Leon Marchand Rips 3:34.45 400 IM, Pac-12 Record and #2 Performance All-Time


Men’s 400 IM:

  • A Standard: 3:39.16
  • B Standard: 3:51.46
  • Pac-12 Record: 3:35.29, Abrahm DeVine, Stanford, 2018
  • Pac-12 Championship Record: 3:36.60 Hugo Gonzalez, Cal, 2020
  • 2021 NCAA Invite Time: 3:45.67

Top 3:

  1. Leon Marchand (ASU) – 3:34.45
  2. Hugo Gonzalez (Cal) – 3:36.54
  3. Jason Louser (Cal) – 3:38.77

Arizona State freshman Leon Marchand is continuing to have a meet for the ages. After becoming the fastest freshman ever in the 200 IM last night, Marchand doubled down, winning the 400 IM as well, and posting the 2nd-fastest performance all-time in the process. That’s right – not only did Marchand shatter the Pac-12 meet and conference records with his swim, he’s now the 2nd-fastest 400 IM’er in NCAA history, and he’s just a freshman.

Marchand’s 3:34.45 comes in just over a second off Chase Kalisz‘s NCAA Record of 3:33.42, which he swam at the 2017 NCAAs. Of course, Marchand was excellent on all 4 strokes tonight, but he particularly great on the front half of the race. He split 49.53 on fly and 54.31 on backstroke, both of which led the field in tonight’s A final. Taking a broader view, here is a split comparison between Marchand tonight and Chase Kalisz‘s NCAA Record of 3:33.42.

Stroke Leon Marchand – 2022 Pac-12 Finals (Pac-12 Record) Chase Kalisz – 2017 NCAA Championships (NCAA Record)
Fly 49.53 49.78
Back 54.31 53.90
Breast 1:00.74 58.61
Free 49.87 51.13
Final Time 3:34.45 3:33.42

As you can see in the comparison, despite how great Marchand was on backstroke tonight, Kalisz was even better on his record swim, and he was way faster on breaststroke. Marchand has superior freestyle speed to Kalisz, but if he’s going to challenge Kalisz’s record, it’s probably going to have to come through improving the middle 200 of the race.

Here are the current all-time top 5 performers in the 400 IM:

Rank Time Swimmer Meet
1 3:33.42 Chase Kalisz 2017 NCAAs
2 3:34.45 Leon Marchand 2022 Pac-12 Championships
3 3:35.27 Carson Foster 2020 ST TEX First Chance Invite
4 3:35.29 Abrahm DeVine 2018 NCAAs
5 3:35.76 Hugo Gonzalez 2018 SEC Championships

Not to be overlooked, Cal’s Hugo Gonzalez took 2nd in 3:36.54, marking his 2nd-fastest performance ever. The swim ties for 16th-fastest performance all-time in the event. Gonzalez’s personal best comes in at 3:35.76, which he swam at the 2018 SEC Championships. Gonzalez’s personal best makes him the #5 performer all-time in the event.

Remember Marchand is still only a freshman 19 years old and still developing.

why does pac12 make it impossible to watch?

3.34 was expected.
I must admit that what has impressed me the most so far this week with Léon’s performances is his monster freestyle.
He closes his IM like a bullet in the freestyle part.
1.31 low anchor leg in the 4X200 free relay.
And in my opinion the most impressive is the 41.17 anchor leg in the medley relay, especially in the same session as his 400 IM. Where does that speed come from? 😯 That’s crazy!
Like MP he swims the IM and the 200 fly. And like MP he will play a major role for his country in freestyle relays at the international level.
He has everything in store to be the greatest French male swimmer ever.

In addition he has a very polite laidback personality according to his coaches.

If I wasn’t mistaken, he was recruited by Stanford before decided on ASU. He almost came to Stanford. Imagined if he was at Stanford as a Frosh…Minakov, Polansky, Marchand…super Frosh team!

I believe he wanted to gi to cal but the scolarship was too low. In france most of the university are free and you can’t have a loan to pay a school like standford or berkley

He def wants to win the 400 IM in Paris in 2024. So the coaching combination of Bowman with tips from MP who now lives near ASU was and is an attraction. ASU is also very strong academically, and this is especially true for the swimming team.

Lemme see
