Maurer’s time was more than a full second faster than what he went to win this event in 2025 as a sophomore, touching in 3:34.00, which previously made him the 5th fastest performer in history.
This swim moves him up two spots to #3 all-time in the event, only trailing NCAA record-holder Leon Marchand‘s 3:28.82, and Cal’s Hugo Gonzalez de Oliveira‘s 2022 NCAA championships swim of 3:32.88.
All-Time Top 400 IM Performers:
Leon Marchand – 3:28.82 (2023) Hugo González de Oliveira – 3:32.88 (2022) Rex Maurer – 3:32.96 (2026) Chase Kalisz – 3:33.42 (2017) Carson Foster – 3:33.79 (2022)Maurer was in control of this race from start to finish, opening in 48.22 on the butterfly, giving him more than half a second of cushion between himself and the rest of the field. That momentum was carried through to the backstroke as Maurer then opened up to a near two-second cushion at the halfway mark, turning in 1:41.28.
Though his weakest stroke, Maurer held strong on the breaststroke, as he would split 1:01.76, a near second faster than his 2025 breaststroke split of 1:02.72. By the 300, Maurer still held a decent lead, but nobody would catch the Longhorns mid-distance ace as he would storm home in 49.72 to put the finishing touches on a record-breaking swim.
