prepare for this?

Less than two months.

- Two months? - Only two months?

But he was already good at running.

Yes, we have different physical strength.

- He's a good runner. - I'm not normal.

- Right. - He's not normal.

But you look great.

- For real. - You're really "Physical: 100."

(Posing)

- I hope they don't cancel it today. - Be safe.

It's good to see a person that we know.

- One, two, three. Let's do this! - Let's do this!

- You're the best. - You can do it!

- Yes. - You can do it.

- You can do it! - Can we go here?

Now, we'll move to the swimming pool...

by swim cap color.

Green cap color, first.

Please start within your group.

- Make sure to be within your group. - Oh, my goodness!

They must be nervous.

(Top group athletes enter first.)

The area became qUiet.

(The atmosphere suddenly changed.)

The atmosphere here suddenly changed.

You can do it! It stopped.

- Eight, seven, six, - It's going to start.

five, four, three,

two, one, start!

(The competition officially begins!)

It's amazing!

- My goodness! - Oh, my. It's amazing!

- They're so cool! - Oh, my.

- They're going to swim this way. - Oh, like this?

Can you see the number three?

Oh, they're making a round?

- Then, they'll go from 1 and 2. - That's amazing.

(Today's swimming course: They're going to make two rounds.)

It'll be physically difficult.

(The swimming course is 1.5km.)

They're making two rounds.

- It's crazy. - This is amazing.

(She's having a headache.)

How can we swim two rounds?

I'm amazed that they're all floating.

Will I be able to do that?

(A spectacular sight created by 600 triathletes)

They enter the water without hesitation.

(They dive into the water without hesitations.)

Kim Dong Hyun is entering soon!

- Kim Dong Hyun, you can do it! - Kim Dong Hyun!

Kim Dong Hyun, you can do it!

- You can do it! - You can do it!

(He suddenly stops.)

(Hesitating)

(He enters the water safely.)

- Let's go. You can do it! - I can see him.

He's swimming.

(Holding and releasing breath)

(Holding and releasing breath)

It's his first time to try.

I thought his swimming skills might be lacking.

But he swam like an athlete.

He's there. The first one.

- It's amazing! He's so fast! - Where? There?

- Here. - Something is blocking him.

- There. Can you see his arms? - Oh, yes.

Look at the difference. He's unbeatable.

(The leading athlete pulls ahead with a huge gap from the start.)

(An overwhelming speed)

It's amazing.

(Pulling ahead with a massive lead all the way to the finish line)

That athlete is...

He's so cool. Everyone is.

I think it only took ten or so minutes.

He's going in the water again.

- He's going in again! - Really?

The one wearing black.

He's there but overtaking the others.

Where is he?

He's next to the one wearing orange.

He's wearing a black swimming cap.

He's so fast!

It's tiring even to watch them swim.

This is impossible.

They're all energetic.

Right? They don't get tired.

Their energy is amazing.

(This is the energy of triathletes.)

The first athlete is coming in.

- They're out. - My goodness.

(The current 1st-place: 20 minutes and 23 seconds.)

They're so fast.

(They head to the next course immediately.)

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

He's like an athlete.

You can do it!

Oh, he takes off his swimming suit while running.

- When you run after taking it off, - No, but...

I think my heart will be beating so fast.

- Yes. Mine too. - My goodness.

My heart is suddenly beating so fast.

How would it feel like to be the first person to finish?

Originally, cycling would be the next course.

They change to cycling here.

But cycling is canceled today.

He's changing his clothes.

(The 1st athlete starts running.)

(Other athletes finish the long swimming course,)

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

(and joins the running course.)

- They're all so cool. - Really.

(Powerful)

- Did you see that? - You can do it!

- He used his mouth. - You can do it!

- You can do it! - You can do it!

You can do it!

(Laid-back)

You're cool!

- He's laid-back! - He's cool!

He's laid-back!

- You're amazing! - You're cool!

(The first female athlete to be seen)

- You're amazing! - You're cool!

- She's so cool. - She's so amazing.

She must be exhausted but she's running!

She's amazing.

(The female athlete is amazing.)

Won't running be more difficult?

I think everything will be tiring. This is impossible.

Everyone is challenging themselves in life.

- Right. That's true. - There are 600 athletes here today.

Yes, that's right.

- Aren't they challenging their own? - Yes.

They aren't trying to overtake others.

- Right. - They fighting their own records.

Something is filling...

- my heart. - Yes.

They're all amazing.

(Most of the athletes entered the running course.)

Where is Kim Dong Hyun?

(At that time, at the swimming section,)

(someone is swimming with his swimming cap on his hands.)

(Kim Dong Hyun finishes swimming: 37 minutes and 24 seconds)

Kim Dong Hyun, sir!

- Kim Dong Hyun! - You can do it!

- You survived! - Kim Dong Hyun, you can do it!

My goodness!

You can do it!

- My goodness. - You can do it!

- He came in. - He finished swimming!

- You can do it! - You can do it!

Wait. Are they running here?

- Yes, they need to go up. - They were running to go up.

Do they need to come down after going up?

(After 1.5km of swimming,)

(the next course is 10km of running.)

(They have to cross the bridge,)

(and circle the island three times...)

(in order to run 10km.)

They'll be exhausted to death, right?

This isn't easy.

- You're right. - You can do it!

(From now on,)

(it's a battle of mental strength.)

- They'll be tired. - They should be.

(From now on, it's a battle of mental strength.)

(Even Dong Hyun is tired.)

I've slightly lost my ambition regarding the record.

(In this moment, what matters more than the record is...)

(taking a step beyond your own limits.)

Even though they're exhausted, their feet are running.

Yes.

(They wait nervously for a long time at the finish line.)

How would they feel?

(At that moment,)

(one athlete is on his way back!)

(The lead runner heading towards the finals appears.)

There's only 300m left until he finishes.

- There's only 300m left. - Seriously?

Yes.

I want to take a photo.

I don't know why, but I want to.

- How will the winner look? - Okay.

(How will the winner look?)

(The lead athlete is running at high speed.)

He's entering!

My goodness!

(The 1st-place athlete finishes: 1 hour, 6 minutes, and 10 seconds.)

He's the one who gave us a sign.

He was the one!

- No wonder he was laid-back. - I knew it!

- Congratulations. - He's so cool.

- He's amazing. - The second-place winner is here!

(The swimming leader arrived in 2nd place.)

- You're cool! - He's amazing.

- Thanks for your efforts. - Chungnam PE High School rocks!

(Finishers are arriving one after another.)

Thanks for your efforts.

The female athlete has 200m left.

Athlete number 32.

