Summer McIntosh Sets New 400m IM World Record at Canadian Trials

In a remarkable display of athletic prowess, 18-year-old Canadian swimmer Summer McIntosh shattered her own world record in the 400-metre individual medley (IM) at the Canadian Swimming Trials held on June 11, 2025, in Victoria, British Columbia. McIntosh clocked an impressive time of 4:23.65, marking her third world record achieved during the five-day meet, which has garnered significant attention within the swimming community.

This latest achievement for McIntosh follows her record-setting performances in the 400-metre freestyle on June 8 and the 200-metre individual medley on June 10, showcasing her exceptional talent and determination in the pool. Her consecutive victories not only highlight her dominance in these events but also position her as a leading contender for the upcoming world championships scheduled for July 26 to August 3 in Singapore, where she aims to represent Canada on the global stage.

"Going into tonight, I knew it would take an extra little push if I wanted to lower [the world record]. So, happy to go best time," McIntosh remarked in a post-race interview with CBC's Devin Heroux. She expressed satisfaction with her performance while acknowledging the potential for further improvement, stating, "I think there's still lots of room for improvement... Overall, I'm happy with the time, but I know I can go faster. But I'm excited to keep pushing this event and have room for more."

McIntosh's accomplishments extend beyond her recent records. She has also set the third-fastest time in history for the 800-metre freestyle, trailing only behind American swimming legend Katie Ledecky. Additionally, McIntosh holds multiple world records in both long-course and short-course events, including the 400-metre freestyle, 200-metre butterfly, and the 400-metre individual medley, asserting her position as one of the most promising swimmers of her generation.

Her impressive performance at the Paris Games, where she secured three gold medals and one silver, further solidifies her reputation. Looking ahead, McIntosh has set her sights on achieving five individual medals at the 2028 Los Angeles Olympics, a goal that reflects her ambition and competitive spirit.

The Canadian Swimming Trials serve as a critical qualifier for the national team ahead of the world championships, and McIntosh’s recent successes indicate a bright future for both her and the Canadian swimming program. As she continues to break records and push the boundaries of her potential, the swimming world eagerly anticipates her next feats in the pool, potentially heralding a new era of Canadian swimming excellence.
