At just 18, Summer McIntosh delivered one of the most dominant and graceful performances in recent swimming memory at the 2025 World Aquatics Championships in Singapore. Her victory in the women’s 400 metre individual medley, clocking a blistering 4:25.78, was not only a meet-winning performance—it marked her fourth individual gold and fifth medal of the competition, firmly etching her name among swimming’s elite.
🏆 Dominance with Depth: McIntosh’s Medal Run
Across five individual events, McIntosh’s medal tally included:
- Gold in the 400 m medley, winning by over seven seconds and setting a championship record.
- Gold in the 400 m freestyle, her first at these Worlds, with a time of 3:56.26—nearly two seconds ahead of the field.
- Gold in the 200 m individual medley, fending off US challenger Alex Walsh to keep her bid for five golds alive. Victory came in 2:06.69.
- Gold in the 200 m butterfly, clocking a personal best and championship record of 2:01.99—just 0.18 seconds shy of the long-standing world record.
- Bronze in the 800 m freestyle, narrowly beaten by all-time great Katie Ledecky in 8:07.29—ending her pursuit of five golds.
She thus became only the third female swimmer ever to win five individual medals at a single World Championship—joining Michael Phelps (2007) and Sarah Sjöström (2019).
Beyond the Medals: A Reflection of Ambition
Even in victory, McIntosh remained focused on more. After the 400 m IM, she admitted:
“My goal was five golds. That says a lot… the things I’m learning… are going to make me hungry.”
Her reaction to the butterfly wasn’t celebration but analysis—edging the record by fractions and lamenting a slight fade in the final metres. It’s a driving mindset unprecedented at her age.
Setting Canadian History
- With four golds and a bronze, McIntosh was the sole gold medalist for Canada at the meet.
- Her individual medal count at the meet—five medals—tied the second-highest in history by a woman at Worlds.
- She now holds 11 career individual World Championship medals—the most ever by a Canadian swimmer.
- Post-meet, she was honored as Best Female Athlete of the Championships by World Aquatics, solidifying her status as the tournament’s standout.
Team Canada and Global Standings
While McIntosh lit up the pool, Canada’s overall tally was modest—four golds, all hers—earning fourth place on the medal table. The U.S. topped the standings with nine golds thanks to a stunning world-record women’s 4×100 m medley relay performance in the final event (3:49.34).
What It Means for the Future
Now focused on the 2028 Los Angeles Olympics, McIntosh brings momentum and maturity. Her ability to thrive through gruelling back-to-backs, manage pressure, and set personal bests in every race marks her as a parcel of greatness-in-waiting. She announced after the 400 IM:
“I’m going to keep pushing into next season and into L.A.”
Her resilience and resolve mirror her competitors—Léon Marchand for example, who rebounded from a slow qualifying heat to win the men’s 400 IM gold.
In Summary
Summer McIntosh’s performance at the 2025 World Championships will resonate for years as one of swimming’s most commanding displays by a teenager. With four golds and five individual medals, she joined the ranks of Phelps and Sjöström in history books, while continuing to chase bigger records and bolder goals.
At 18, she already owns the most individual World Championship medals of any Canadian and has her eyes set on bigger targets—five golds, world records, and Olympic glory. If Singapore was a statement, McIntosh’s future might just redefine the sport.