She's coming. My goodness!

- My goodness! - She's so cool.

Oh, my goodness!

(Nationwide Triathlon Cup)

- You're amazing! - You're amazing!

- Thanks for your efforts. - You're amazing!

Thanks for your efforts.

They're all amazing. This is impossible.

(Nationwide Triathlon Competition)

(The sense of achievement is felt beyond the finish line.)

- Thanks for your efforts. - Thanks for your efforts.

(Athletes became exhausted after giving everything they got.)

My goodness. They must be so exhausted.

It seems like they’ve lost all their energy.

If they're exhausted without the cycling,

what will happen to us?

We're in trouble.

(Having mixed emotions)

They didn't do the cycling part.

Right, but they'll be exhausted already.

- Seriously? - They all can't speak.

That makes sense.

I'm already tired by looking at them!

You can do it!

(There's another person who endured this hard time.)

- You can do it! - You can do it!

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

(Kim Dong Hyun finishes the race!)

Kim Dong Hyun!

(Kim Dong Hyun finishes the race!)

You're amazing.

- My goodness! - Sir!

(Kim Dong Hyun made it.)

You finished!

(He's smiling for real.)

- I want that medal too. - Seriously.

You will!

Seo Yeon, shall we be cool,

and finish without crying?

No crying when passing the finish line.

- No crying? - Yes.

Let's smile.

Even though we're exhausted,

we need to smile when we're done.

- You can never cry. - I must smile.

There's no crying in the script.

(They finished watching the heartwarming game.)

(What's the next schedule for Iron Girls?)

- Yes. - Our first training?

When we get to the first training venue,

we'll meet the captain who'll lead you.

- For the whole four months? - Yes.

- Seriously? - I'm looking forward to it.

- We'll get going. - Yes.

(Who will be the captain to be responsible for Iron Girls?)

We're participating in a triathlon.

Don't you feel nervous just by thinking about it?

- Yes. I think it will be fun. - Do you want it to start soon?

I get excited.

I won't be able to sleep the night before the competition.

That may be the same for me too.

- But that won't be like... - The nervousness...

- is a positive nervousness. - Yes, thrilling.

- I'm an ENFJ. - Me too.

- I'm an ENFJ too. - Are we all the same?

- I'm an INFJ. - Oh, really?

I can see your face in real-time.

Your face is turning red, then normal, then back to red again.

When we ask you a question, your face turns red.

For real?

- Don't look at me. - I'm sorry.

If you look at her, she turns red.

(Don't focus on me.)

(She's shy.)

(So In Ah was qUiet throughout the whole journey to the venue.)

It's fun to listen to your conversation.

- Why aren't you joining? - I get immersed in it.

- Join. - It's not that.

I'm not good at interrupting others to join the conversation.

That's why I keep qUiet.

Is that why?

That's so funny. Then let's make sure we ask her.

What do you think? How about you?

- What do you think, In Ah? - Stop it.

- Don't do that to me. - She can't bear getting attention.

Then In Ah, when you want to say something,

- you should raise your hand. - Okay.

Yes.

If there's something you want to say, raise your hand.

- So... - Her hand isn't raised yet.

She didn't raise her hand.

(Looking forward to In Ah making a presentation)

That's cute.

I slightly blushed, but it's okay now.

Where are we?

What's this place?

- What's this? - It's definitely a gym.

- I don't want to get off. - Get off. It's unbelievable.

(The first place Iron Girls will train...)

(is filled with steel equipment.)

(A gym in Changwon)

(What's the first training for Iron Girls?)

- How shall we sit here? - We can sit like this.

(Wearing the right clothes before the training begins)

(Feeling tense now that it's really beginning)

I feel so nervous.

I feel nervous. When is the captain coming?

Is the captain someone we know?

- Is the captain someone famous? - No way.

(Their captain is coming.)

(The one who boasts sturdy leg muscles...)

Here he is.

Hello.

- Goodness. - Come on.

(Their captain is coming.)

(The one who boasts sturdy leg muscles...)

- Hello. - Goodness.

- Come on. - Oh, my.

(Who's the captain that makes everyone cheer?)

For real?

- Hello. - That's a real instructor.

For real?

(A former UFC player Kim Dong Hyun)

(A great physique)

(Stun Gun Kim Dong Hyun)

(He finished a race today.)

(The birth of the Iron Captain who will lead Iron Girls)

(Captain Kim is here.)

- We're dead now. - Hello.

- Hello. - Captain.

(Looking forward to him doing his main job)

- Captain. - Yes.

Was it your first competition today?

That's right.

(He finished the race on the first try.)

Did you apply something to your lips?

I'm fine. Mentally I'm fine,

but physically I got tired. That's why.

I'm just fine.

I just began to learn,

and those who are learning something are the best teachers.

Rather, real masters...

They can't understand us.

Right, they might not. They can say, "Why can't you do this?"

What made you...

try the triathlon?

Many people say it's very tough,

so I just wanted to do it.

- Since everyone says it's tough. - Yes.

So I thought it was awesome, exactly.

I want to do it more when others say they can't.

A triathlon will make you experience a lot of things.

When I was a professional player,

I didn't understand when people said they got a cramp on the legs.

I didn't understand why.

However, doing a triathlon,

- You got a cramp. - I almost got one swimming today.

I almost got one running, so you need to control your body.

But I can give you confidence.

I started swimming only two months ago.

- Really? - It's been less than two months.

While swimming today, I talked to myself.

- What? - I was talking while swimming,

- "This is so easy." - Really?

Yes.

Now I'm getting warmed up.

This is so easy.

It's easy for me.

(He says it's easy, but the truth is...)

(Breathing hard)

Someone was in front of me.

(He got tangled with someone ahead of him.)

(His swimming cap was taken off.)

(His first try for a triathlon wasn't easy at all.)

I have a question.

You're an athlete.

So it was easy for you.

We're real beginners,

and we don't know how to do it.

You say, "We can't do it because we're not athletes."

But once you see this person,

you won't say it anymore.

It's someone who participated in a triathlon.

Let's meet her now.

(Let's meet her.)

- Hello. - Hello.

- Please have a seat. - Our senior.

(Someone who tried a triathlon with a small physique?)

(She finished a triathlon for 15 times.)

(She finished the race today with ease.)

(Triathlon Player Kim Na Hyun)

- She participated today. - Did you get in the top five today?

Yes, I came in third.

- In third? - Yes.

In the aged 30s, the most competitive group?

That's amazing.

Have you liked sports all the time?

I didn't like sports in the past.

After I started working, I wanted to relieve the stress.

That's how I started playing sports.

