Canadian teen Summer McIntosh shatters 400 metres freestyle record
The 18-year-old Paris Olympics triple gold medallist breaks mark set by Australia’s Ariarne Titmus at 2023 World Championships in Fukuoka

Canadian three-time Olympic champion Summer McIntosh set a world record in the women’s 400 metres freestyle at the Canadian Swimming Trials in Victoria, British Columbia, on Saturday.
The 18-year-old clocked three minutes and 54.18 seconds to better Australian Ariarne Titmus’ mark of 3:55.38 set 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,” McIntosh told public broadcaster CBC.
“So being able to input my training in doing that – I didn’t think my training would be 54.1, but I’m really happy with that.”
At the Paris Olympics, McIntosh became the first athlete from Canada to win three gold medals at a single Games.
