Texas transfer Rex Maurer swam to an American Record in the men’s 500 freestyle, posting a 4:04.45 in his win on Wednesday night. Maurer broke the previous record of a 4:06.32 set by Florida’s Kieran Smith at 2020 SECs and 2021 NCAAs.

Note: Carson Foster went a 4:05.81 earlier tonight but we are searching for splits. That race was also considered an “unofficial” record.

Split Comparison:

Maurer Smith (2020)
50 22.24 22.45
100 24.82 24.83
150 25.12 24.79
200 25.04 25.01
250 24.86 25.17
300 24.96 25.1
350 24.8 25.05
400 24.75 24.85
450 24.41 24.94
500 23.45 24.13
4:04.45 4:06.32

Maurer also moves up to become the #2 performer all-time, sitting only behind Leon Marchand who swam a 4:02.31 to win the event at 2024 NCAAs. Maurer notably swam the 500 free at NCAAs this past March, finishing 31st in a 4:16.69. Maurer spent last season as a first-year with Stanford and has since transferred to Texas.

In addition to a new American Record, Maurer also swam to a Texas record. The previous school record stood at a 4:06.93 that Luke Hobson posted at 2024 NCAAs. Hobson was 4th tonight in a 4:12.92.

How does Maurer beat Foster so handily all of a sudden?

I may have missed this piece, but does Leon Marchand not have the American record because he is of French citizenship?

Yes. You have to be American to hold an American Record. Leon is not an American.

I’m guessing the US Open record is open to all athletes regardless of citizenship.
The American record is only for American citizens.
Got it

all the hype for Bowman but I imagine he does most of his training with Erik Posegay. Congrats to all 3

the downvotes seem harsh lol, posegay is the distance coach and it”s a 500 record haha. i said congrats to all 3, bet bot hbowman and posegay have helped him/have him in their groups occasionally.

I knew Amherst should have taken the chance to get him in the transfer portal – what a mistake. This guy is the real deal.

The splitting of the race is testament to great training and discipline. It is exciting to have the genius of Coach Bowman again revealed by this effort. Obviously Rex put in the work and trusts the training. It takes a village including family, teammates and staff – So happy for the Maurer clan!