Then I thought I wanted to finish...

a 10km marathon.

After finishing my first race,

I loved the valuable medal I haven't achieved so far.

I think that's what made me run until now.

It gives you joy.

- But we know nothing about it. - I see.

How much do we need to practice...

to finish a race?

I wouldn't say how much.

I think having an experience is what matters.

It's called "open water."

As you swim in open water...

with many people swimming around you,

you might hyperventilate.

Hyperventilate?

Other people might hit you while swimming...

- or hit your face. - Then you suddenly breathe like...

(It's hard to secure a clear view in open water.)

(To make matters worse, as many people start together,)

(your swimming goggles get taken off by hands and feet of other people.)

The moment they dived, his goggles were hit by the other's foot.

I heard they practice to prepare that too.

(That can happen to us.)

Let's say your swimming goggles were taken off...

- and you don't know where. - You just need to swim like that.

That's my expertise. I'll let you know goggles that wouldn't go off.

- I will... - Nice.

I think equipment matters.

- Right. - Equipment matters.

Yes. That's true.

- You need good ones. - It's because masters...

just tell you to endure.

But a good one wouldn't be taken off.

And I know swimming goggles with a clear view.

It's harder when you can't see well with your goggles misty.

I know one that wouldn't get misty, has a clear view,

and wouldn't get taken off even when you dive.

Is there a suit you can take off at one go?

A suit that can be taken off easily.

There's one. That's important too.

- A suit really matters. - A suit is really important.

- Is it? - A suit is so important.

When a suit feels too tight, you can breathe well while swimming.

So you need to adjust it well to your body.

I know someone...

- who specializes in fitting a suit. - To find the right size?

Don't worry about it.

I wonder if you're doing a business related to a triathlon.

- No, I'm not. - Are you preparing one?

Since I'm a triathlon beginner,

I search for a lot of information.

So don't worry about equipment.

If you just do your best, I'll help you finish a race.

What's the charm of the triathlon, as you think?

- You will see if you do it. - You can see only when you do it.

In fact, in your job,

it's hard to get acknowledged.

But when you finish a triathlon,

you can acknowledge yourself.

That increases...

your self-esteem very much.

Although you're troubled...

or stressed out...

- In your life. - Yes, in my life.

I think, "I'm a woman who completed a triathlon."

"And it's nonsense if I can't overcome this."

- That's why. - Yes, that's what I feel.

So it makes me keep challenging myself.

The more I hear you say, I can't imagine...

myself completing a race.

It just sounds like someone else's business.

I will pull all the strings I can...

to organize the best team of trainers for you.

I will make you complete the race.

I will help you.

Let's all meet in Tongyeong and finish a race with a smile.

- Let's set the goal. You can do it. - It sounds awesome already.

Thank you.

- It will be so touching. - I can't imagine it, though.

(They gird up their loins to be Iron Girls.)

First, you need to build basic physical strength.

- Yes. - Let's examine your strength.

May I test your strength?

- Today? - Yes, right now.

- Today? - We need to see...

if you'll be able to finish a triathlon.

(Until the race in October, they have only 4 months.)

(Our goal is to finish a race.)

(They need to build physical strength in a short time!)

(It's important to see the current situation of Iron Girls!)

(Jin Seo Yeon, Uie, Park Ju Hyun, Seol In Ah)

(Examination of Iron Girls' basic physical strength!)

You'll be tested on five categories in total.

The first test is on muscular endurance.

(Excited)

It's on endurance.

- Muscular endurance is about... - How much you endure.

how long you can use your muscles.

Athletes have good muscular endurance.

When ordinary people use strength, they can't recover soon.

But athletes recover after they breathe and shake their bodies.

(Athletes have a quick recovery due to good muscular endurance.)

We need to build that.

There's one fearful exercise for it.

I'm scared.

For today's test,

it's something called "burpee test."

(She hates it.)

Burpee?

It's a whole-body exercise,

aerobic exercise, and muscle-strengthening exercise.

(The burpee test is well-known for being an extremely tough workout.)

I will show you how to do it for five times.

One,

- That's amazing. - two...

We sometimes read a book doing this.

You can do it comfortably like this.

When something falls under a furniture,

you can look at it this way.

You can do it like this.

Your stomach and chest should touch the ground.

If your chest doesn't touch the floor, it doesn't count.

- It doesn't count? - No.

For today's test, for three minutes,

we'll see how many burpee tests you can complete.

It's to check where you are now.

- For three minutes? - Take a rest if you want to.

- It's about how many you can do. - It's about how many you can do.

- We'll do it all together. - Don't push yourself.

Let's just see how many you can do.

Don't overdo your strength. Just do what you can.

You don't have to rest too.

Let's do it for three minutes.

I'll do it accurately.

It can be tough for you. I'm telling you.

Three minutes can be really long.

Here we go.

(Iron Girls want to do a triathlon.)

(What's their current physical condition like?)

- Are you ready? - Yes!

Ready, set,

go!

Good.

(They started smoothly.)

Am I doing it right?

You're doing it great.

(In Ah is getting ahead quickly.)

It's nice to clap your hands like Uie does.

It's nice to clap your hands.

(Uie keeps a correct posture.)

Thirty seconds have passed.

(30 seconds have passed.)

Okay.

(In Ah is smiling until now.)

(Meanwhile, two of them are getting exhausted.)

Clapping.

It's amazing. She's moving like a machine.

(The one who surprised Dong Hyun)

Uie hasn't taken a break.

(A standard of burpee test)

She was a swimmer for a long time, so she's good at aerobic exercise.

(Showing accurate movements as a former athlete)

(Neat movements without an unnecessity)

(And right beside her,)

(In Ah is moving with the same speed she started.)

(A nip and tuck match)

One minute has passed.

- What? - You're doing great.

You must be lying.

Aren't we done yet?

This is killing me.

All right.

You're doing great.

Okay. You can do this.

(By the time everyone is getting exhausted)

Uie hasn't taken a break yet.

She's doing it with the same speed until now.

- She's amazing. - Uie is crazy.

Good!

Are you a machine or what?

(She's moving with the same pace.)

- She's taking off her shoes. - This feels uncomfortable.

(Eager)

(Making a spurt at the last minute)

- Okay. - What's this?

I can't move.

You can take a break if you feel tired.

You have 15 seconds left.

Let's make one more move.

Ten, nine, eight, seven,

six, five, four, three,

two, one! That's it!

That's it!

(Screaming)

(A mess)

Seriously,

you're amazing.

I don't think I can do a triathlon.

You can ride a cycle in this condition.

(What are you saying?)

But I...

(Looking the other way)

Among martial arts players, there's a former swimmer.

