Summer McIntosh swims to record-setting gold in 400m individual medley at U.S. Open

Canada's swimming superstar Summer McIntosh, who has been dubbed a once-in-a-generation talent, has done it again.

On Friday night in Greensboro, N.C., at the U.S. Open swimming competition, McIntosh won gold in the 400-metre individual medley.

Her time of 4:28.61 is a Canadian record and the world junior record in the event. It's also the fourth-fastest performance in the history of the 400-m IM.

McIntosh finished just two seconds off the world record time of 4:26.36 set by Katinka Hosszu of Hungary in 2016.
