19-year old Arizona State freshman Leon Marchand won the 400 IM on Friday evening at the NC State Fall Invitational in Greensboro, North Carolina. his time of 3:35.62 is the 5th-best time in NCAA or USA Swimming history, and the second-fastest time ever by a freshman.

What’s more, he did so in his second ever 400 IM race in yards, with his first coming in prelims on Friday morning.

Fastest 400 IMs in NCAA History: Performances

  1. Chase Kalisz, Sr., Georgia, 2017 – 3:33.42
  2. Chase Kasliz, So., Georgia, 2014 – 3:34.50
  3. Carson Foster, Fr., Texas, 2020 – 3:35.27
  4. Abrahm Devine, Jr., Stanford, 2018 – 3:35.29
  5. Leon Marchand, Fr., Arizona State, 2021 – 3:35.62

By performers, Marchand now ranks 4th both in NCAA history and all-time.

His time is also faster than the 3:36.90 that Florida’s Bobby Finke swam to win the NCAA Championship last season. Foster’s time was the fastest of the season, but came in October and not at the NCAA Championships.

Splits Comparisons

Kalisz Foster Finke Marchand
US Open Record Freshman Record NCAA Title Time Wolfpack Invite
Fly 49.78 49.04 50.53 49.24
Back 53.9 53.93 55.44 55.35
Breast 58.61 60.92 61.49 60.61
Free 51.13 51.38 49.44 50.42
Final Time 3:33.42 3:35.27 3:36.90 3:35.62

The splits comparison shows how balanced Marchand is in his 400 IM. If he had to choose a stroke specialty, it would be breaststroke or butterfly, but he’s really a ‘true’ IM’er in the sense that he’s just very good at all 4 strokes and very good at putting them together into a complete race.

The Frenchman finished 6th in the 400 IM in the Tokyo 2020 Olympic Games in 4:11.16, short of his 4:09 French Record, and was 18th in the 200 IM and 14th in the 200 fly.

Marchand is in his first few months of training and competing in yards and under Arizona State head coach Bob Bowman – most famous for his work as the head coach of the 400 IM World Record holder Michael Phelps.

Marchand isn’t the only new addition to Arizona State’s IM group this season either: former Arizona Wildcat David Schlicht joined the team this season. He finished 2nd on Thursday in 3:40.60. He was 4th in the 400 IM in a 3:39.89 last season. Arizona State’s Jarod Arroyo, who was a Tokyo 2020 Puerto Rican Olympian, finished 4th in 3:45.89. That’s just .08 seconds slower than his lifetime best from March.

Congratulations to Leon! It should also be mentioned that this was the first time he had done 400 IM short course yards in competition.. By the way he did a 140.80 200 SCY IM yesterday on the second time he did that distance in competition!

Agree! My error! As you pointed out it is still an extraordinary accomplishment for a swimmer whose previous experience has been long course meters!

If anyone’s going to do it though, Finke is probably the guy.