Swimmers surely...

are different in a physical aspect.

(Different)

- Uie moved almost like a machine. - Exactly.

She kept moving at the same pace.

(She was like a burpee machine.)

You're the best.

She didn't take a break even once.

- If you take a break, it's harder. - I know. I took so many breaks.

I thought the same thing, but I couldn't help it.

First, I'll announce the fourth place.

(Time to announce the ranks)

- Seo Yeon is in the fourth place. - I'm the last.

- She did 29 burpees. - Really?

- You did a good job. - How many did you do?

- You did a lot. - The one in the third place.

She did it well, surprisingly.

- Ju Hyun comes in the 3rd. - The 3rd place?

I thought you wouldn't do many,

but you did it in your own way...

and did 32 burpees.

(She completed 32 burpees by making a deep bow.)

And the second place goes to In Ah.

(In Ah comes in 2nd place.)

She did 38 burpees.

How many did you do?

Well,

(She was so fast in the beginning.)

she was passionate enough to take off her shoes.

I expect her to improve fast...

as passion enables improvement.

(Passionate rookie In Ah)

And the first place...

- The best ever. - You were like a CrossFit player.

Uie did 40 burpees.

(The 1st place goes to Uie.)

You're the best.

You're really awesome, Uie.

If you had five minutes,

you'd almost do 70 to 80 burpees.

You kept clapping your hands, making standard movements.

It's not easy to do it without any break.

(Beginning, middle, end)

(Throughout the 3 minutes of testing)

- You were really good. - You looked awesome.

(The one with the most muscular endurance)

(Jin Seo Yeon, Uie, Park Ju Hyun, Seol In Ah)

The second test is for agility.

What does agility have to do with a triathlon?

As I experienced a triathlon today,

whether you're in the water or on the road,

various situations can happen.

To quickly tackle those situations,

you really need agility.

So I'll test you to see...

your basic agility.

It's called ladder training.

You can do a lot of things on a ladder.

I have over 100 exercises...

- you can do here. - Really?

I'll see if you can imitate basic movements...

and how fast you can pass them.

If you don't do this well, it will look like an old comic dance.

I know. It looks weird.

Here we go.

Now, you need to watch this carefully.

(Today's test is the side three-step.)

- You start here... - We'll watch you.

One, two, three.

One, two, three.

You go into one cell twice.

You enter the same cell twice.

(Side three-step is taking your feet in and out of a ladder shape.)

(Focused)

- You look awesome. - You can run too.

(Quite quick foot moves)

We're doing these things all the time.

(Boasting)

Who's going to try it first?

Agility.

She's good at dribbling.

- Futsal. - No, I'm not.

- Try this. - You play soccer.

- Go ahead. - It looks like dribbling.

- Our soccer player. - I'm not a good soccer player.

Soccer players do this training the most.

I know. I've seen them doing this training in videos.

(She tried the foot movements.)

That's correct.

Go.

(She begins to move in earnest.)

(Marveled)

Wait.

(Shocked)

Wait a second.

(In Ad said she couldn't do it.)

Wait a second.

- Did I do it right? - Yes. Wait a minute.

- Wait. - Did I do it like a comic dance?

- No, you didn't. - You're so good.

- I was surprised. - It was so funny.

- It wasn't... - I won't do this.

It wasn't a comic dance.

First of all, I couldn't see your feet moving.

(She made one soft step...)

(and like a bird...)

Wait a minute.

(and flew away.)

(In Ah's record: 6 seconds 29)

Then why are you laughing? I look funny now, right?

You need to look funny for this.

Why does it look so funny?

(For some reason, they were laughing out loud.)

What kind of person is she?

It's because In Ah,

you said, "I don't think I can do this well."

(Totally different)

and you were like this.

(A totally different woman in front of the ladder)

- That looked so funny, In Ah. - That's what I'm saying.

You have a great posture and all.

I mean, she does it like a professional athlete.

- "I really can't do this." - She said she couldn't,

When In Ah plays sports,

her face changes.

(Totally different from usual Introverted In Ah)

(Sports In Ah)

Wait. In this cell?

- Yes. - She can do it no matter what.

- She has such long legs. - Nice.

Good job. Great.

Go to the end.

It's because of her shoes.

- She moves so lightly. - That's true.

(Seo Yeon's record: 13 seconds 22)

I can see that Seo Yeon has been doing weight training.

Weight training instructors say,

"You need to feel the simulation on your muscles."

As that's familiar with her body, when she was doing this,

she strains her muscles instantly.

(Straining leg muscles)

She got used to building her muscles.

You're right.

- But you should do it this way. - I don't do those workouts.

(Jin Seo Yeon, Uie, Park Ju Hyun, Seol in Ah)

Everyone, this time, it's not tough.

I'll test your flexibility.

(Flexibility)

I really have no flexibility.

- You don't? - No.

Let's check it out first. We need to see how bad you are.

Do just as much as you can.

She can do it.

- Does it hurt? - It's 5.6cm.

- Uie, go. - Here you go.

(Uie has long arms and legs.)

It's 12.8cm!

(The eldest Seo Yeon)

Push ahead.

(Surprised)

(Stunned)

It's 19.2cm!

(Currently in 1st place, Seo Yeon: 19.2cm)

In Ah has a really flexible body.

But I don't think I can do this.

Okay. You're good.

Oh, wait. We start from here.

(She became a Worrywart once again.)

Let's go.

If you are flexible enough to make this,

- you literally have all. - But I mean...

Start!

(Opposite to her concern at first,)

(her body is bent down perfectly.)

(Shocked)

My lip is split!

It's 27.6cm!

- I'm so shocked! - Gosh!

- She has a good body balance! - My lip is cut now.

She said she's good at nothing,

- but it's the opposite! - It's 27.6cm!

She's just born that way.

- That's what I mean. - Seriously!

- It's crazy. I was shocked too. - How can she...

Can you move up your leg while standing up?

I used to do it often,

but haven't done it recently.

(She tries, full of worries again.)

I recently haven't done it. Seriously!

That's it.

(Are you sure you are not confident, In Ah?)

- It's perfect! - How...

This way!

- You're like a ballerina! - How could she...

That was... Wait a second.

You were good at these when you were a kid?

I liked these, but never thought I was good at.

How can I explain this?

Considering all the aspects,

she has the best body balance so far.

(The genius type with a good balance)

(Jin Seo Yeon, Uie, Park Ju Hyun, and Seol In Ah)

(She has the greatest record so far.)

(In Ah shows the best performance for now,)

(but Seo Yeon doesn't meet the expectations.)

