Sixteen-year-old Summer McIntosh of Toronto has set a world record in the women's 400-metre freestyle event at the Canadian swimming trials.
McIntosh finished the 400-metre event in three minutes, 56.08 seconds, breaking the record of 3:56.40 that was set last year by Australia's Ariarne Titmus.
McIntosh previously held the Canadian record in the event at 3:59.32.
McIntosh, who earned silver in the 400 freestyle at last year's world championships, won two gold and a bronze at the same world meet.
McIntosh first attracted national attention when she competed at the Tokyo Olympics in 2021 as a 14-year-old, ending up fourth in the 400-metre freestyle event.
The Canadian swimming trials, which opened Tuesday, are being held to select athletes for the world championships and Pan American Games later this year.
