Swim of the Week is brought to you by arena, a SwimSwam partner.
Disclaimer: Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The Swim of the Week is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.
Ryan Erisman hit the ground running for the 2026 long course season, though that should’ve come as no surprise after his breakout summer of 2025 was followed by a standout freshman year at Cal.
The 19-year-old was on fire at last week’s AP Race London International, shattering his personal best times in the men’s 400, 800 and 1500 free and climbing the all-time U.S. rankings.
In the 400 free, Erisman went head-to-head with Germany’s Oliver Klemet, nearly pulling off the upset victory in a time of 3:44.03, with Klemet claiming the win in 3:44.01.
The swim for Erisman knocked nearly two seconds off his personal time of 3:46.01, set at last summer’s U.S. National Championships, which also previously stood as the boys’ 17-18 National Age Group Record.

In the 800, he clocked a blazing-fast 7:45.42, doing so with a big negative split (3:54.57/3:50.85), to drop more than six seconds off his best time of 7:51.74 and climb to #7 all-time among Americans.
He also broke 15 minutes for the first time in the 1500, clocking 14:59.30 to rank 18th all-time among Americans. His previous best time, set in January, sat at 15:06.94.
These swims came after he had a trio of top-three finishes at his debut ACC Championships in February, and followed up with three top-10 finishes at the NCAA Championships in March.
Prior to that, he also had a strong showing in January at the Pro Swim Series stop in Austin, setting best times in the 100, 200 and 1500 free, and the 200 fly.
Although Erisman won’t be representing this summer at the Pan Pacific Championships, his performances in London establish him as a frontrunner to be a big part of the 2027 World Championship and 2028 Olympic teams.
