Mcintosh, a three-time Olympic gold medal-list and former world record-holder in the event, sliced more than a second off the previous world record of 3:55.38 set by Australian Ariarne Titmus at the 2023 World Championships in Fukuoka, Japan.

"Going into tonight I knew that my training has been really good these past few months, and I knew that I could do something special," the 18-year-old star said. "I mean, I didn't think my training would be 54.1, but I'm really happy with that overall."

It was Mcintosh's first race of the trials in Victoria, British Columbia, selection meet for the worlds in Singapore July 11-August 3.

She's entered in seven events, including the 800m free, 400m individual medley, 200m individual medley, 200m free, 200m butterfly and 200m backstroke.

She has indicated she aims to compete in five events at worlds.