The next test is the muscular strength tests.

(Seo Yeon needs to make use of this opportunity.)

There are big three exercises. Deadlift,

bench press, and squat are those.

We count this.

Men who work out often, do over 500 for these.

When someone lifts over 500kg from these,

we consider they've been working out quite long.

(For the average Korean woman, it's around 80kg.)

We will start checking your record from Seo Yeon.

If you lift over 50kg, that's more than good enough.

(They start with the deadlift.)

How long you've been handling physical training?

I guess it's over 15 years so far.

We will see her skills with over 15 years of experience.

Focus. Slowly!

Just leave it if you can't handle it.

Just threw it. You shouldn't hold it when you can't!

- Nice! - Okay!

She's so cool!

It's 35kg.

(She challenges 35kg of bench press.)

I will support you.

It's 60kg.

(Squat)

- Okay! - She's awesome!

Show your pose!

(I'm the muscle queen of Iron Girls!)

I can easily see she's worked out for so long.

I haven't done any lifting.

Me either.

If you do these suddenly, you will probably get hurt.

So I think we should stop with squat for now.

With your legs!

(Deadlift: 45kg, 45kg, 50kg)

Okay!

Oh, okay!

- I can't do this. - No, you can't.

How did she lift this?

How did you do that, Seo Yeon?

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

(In Ah still records the top.)

So, I believe we finished the warm-up, right?

- Yes. - I see.

Here we have the real final test.

Today, we will test one of the actual sports of the triathlon.

Let's move on to take the test.

But we are all worn out.

Yes, that's how it goes with triathlon.

In triathlon, we take the test when tired.

Captain Kim, you look also tired. Am I right?

You see the sweat here, right?

(The Iron Man is also tired.)

After all of this, I'm exhausted too.

But as this is our final test,

- let's move on. - Let's go!

(What will be the final sports for the test?)

(Goodness)

(My gosh)

- Are you ready, Captain Kim? - Me? Of course.

(All take in the car with the sound of moaning.)

It looks like it's going to rain, guys.

We should wear some thick clothes.

So, what should we do, then?

- It's still a secret? - Sorry?

- You will see when we arrive. - I got it.

(Where have the Iron Girls arrived?)

I guess the rain has stopped for us.

- Gosh. - What's this all?

- Cool! - This is really cool.

- I'm so thrilled. - You've never been to a stadium?

- I've never been. - Never.

Really?

(A long track)

(The Changwon Civic Stadium)

(What kind of tests will be taken in this huge stadium?)

We are here in a stadium.

Some may have already guessed when seeing this stadium.

It's the most important part of a basic physical test.

It also checks your cardiovascular endurance,

the inevitable part of the triathlon.

Cardiovascular endurance is...

- I hate it more than anything! - Cardiovascular endurance is...

he hardest for all athletes.

It's also very hard to maintain the same record.

Because just a short period of rest...

will change everything.

Through this, we can see who is the most sincere,

consistent, and diligent.

Someone with good cardiorespiratory endurance takes all in the long run.

So, we will measure each one's cardiorespiratory endurance...

from now on.

As I always said,

I invite the best experts and legends for each part.

- Someone's there? - You invited already?

Yes, there's someone there.

- Seriously. - You really should do your best.

I also wanted to ask a lot...

when I met this person.

The legend in marathon.

Let's welcome the manager, Kwon Eun Ju!

- Gosh! - Oh, my!

- Hello! - Nice to meet you.

- My goodness! - Nice to meet you.

I was a former long-distance runner.

Now I work as a manager of a running club.

- It's nice to meet you. - Nice to meet you!

(She's a living legend in the Korean marathon.)

(She was a former national marathon runner.)

You are so cool!

In the women's marathon,

your record was not broken for a long time.

It lasted for 21 years.

- I got a goosebump for real! - I had that record.

- It's not broken yet? - There's a new record now.

It was replaced in 2018.

Yet, it still lasted for 21 years!

That's amazing.

I really should do my best.

Would you tell us what test will be taken today?

Today... Actually, I don't know how good you can run now.

- Yes. - So...

I can't take the details of cardiovascular endurance...

while you run around 1 to 2 kilometers.

I know it will be hard, but you need to run 5km.

You need to run 5km.

(The final basic physical test)

(Running 5km)

It's a 400m track.

- It's just a 400m? - So...

You need to run 12 and a half laps.

(The size of the stadium is so big.)

(After running all this track,)

(it's just a 400m.)

(They need to run 12 and a half laps to run 5km in total.)

(They should run 12 and a half laps.)

It's just a 400m track?

- How can we do that? - For me...

It's merely a 400m lap?

- We should run 12 and a half laps. - You ladies...

have tried...

running for 5km before?

Never?

(Have you run for 5km so far?)

I haven't.

I have never done it before.

- So, not in this kind of a track? - No.

(I see.)

Then, it'll be good if you show me your best at least.

- I may cry doing this. - Manager Kwon,

- how long does it usually take? - For those who run as a hobby,

it takes around 35 minutes.

- Sorry? - So it should take seven minutes...

per kilometer.

(To finish 5km in 35 minutes, they should run 1km in 7 minutes.)

That means...

Do you mean per each lap?

I have no idea...

what she means.

(The basis of running)

(What is a pace?)

(It's the time one takes to run 1km.)

Let's say it took seven minutes.

It took 7 minutes to run 1km.

When you watch the clock and it takes eight minutes,

you can assume it'll take 40 minutes to finish all.

As the feeling and the actual record have a gap,

you should check your pace.

So, it's important to check your pace.

(Checking pace is very important to maintain good records.)

If you finish today's running within 40 minutes,

I think it's really good.

The nice-minute pace is also not bad.

I will let you know the pace per lap.

- I see. - You're running at this pace!

Like this.

- Good. - Let's do as I said.

We need to learn the basic posture.

I also need to learn.

Tightening your stomach is a default.

Arms stay on the sides naturally.

And lower your jaw a bit.

Then, stare 10 to 15 meters forward.

- Like this? - You just need to look downside.

If you just see the front, there are too many things to take care of.

- Yes. - That makes you tired.

It will burn out your energy, then.

How should we breathe?

In terms of breathing...

Actually, in many textbooks,

the rule is to inhale twice with your nose...

and to exhale twice with your mouth.

Running has its own trend.

So, breathing with your nose is important nowadays.

It has its own merit,

- especially with the dust issue. - Yes.

It prevents harmful dust...

from entering our lungs.

But when beginners just listen to it...

and follow that,

- they will be exhausted easily. - That's right.

- Right! - I won't be able to do that.

So, what matters the most is to keep your pace and get used to it.

