Summer McIntosh Wins 4th Gold at World Championships, Nears Phelps Record

Canadian swimming phenom Summer McIntosh closed out the 2025 World Aquatics Championships in dominant fashion, securing her fourth gold medal of the competition in the women’s 400m individual medley. The 18-year-old from Toronto not only won the race — she set a new championship record with a time of 4:25.78, finishing well ahead of her closest competitors from Australia and Japan.

This marks McIntosh’s fourth gold of the meet, following victories in the 200m butterfly, 400m freestyle, and 200m individual medley. She also earned a bronze in the 800m freestyle behind American star Katie Ledecky. McIntosh’s total haul of five medals this week brings her career World Championship count to 13, including an impressive eight golds.

With this performance, McIntosh is now just one gold medal shy of tying Michael Phelps’ all-time record for the most golds at a single world championship. Her incredible consistency and dominance across multiple events have solidified her status as one of the brightest talents in international swimming. As Canada’s top medal winner of the meet, she continues to raise the bar for Canadian sport on the global stage.
