Canadian swimming sensation Summer McIntosh delivered another historic performance on Sunday, breaking the longest-standing individual women’s swimming world record in the 200-meter butterfly during the Canadian Swimming Trials.

The 19-year-old touched the wall in an astonishing 2:01.65, eclipsing the previous world record of 2:01.81 set by China’s Liu Zige at the 2009 World Championships during the so-called “super-suit era,” when polyurethane swimsuits contributed to a wave of record-breaking performances before they were banned.

A Historic Milestone

McIntosh shaved 0.16 seconds off a record that had stood for nearly 16 years, making it the oldest individual women’s world record in swimming. The achievement further cements her status as one of the sport’s brightest stars ahead of the next World Championships.

After seeing her time appear on the scoreboard, McIntosh celebrated by slamming her fists into the water before breaking into a wide smile as the crowd inside the Canadian Olympic pool erupted in applause.

Back Home After New Training Move

The Canadian Swimming Trials marked the first opportunity for many home fans to watch McIntosh race since her high-profile move to Austin, Texas, where she now trains under renowned coach Bob Bowman.

Bowman is best known for coaching Michael Phelps throughout his legendary career, helping the American become the most decorated Olympian in history with 23 Olympic gold medals.

Another Chapter in a Remarkable Career

McIntosh has rapidly established herself as one of swimming’s dominant athletes. The Canadian won three Olympic gold medals at the Paris 2024 Olympic Games and continues to rewrite the record books across multiple disciplines.

Her latest performance not only erased one of swimming’s oldest records but also demonstrated her ability to challenge marks that many believed would stand for years to come. With the World Championships approaching, McIntosh will enter the competition as one of the favorites across several events.
