Watch: Nashville's Gretchen Walsh clinches spot for Paris Olympics with US swim trial win

Gretchen Walsh owns a world record.

Now the former Harpeth Hall swimming star is an Olympian.

Walsh, a Nashville native and senior at Virginia, won the 100-meter butterfly Sunday at the U.S. Olympic Swimming Trials in Indianapolis to secure a spot on the team for the 2024 Paris Games.

Walsh won with a time of 55.31 seconds, the second-fastest in history. The fastest? Her own world record, set Saturday in the semifinals in 55.18.

"I'm still in shock," Walsh said during an NBC interview. "I don't even know what to say. Making the team was the biggest goal, but getting a world record was absolute insanity."

Walsh was the youngest of 1,500 swimmers at the 2016 Olympic Trials but did not qualify. 

She was the first swimmer to break 48 seconds in the 100-yard butterfly at the NCAA championships. The time discrepancy between the Olympic and NCAA events is due to the length and measurement of the pools (50 meters vs. 25 yards, respectively).
