McIntosh Swims 2:01.65 to Set Women's 200-Meter Butterfly World Record

Summer McIntosh set a new world record in the women's 200-meter butterfly on July 5 at the Canadian trials in Montreal. She finished the race in 2 minutes 1.65 seconds, 0.16 seconds faster than the previous mark of 2:01.81 set by China's Liu Zige at the National Games in October 2009. McIntosh had come within 0.18 seconds of the record in 2025 with a time of 2:01.99 at the world championships.

The 19-year-old Canadian slammed her fists into the water and smiled as the crowd erupted inside the Olympic pool. "As you can see my emotions, this is the absolute world [to me]," McIntosh said after the race. "Growing up this is the one world record I thought I would never break and to do it tonight is really special in front of a home crowd.

McIntosh won three gold medals at the 2024 Paris Olympics. She trains in Austin, Texas, under coach Bob Bowman and already holds world records in the 200-meter individual medley, 400-meter individual medley and 400-meter freestyle. She has won eight world championships since 2022.

McIntosh is scheduled to compete in the 400-meter individual medley on July 6, the 400-meter freestyle on July 7 and the 200-meter individual medley on July 8 at the trials for the Pan Pacific Championships in Irvine, California.