When you feel confident with that pace,

then try using that method.

Until then?

Use both your nose and mouth.

- As I prefer? - Yes.

Use as you please.

- There's no answer in running. - That's right.

Each individual has its own preferred way.

All you need to do is search for what's best for you.

- I got it! - Yes.

This way. Slowly. One,

(To prevent any injury)

two.

One, two, and three.

One and two.

(Once they finish the basic warm-up well...)

One and two.

- Yes. - This is enough.

- You started sweating, right? - Yes, I did.

So, let's finish this...

- and start running. - Okay!

Can I really make it?

Use the restroom if you want.

- Yes, I will. - See you later.

Should I use it beforehand?

- There it is. - Yes.

It's suddenly raining heavily.

(They undergo harsh hazing with heavy rainfall.)

- I'm nervous. - That's okay.

(Will they be able to run well in this weather?)

- Gosh, I feel so nervous. - Shall we give it a try?

Take a deep breath. We can do it!

(The members feel nervous before the 5km run.)

Gosh, I feel so nervous.

I had no experience at all.

(Actually, the Iron Girls...)

I have never done a full 5km run before.

I have only done it in intervals.

All of the girls said they haven't done it before.

"What? A 5km run?"

A 5km run to me...

is a distant story from me and someone else's story.

I do enjoy walking, but even with that,

it's only up to 2 to 3km.

I had no idea what to expect, and I was scared, to be honest.

I felt so nervous. My heart...

was about to burst.

Even though it wasn't an actual race and it was just a test.

(The 5km run test)

All right. We'll start.

One, go!

Go!

How do you feel?

- I'm fine. - I'm okay.

You can speak as you run.

Let's run with enough energy to speak.

(The eldest runs while taking care of the nervous younger members.)

I can't speak because I feel so scared.

- You don't have to. - I might lose my strength.

Don't speak.

(The Iron Girls run through the rain.)

(From here,)

(to here)

(The run half a lap and the 12 lap count begins.)

(They run in a single file as they match each other's pace.)

They must be really afraid about running.

They're running really slowly.

You can give up in the middle or become slower.

The pace is too slow right now.

- It's too slow? - Yes. It's too slow.

The pace you're running at...

will take nine minutes.

That's a walking pace!

(The 12 lap count begins.)

(Uie was running from behind.)

Run at your own pace!

(As soon as she hears the coach, she moves out to the 2nd lane.)

(Uie runs like the wind.)

(In a flash, she heads in front.)

(Stamina Queen, Uie)

During the test earlier,

she did really well with the burpee test.

Her cardio is great.

She has a great running form, and she has a good rhythm.

Right. And I get the feeling...

that Uie is someone who can run even faster.

It's the first day today and she feels a bit anxious.

- She hasn't done it before. - She's controlling herself. Right.

(It feels like she doesn't know her own pace yet.)

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

Great.

(All of them complete 1 lap with Uie in the lead.)

(Uie)

(Uie paces forward.)

(Iron In Ah catches up in no time.)

(While running in the third spot,)

(she brings up her speed.)

- I'll move ahead. - Okay.

(She takes off her jacket.)

(In Ah, Uie)

(In Ah moves up to the leading group while following Uie.)

In the lead, there's Uie...

In Ah?

- In Ah? - Yes.

(The Sports Genius chases after Uie.)

(The distance between them is getting closed.)

(Iron In Ah catches up with a great speed.)

I've been feeling this for a while.

- In Ah is amazing. - Really?

She has strong muscles. Her reflexes and agility...

are very good too.

She's flexible too. She has all the good traits.

It seems like she was...

- born to be an athlete. - Right.

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

There are ten laps left.

Ten laps.

(In Ah, Uie)

You're running at the pace of 6 minutes and 30 seconds.

You're doing great.

- That's really fast. - Right.

(The 6 minutes and 30 seconds pace)

(Good pace that has a good chance of finishing 10km in less than an hour)

(The track is filled with just panting...)

(and the sound of busy feet.)

(Ju Hyun, Seo Yeon)

You can just keep this pace.

- You're doing great. - Great.

Just keep this pace.

(In Ah followed Uie well for two laps.)

(However, from the third lap,)

(her speed slowly dropped.)

(Uie, In Ah)

(The distance between them got bigger.)

(Did In Ah stop in the end?)

(She tries running again right away.)

Gosh!

My ribs hurt.

Start running if your stomach feels better!

She lost her speed. She had to get the momentum.

Gosh.

(She feels severe abdominal pain.)

(She tries to catch her breath while walking.)

(Ju Hyun starts to pace forward?)

When I played badminton, people said they wanted to...

raise me as a badminton player.

When I did boxing, people said they wanted to...

raise me as a boxer. I've been hearing these things.

I had a sense of pride because of that.

(Ju Hyun had a sense of pride with sports.)

In Ah is very athletic.

Seo Yeon had been consistently working out.

I could tell just by looking at her.

Uie enjoys doing sports,

and she knows the basics as she has a lot of experience.

I thought about myself,

and I realized that I was someone...

that hadn't done anything consistently.

I got disappointed in myself.

And for the first time,

I got competitive with myself.

(Uie, In Ah, Ju Hyun)

(She ran without stopping and closed the distance between her and In Ah.)

(Ju Hyun goes past In Ah in the end.)

Hold on. Right now...

- Their places have changed. - Right.

- In Ah moved down. - Really?

(Captain Kim looks surprised as he has never seen this from Ju Hyun.)

(In Ah, Ju Hyun)

I really wanted to give up, but I thought, "If I give up,"

"the life I have lived will go to waste."

I went that far with my thoughts while running.

Awesome!

She runs well.

(Ju Hyun shows a different side of her from the previous tests.)

They all have different strengths.

- Good luck! - Great!

Ju Hyun has it.

(Ju Hyun)

(Sighing)

Oh, gosh.

(Sighing)

(Here's another person fighting against herself.)

How was Seo Yeon during the test?

She did a lot of personal training, so she has good muscular strength.

She's the best with that by far,

but she did say she struggled with cardio.

(Current pace: 8 minutes and 10 seconds)

(Uie who is in the lead is keeping her 6-minute pace.)

(Seo Yeon, 4 laps, Uie, 5 laps)

(In the end,)

(Uie came right behind Seo Yeon.)

I was in a situation where I could outrun Seo Yeon.

I thought that she might give up because of me.

That was why I was a bit torn at first.

"Should I not outrun her?"

(Uie is running with a concern of her own.)

(Uie outruns Seo Yeon.)

(Uie, Seo Yeon)

(There's a one-lap distance between the two of them.)

Great.

