MONTREAL – Summer McIntosh smashed the women’s 400m freestyle world record in winning the title at the Canadian Swimming Trials in 3min 54.18sec on June 7, sending a signal for the upcoming world championships in Singapore.

McIntosh, a three-time Olympic gold medallist 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. I mean, I didn’t think my training would be 54.1, but I’m really happy with that overall,” the 18-year-old star said.

It was McIntosh’s first race of the trials in Victoria, British Columbia, selection meet for the July 11-Aug 3 worlds in Singapore.

While she is entered in seven events, including the 800m free, 400m individual medley, 200m individual medley, 200m free, 200m butterfly and 200m backstroke, McIntosh has indicated she aims to compete in five events at worlds.
