Summer McIntosh swam the fourth-fastest 400m individual medley in history and the eighth-fastest 200m butterfly ever at the first Tyr Pro Series meet since she won three golds at the Paris Olympics.
McIntosh, an 18-year-old Canadian, won Friday’s 400m IM in 4 minutes, 26.98 seconds in Westmont, Illinois.
The only faster times ever are her world record of 4:24.38, her former world record of 4:25.87 and Hungarian Katinka Hosszu’s former world record of 4:26.36.
“Overall happy with the time, but always wish it could be better and try to bring down that world record,” McIntosh said on Peacock.

On Thursday, McIntosh swam the fastest 200m butterfly ever this early in a year, winning over Regan Smith in a duel between the Olympic gold and silver medalists.
McIntosh clocked 2:04.00, distancing Smith by 2.87 seconds. She won the 200m fly at the 2024 Olympics in 2:03.03, the second-fastest time in history.
China’s Liu Zige owns the world record of 2:01.81 from 2009, the only women’s world record still standing from the super-suit era of 2008 and 2009.
McIntosh could be on track to challenge that record at this summer’s World Championships in Singapore.
In 2023, McIntosh swam 2:05.05 in early March, then went down to 2:04.06 to win that summer’s world title.
In 2024, she swam 2:05.73 in January and 2:04.33 in May before dropping to 2:03.03 at the Olympics.
Last week, McIntosh announced that she wants to swim five individual events at worlds — up from four at the Paris Olympics. After this season, she plans to move to a new, to-be-determined training base.
“I’m still so young, and I have so many new events that I want to try out and see how much I can improve on along with sticking to things that I know as well with the 200m fly,” she said Thursday. “It’s just a start, and as long as I keep improving, that’s the only goal I have for myself.”
Also in Westmont, seven-time Olympic medalist Simone Manuel won the 100m freestyle on Thursday in 53.23, her best time ever before the month of May, and then won the 200m free on Friday.
Manuel prevailed over a 100m free field that included Canadian Penny Oleksiak, the woman with whom she shared 2016 Olympic 100m free gold. Oleksiak was fifth Thursday in 54.56.
“My biggest goal (in 2025) is just having fun and taking the pressure off of myself,” Manuel said. “It’s been a really challenging last couple of years, so it’s really nice to kind of have a full four years to hopefully reach some hard goals.”
Kate Douglass, the 2024 Olympic 200m breaststroke gold medalist, defeated Lilly King, the 2016 Olympic 100m breast gold medalist, in King’s favored 100m distance.
U.S. swimmers are preparing for the national championships from June 3-7 in Indianapolis, where the team will be determined for worlds.
The Westmont Pro Series concludes Saturday with finals at 7 p.m. ET, live on the USA Swimming Network.
The next Pro Series meet is April 2-5 in Sacramento, California.