- Five laps. - Great!

I thought about not outrunning her.

But I would be stopping myself from doing something I can,

and this was a test too.

I had to show what I could do...

for the coaches to evaluate me.

(Seo Yeon, Uie)

Uie outran me.

"Whatever. Go your way."

"I'll stick to my pace."

I thought that it would affect me...

if I see the other members run,

so I just...

looked 15m ahead of me when I ran.

(Iron mentality that does not get affected even after getting outrun)

(Uie picks up her pace after outrunning Seo Yeon.)

(Who's the next target?)

(It's In Ah!)

(In Ah, Uie, Seo Yeon)

(She uses her long legs to get closer to In Ah.)

(Looking)

- Good luck, In Ah! - Gosh, you're amazing.

Good luck, In Ah?

(What's up with her?)

Your pace is amazing.

Uie is amazing.

If your upper body feels stiff,

you can bring down your arms and shake them.

- That's it. - You have four laps left.

Great!

Gosh, four laps left.

(Ju Hyun, 7 laps)

(Uie, 8 laps)

(Steady form...)

(and stable breathing)

(She has already reached Ju Hyun who is in 2nd place.)

(Her stamina feels a bit scary now.)

(One step...)

(and another)

Let's make sure to get to the end.

Okay.

(Uie quickly moves away after sending her support.)

Uie outran each of them.

Gosh, Uie.

- Three laps now! Great! - You're almost done.

There's 1km left.

Focus!

- She's keeping the same pace. - Great.

- The 5km run is hard to do. - Right.

She's amazing.

She's consistently keeping her pace for all laps.

Right. She's doing well to keep a consistent pace.

(She's keeping a consistent pace.)

She's doing well to use the midfoot strike.

Gosh, she's amazing.

(She's using the midfoot strike well with her running form.)

(Midfoot strike?)

(Using the middle of the foot to land on the ground first...)

(can reduce the impact the body feels while running.)

(In Ah's running form...)

(is the heel strike with her heels landing on the ground first.)

(Heel strike)

(It's similar to the walking form and can be adapted to easily,)

(but the body can easily get tired from the heavy impacts.)

(Uie has kept a consistent pace like a machine.)

I think Uie is picking up her speed.

Great.

It seems like she's getting faster.

(She's getting even faster.)

She's definitely a former athlete.

(The Stamina Queen's last spurt!)

She's amazing.

(The Stamina Queen's last spurt!)

Great! One lap left!

- Great! Just one lap left! - Great.

(There's just one lap left.)

- One lap left! - It's your last lap!

(Uie)

(There are 400m left.)

She's amazing.

One lap left!

I got my head up as soon as I heard, "One lap left!"

I really wanted to get my head up and see my members.

I really did.

(She checks where her members are.)

I wanted to finish first...

and support them.

(Uie picks up her speed with just that thought in mind.)

(The two are two laps apart from each other.)

Good luck, Seo Yeon!

- Good luck! - Good luck!

(The two carry on while supporting each other.)

(Uie, Seo Yeon)

(Uie heads to the end after a short moment of support.)

(Uie heads to the end after a short moment of support.)

I don't think Uie will fall behind even toward the end.

She won't. She can carry on.

She's keeping a good rhythm.

Uie just needs to learn how to cycle and she's all set.

(The ace of the Iron Girls runs calmly...)

(while earning the captain and coach's trust.)

She's amazing.

You're almost there!

(Uie)

You're almost there! Great job!

(Uie heads to the finish line.)

(The first run in the heavy rain)

(Uie does her best until the end.)

- Good! Slow down slowly. - Awesome!

- Great job! - Awesome!

(Uie showed her potential with her first 5km run.)

You got 31 minutes and 42 seconds.

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

(Average pace: 6 minutes and 20 seconds)

You got 31 minutes and 42 seconds.

(Uie finishes the 5km run first.)

(A moment when a mixture of emotions flood in)

Great job!

You were amazing!

You keep your pace really well!

Why were you acting so weak?

- You were amazing. - Awesome.

(Even with the flooding compliments of the captain and coach,)

I mentioned this earlier.

You ran slower at the start.

(her eyes are fixed on her members.)

It means you ran 10km in just 60 minutes.

- Great! - I did it at around 55 minutes.

You ran at a similar pace as me.

You were amazing.

Good luck, Seo Yeon!

- All right. - Focus!

- Good luck. - Two laps!

Two laps.

You have one lap left! Great!

That's amazing.

- You're doing great. - Good luck!

One lap left! It's the last lap!

Great job. You're doing great.

You're amazing!

- You can do it with a smile! - It's the last lap.

- I can't smile. - She's keeping the same pace.

(I can't smile.)

(She's breathing heavily more than anyone else,)

(but Ju Hyun continues to move forward without stopping.)

(Because of the pouring rain,)

(she's running without being able to keep her eyes open.)

Ju Hyun's upper body has started to sway a lot now.

(Her upper body is swaying drastically due to exhaustion.)

- During the test earlier, - You were worried about her.

she fell behind. That was why I thought...

she was going to give up in the middle.

- But she's in second place. - She's going to...

gain some confidence from this.

Just 100m!

(There's just 100m left until the end.)

- Just 100m left, Ju Hyun! - Good!

You're almost there!

She's amazing.

- She kept the same pace. - She has a good pace.

She's amazing. Her ankles aren't in good condition too.

- You're amazing! Awesome. - She kept it with 7 minutes and 20.

Great.

Great! Until the finish line!

- You're picking up your speed! - You're getting faster!

- Great! You're amazing! - Okay!

(Groaning)

(Panting)

You got 36 minutes and 20 seconds.

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

(Average pace: 7 minutes and 16 seconds)

- Great! - Slow down.

- You're done! - No! You're done!

Where are you going? Come here.

I didn't even know where I was supposed to finish.

Until Uie told me I was done,

I didn't realize that I finished the run.

While I was running,

I wanted to give up because it was so exhausting.

While Uie was running past me,

- Let's make sure to get to the end. - she wanted us to get to the end.

She left with those words,

and that suddenly gave me a burst of strength.

"I can do this."

I had this thought because of that.

(Ju Hyun finished the run thanks to Uie's support.)

Don't sit down!

You can't sit down. Your legs will give in.

Rinse out your mouth. Hurry!

(Her legs give out as it's the end of the run.)

- Rinse it and spit it out. - She's amazing.

You can't walk tomorrow if you sit down. Get up.

- How am I supposed to stand? - What?

You did well.

This is crazy.

I heard you didn't stop at all.

(Ju Hyun now has an older member that can hold her hand...)

(when she feels exhausted.)

