FINA World champion Summer McIntosh broke her Canadian and World Junior Record in the women’s 400m Individual Medley with a dominant race at the U.S. Open swimming competition.

McIntosh, 16, clocked 4:28.61 eclipsing her previous best of 4:29.01 set at the 2022 Commonwealth Games, which took place this past summer in Birmingham.  Prior to the Commonwealth Games, McIntosh won gold in the event at the 19th FINA World Championships Budapest 2022.

‘’I’m really happy overall with my race,’’ said McIntosh, whose time was the fourth fastest in history in the event.  ‘’It’s still pretty early on in the season so I didn’t really know what to expect from it. It’s my first time racing long course this season and I’m really happy with that.’’

USA's Emma Weyant was second in 4:41.85, with Kathryn Hazle third at 4:47.56. 

Katinka Hosszu of Hungary holds the world mark at 4:26.36 set in 2016. Ye Shiwen of China swam 4:28.43 in 2012 and Hosszu did 4:28.58, also in 2016.

‘’There’s always so much to learn with every race good or bad,’’ said McIntosh, a silver medallist in the 400-m freestyle on Thursday. ‘’I’m just going to continue to keep improving and working on all the little details.’’
