Thanks for this fascinating video. I follow Léon's performances for many years, but i confess i didn't realize the enormity of Léon's record last night. Thanks again for your explanations!

Peter Vanderkaay went 4:08.6 at the Michigan Open in 2008. It was an American record at the time and still the pool record at Oakland University I believe.

A little faster and I’ll start to think Leon Marchand is a mutant. To hold that speed and maintain those underwaters for 500 yards is a force to reckon with. / (Well done with the event history. Helps us appreciate the achievement even more).

Your enthusiasm is a pleasure to see. I hope your brain will digest and accept this performance;)

I thought I was watching a 3:59.99 for about half the race

Best swim analysis video ever. You said everything right and nothing wrong.

I agree. Leon showed the way and now coaches will learn the underwater to kids and one day these kids will break all the records.

MOST impressive was he took it out in 1:33! For the 200

I remember hearing back like 10 years ago Misty Hyman’s old coach say someone could go 3:59 kicking to 15 every wall. Thought that was a pipe dream then, but now…

Marchand is a fan of 4:02

Agree. The 5th stroke is now the most important stroke. It is the true differentiator and everyone needs to be working on it. It's always been who can pop up the furthest last usually has the lead, but in shortcourse the person who has the best underwater in every stroke will win, except for breast. Hell, just think, fly is now 4 or 5 strokes a lap. A 100fly short course is now just 20 strokes. That's nuts!

I knew the fastest kids in HS was like 4:22 I think first got high 4:19. So basically 1 second faster per 25 is insane.

I thought he was gonna break 4min ngl

I'm a dawn lucky french with Leon ! The show must go on :-)

Wait, what 😳

There’s no way he doesn’t go sub 4:00 for the 400IM in Paris after a swim like that.

🤯

The guys going 4:10 in the heat look so pedestrian😶

he was trying to go sub 4...

he is a fish (and nobody can convince me otherwise)

What does John Culhane think?

Can he do Thorpe’s record in LC

Yards, what are they? What century are we in again?

❤️❤️❤️🏊🏊🏊❤️❤️❤️👌👌👌❤️❤️❤️👊👊👊🏊🏊🏊 4:02 min for 500 yard (457.2 metre) Freestyle swim - WoW.

Marchand will lead off in 39.89 and send dressing back into retirement

Short course swimmimg is not about findimg the fastest swimmer, but the fastest turner.

"Fabriqué en France"! 😁🇫🇷🇫🇷

The thing is only people in America are swimming 500y in competition otherwise I'm sure other athletes would be pushing the record more, I'm more interested to see the LCM performance at the olympics.

Might be a hot take but this is only because of how much the women’s 400 free world record has just been destroyed. But I believe the men’s 400 free world record is a soft record. Think about it in 2009 peligrini broke 4 minutes for the first time the same time 3:40.07 was set. Then Ledecky brought the record from 3:59 to 3:56 then Arnie has now brought it to 3:55 while the men’s record has stagnated but today gave me hope that while not Leon will race it I believe the 400 free will hopefully and finally move on from 3:40s

Americans. Yards. Why? When will this nation adopt distances from a modern world?

Underwaters is the difference

Smoke Show

I was expecting sub 4

can we talk about how hot this guy is

leon will go sub 4 next year

I thought the record was gonna be 3:58:36 seriously Leon could do a ridiculous time like that!

Chemistry is the difference
