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.

Happy for Rex. Happy for his mom, Coach Lea, as well.

I’m thinking this may be Dan Schemmel‘s last year. At the US Trials for the 2023 World Championships, none of his swimmers made the finals. At US Olympic trials in June 2024, none of his active roster swimmers made the finals. Quite a come down from the glory years.

easy to saw after the fact but I bet Rex would’ve been in Paris if he had started last year with Bob.

What about Hobson, he is probably the most talented of the group but only went 412

Hobson was 4:15-4:16 at midseason the last two years and ended up 4:07.3 and 4:06.9. He’s a big taper guy. If he’s 4:12 already he’ll be just fine in March.