You won't be able to walk if you sit.

(Swaying)

You're amazing, Ju Hyun.

I hate running so much!

I hate it so much!

I hate running so much!

(You are witnessing In Ah's moment of hating running.)

I just hate it.

Gosh.

Let's take it slow.

(She keeps reminding herself to take it slow.)

Take it slow.

Take it slow.

(In Ah runs her final lap.)

(Sighing)

I really hate it.

Don't stop.

Just don't stop.

Please.

You have 100m left!

Don't pick up the pace! Just come in!

(While going through pain during her run,)

Great!

(In Ah kept saying she hated running.)

Relax. Run comfortably. Just come in like that.

- Until the end! Great! - Okay!

(A happy smile appears.)

You got 37 minutes and 6 seconds.

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

You did well!

Don't sit, In Ah.

Rinse your mouth.

- You walked during the run, - You're amazing.

but you still did a great job.

Spit it out.

You're amazing!

(Uie takes care of the younger member.)

You're all amazing.

- You all finished this? - You all are great runners.

- Right. - She's the best!

(Uie is the best!)

- Ju Hyun is the best too! - Amazing. We all did it?

- Gosh. - You all did it.

(There was someone we forgot about.)

(Seo Yeon is left alone in the vast stadium.)

(She definitely has the heart of a winner,)

(but her body won't help her.)

(Groaning)

I kept brainwashing myself.

"If I stop, my child will stop breathing."

(You went that far?)

"If I don't win the gold medal,"

"I will get shot down."

(Get shot down by who?)

"They are pointing the guns at my family members."

I imagine all sorts of things...

to make me finish the run.

(Checking)

(Everyone else is done except for Seo Yeon.)

(I'm the only one who hasn't finished?)

(Final booster on)

(Seo Yeon runs with everything she has left.)

She's doing her final run.

Okay.

- She's speeding up. - Okay.

Seo Yeon, maintain that speed.

You can do it!

Let's go, Iron Girls.

She's so cool.

Let's go.

It's 38 minutes and 17 seconds.

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

(Average speed: 7 minutes 39 seconds)

Seo Yeon!

Seo Yeon, don't sit down.

- Okay. - Don't. Your legs will give out.

Walk slowly.

She is really amazing.

- You're all amazing. - She is really amazing.

I really wanted to walk.

I wanted to give up and lie down.

But I kept thinking that everything would end...

the moment I stopped.

There was no stopping or finishing it halfway.

That wasn't my option.

That was how I ran.

You all finished it within 40 minutes.

(Everyone completes the run in 40 minutes!)

Seo Yeon, we all finished it in 40 minutes.

- Thirty-eight minutes. - For the first time.

This is crazy.

- She's so cool. - You're so cool.

You did it.

She's so good.

Great job, everyone.

- We did it. - Good job.

- Really. - You should do it.

(Completing a 5km run for the first time...)

(confirmed their possibilities.)

Everyone was so happy.

You feel happier when people around you feel happy.

I like the feeling of my emotions multiplying.

When I was a swimmer, although we were technically a team,

I was jealous of those better than me.

But strangely,

we came together for a triathlon,

but we also became a crew as Iron Girls.

Since the moment I stopped thinking about...

beating the members...

Spit it out.

- You're the best. - Lean on my shoulder.

- You're really good. - It's over.

I thought, "I must love them a lot."

We have similar levels of stamina, and we know that.

But everyone tried their best and didn't give up.

If one gave up,

we might've lost our willpower halfway.

- But we all were considerate... - You can do it.

- to each other. - You can do it.

"If I stop, she'll want to stop too."

Everyone must've thought the same.

Actually, when I was offered this show,

I thought...

it was fine as long as I did well and did my own share.

I am proud of myself...

- for finishing it in 31 minutes. - It's 31 minutes 42 seconds.

But I'm even more glad that all four of us...

finished the race without anyone getting injured.

I even thought, "Is this the power of sports?"

("Is this the power of sports?")

We built teamwork.

I felt the team's synergy.

"Is this what I imagined?"

I felt that glee.

Sportsmen have the sort of comradeship.

I definitely thought we'd feel comradeship once we were finished,

but we felt it so quickly that it was embarrassing to show it.

I find it very fascinating.

I've never experienced...

something like this.

I mean,

- Mom. - I thought at least two would fail.

Everyone made it within 40 minutes.

Great job.

I'm so shocked.

I mistakenly thought you were workout novices.

I should make some calls...

- and make the training very hard. - No!

I mean it. Even if I had told you to run 10km today,

you would've done it somehow.

I do agree.

- Really. - And the most important thing...

is that you're all smiling.

You were very worried just now.

Now, you're smiling...

- with a sense of accomplishment. - She...

- Really. - Uie...

- You made it in 30 minutes. - I was so surprised.

This is amazing.

- You were so good. - That means 60 minutes for 10km.

Your record will be amazing even if you take part now.

(Outstanding muscular endurance and cardiovascular endurance)

You guys have huge potential for growth. Great job, guys.

Thank you.

- You worked hard. - Thank you.

- Yes. - Yes.

Please tell them the goal for running.

He and I discussed it.

- After 3 weeks... - "After 3 weeks?"

Three weeks? I want to enjoy today.

Didn't we do a good job?

- It even rained. - We...

We all made it in 40 minutes.

You ran 5km today.

So after three weeks,

you'll try it.

- Three weeks? - Yes.

(After 3 weeks,)

(what crisis will Iron Girls face?)

(Screaming)

(Shouting)

(Today's special training)

(A 123-floor perpendicular marathon!)

(Stairs of 123 floors?)

(Who walks up this building?)

(I've never climbed more than 5 floors of stairs!)

(You will climb them.)

(The nightmare of laziness?)

(No, the nightmare of stairs!)

(To the top of that nightmare)

(They climb and climb.)

(They end up on all fours?)

(They're insane.)

(Can they climb up 123 floors?)

(I want to give up.)

(You don't have time to give up.)

(Get up, it's time to swim!)

(Ace Uie, an ex-swimmer)

(Her body remembers how to swim?)

(She is incredible.)

(And an unexpected...)

(ace appears?)

(What kind of swimming is this?)

(She swims like a dog for a while.)

(When is she going to breathe?)

(Breathe!)

(Even In Ah whom they trusted...)

(never swam before?)

(But the real problem is...)

(Seo Yeon who is scared of even entering the water.)

(Can Seo Yeon overcome aquaphobia?)

(A swimming coach who came to save them)

(A swimming coach they never imagined arrives?)

(She is...)

(really here?)

(Who is the special coach that made the girls feel fluttered?)
