Gretchen Walsh, a senior at Virginia, sets world record at Olympic trials

Gretchen Walsh outdid herself and the rest of the world at the U.S. Olympic swimming trials Saturday when she shattered the women’s 100-meter butterfly world record in her semifinal race at Lucas Oil Stadium in Indianapolis.

She posted a 55.18 time in the two-lap event, breaking Swedish swimmer Sarah Sjöström’s 55.48 mark from 2016. 

“I didn’t think I was going to do it tonight,” said Walsh, who on Sunday went on to make the U.S. Olympic team. “I just knew that I wanted to go a best time, and now, here I am, world record holder. It’s actually insane. 

Gretchen Walsh reacts after setting a world record during the 100 butterfly semifinals June 15, 2024, during the U.S. Olympic Team Swimming Trials at Lucas Oil Stadium in Indianapolis.

“I think I was probably the most shocked of all the people I know. I think that they all had confidence in me. … I was absolutely in awe. Totally surprised.”

The 21-year-old University of Virginia star opened the day with an impressive 55.94 race in prelims to easily qualify for the semifinals, when she stormed out with another blistering performance. 

While Walsh dominated the second semifinal of the day, Regan Smith finished second at 55.92 to advance to Sunday’s final. Torri Huske won the first semifinal, posting a 55.79 time nearly breaking her own American record, and advanced as well. 

“It’s definitely been an emotional night,” Walsh said. “Luckily I have had experiences like this — obviously not breaking a world record but just trying to keep my emotions controlled. 

“I have a time where I’m going to put my phone down tonight and just let it be and hopefully get a good night’s rest. But I warmed down, and I iced, and [stuck] to my recovery routine. So I’m hoping tomorrow night I just get a spot on the team because that’s really what I came here to do.”
