A stunning performance by Canadian swimmer Summer mcintosh at the 2025 U.S. open Championships has silenced any doubts about her form,as she clocked the second-fastest 400m freestyle time in history – 3:55.37 – on Thursday,December 4th,at the Joe Jamail Texas Swimming Center.

McIntosh returns with a Statement

The swim,while not surpassing her own world record of 3:54.18,was a resounding success following her withdrawal from the short-course World Cup in October. Observers at the event were captivated by McIntosh’s performance, with one attendee remarking it was difficult to believe what they were witnessing. She finished a remarkable 15 seconds ahead of the runner-up,Anna Peplowski,who finished with a time of 4:10.55.

“I’m pretty happy with that ” McIntosh shared with broadcasters. “This 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.”

Did you know? – Summer McIntosh is only 17 years old, yet she’s already one of the most dominant forces in international swimming, holding world records and consistently breaking personal bests.

Bowman Training Group Shines

The success wasn’t limited to McIntosh. The Bob Bowman training group enjoyed a particularly strong showing, with four-time Olympic champion Leon Marchand also securing a victory in the men’s 400m freestyle. Marchand finished with a time of 3:44.70, narrowly defeating Luka Mijatovic (3:45.30). This win marked a return to peak form for the French superstar, who had previously displayed some vulnerability during the short-course World cup.

Douglass and Casas Lead Team USA

Team USA also delivered impressive results. Kate Douglass claimed wins in both the women’s 50m freestyle (24.20) and 200m individual medley (2:07.85). In a closely contested race, Shaine casas secured victory in the men’s 50m backstroke with a time of 24.53, edging out Australian teenager Henry Elmore Allan (24.65).

Pro tip: – Swimmers often use in-season meets like the U.S.open to test race strategies and build endurance, rather than aiming for peak performance. This allows for adjustments before major championships.

International Competition Heats Up

Beyond the dominant performances from McIntosh, Marchand, Douglass, and Casas, other international athletes also made their mark. Hungary’s Hubert Kos demonstrated his prowess in the men’s 200m individual medley, capitalizing on Marchand’s absence. Meanwhile, Katharine Berkoff thrilled the home crowd with a win in the women’s 50m backstroke.
