WATCH: Regan Smith Smashes McKeown’s 100 Back World Record (Day 4 Race Videos)


The Indianapolis faithful were treated to their second world record in four nights at the 2024 U.S. Olympic Trials, as Regan Smith put on a stunning display in the final of the women’s 100 backstroke.

After lowering her American Record down to 57.47 in the semis, Smith scorched a time of 57.13 in tonight’s final, knocking two-tenths off Kaylee McKeown‘s mark of 57.33 set last year.

Katharine Berkoff was the runner-up in 57.91, her second straight swim sub-58 after clocking 57.83 in the semis, to secure her spot in Paris (though not yet official).

Regan’s underwater push after the turn was just Perfectly timed & she emerged just a few inches before the 15 meter limit mark . Absolutely well executed 👌
Her kick on those last 20 meters was just enormous & stronger than anybody else
