Olympic Medalist Katharine Berkoff Smashes American Record and Signs Multiyear Deal with Global Swimwear Brand, A3 Performance!

INDIANAPOLIS and NEW YORK, June 26, 2025 /PRNewswire/ -- Olympic medalist, Katharine Berkoff, continues to make waves in the swimming world—this time by setting a new American Record and U.S. Open Record in the Women's 50m Backstroke with a blistering 26.97 seconds at the 2025 U.S. National Championships in Indianapolis.

This historic swim comes less than a year after Berkoff earned a gold medal in the 4×100 Medley Relay and bronze in the 100m Backstroke at the 2024 Paris Olympics—making her the first NC State women's swimmer to medal at the Olympic Games. Berkoff now ranks #2 all-time globally in the 50m Backstroke, just 0.11 seconds shy of the world record, solidifying her reputation as one of the fastest female backstrokers in history.

In tandem with her record-breaking performance, A3 Performance—a global leader in high-performance swimwear—has officially announced a multiyear endorsement deal with Berkoff. The partnership marks A3's first-ever exclusive contract with a U.S. Olympic swimmer, signaling a new era for the brand.

"Katharine is an exceptional athlete and person. When we met for the first time, I knew this was the right relationship for us. Then she went out and broke the American Record. We're excited to see what the future holds for Katharine and A3 as we continue to work together." said Dan Meinholz, Founder and CEO of A3 Performance. "Her relentless pursuit of excellence and dynamic presence both in and out of competition align perfectly with our brand's vision for innovation and inspiration. We're honored to support her next chapter."

Berkoff echoed the excitement, stating:

            "The A3 Performance suit is incredible. I truly feel the difference, and when you are swimming against the best athletes in the world, you have to believe you are in the best suit. A3 Performance is for me."
