At the Toyota U.S. Open Championships on Thursday evening, Canada’s Summer McIntosh established a new record in the women’s 400-meter freestyle event.
The three-time Olympic gold medalist completed the race in three minutes and 55.37 seconds, securing first place.
She finished more than 15 seconds ahead of her closest rival, American swimmer Anna Peplowski, who came in second with a time of 4:10.55. Emma Weyant, also from the U.S., took third place with a time of 4:11.25.
The previous U.S. Open record of 3:56.81 was held by American Katie Ledecky, set last April in Fort Lauderdale, Florida.
McIntosh, hailing from Toronto, was slightly more than a second away from her world record of 3:54.18, achieved last June in Victoria.
The competition will carry on until Saturday.
