Summer McIntosh's Historic Swim: Second Fastest 400m Freestyle Ever! (2026)

Summer McIntosh, the Canadian swimming sensation, made a splash at the 2025 U.S. Open Swimming Championships, leaving spectators in awe. With a time of 3:55.37 in the 400m freestyle, she claimed the second-fastest spot in history, just behind her own world record of 3:54.18. This performance was a testament to her resilience, as she returned to the pool after a withdrawal from the short-course World Cup in October due to an injury concern.

The JoeJamail Texas Swimming Center witnessed a stellar display of swimming prowess on December 4th. McIntosh dominated the finals, finishing over 15 seconds ahead of runner-up Anna Peplowski, who clocked 4:10.55. Her performance was a clear statement of intent, especially in her first race under the guidance of renowned coach Bob Bowman.

McIntosh expressed her satisfaction, stating, 'I'm pretty happy with that overall. It was my first race back for the season, and my first race under Bob [Bowman], so I was pretty pumped up for it.' She added, 'That’s definitely, by far, the fastest I’ve gone in-season, so I’m excited [to see] what I can do in the next coming months.'

The Bowman training group had even more to celebrate. Leon Marchand, a four-time Olympic champion, showcased his prowess in the men’s 400m freestyle, finishing in 3:44.70, ahead of the North American teenager Luka Mijatovic. This performance marked a return to form for Marchand, who had shown signs of vulnerability in his preferred events during the short-course World Cup.

The Team USA's Kate Douglass made headlines by winning the women’s 50m freestyle (24.20) and 200m individual medley (2:07.85). Shaine Casas (24.53) narrowly edged out Australian teenager Henry Elmore Allan (24.65) in the men’s 50m backstroke. Hungary’s Hubert Kos dominated the men’s 200m individual medley, and Katharine Berkoff thrilled the home crowd with a victory in the women’s 50m backstroke.

The U.S. Open Championships continue on Friday, December 5th, with more thrilling races including the 100m butterfly, 100m backstroke, 100m breaststroke, 200m freestyle, and 400m individual medley. The event promises to be a showcase of talent and determination, leaving fans eagerly anticipating the next big swim showdown.
