Stroke by Stroke: Singapore 2025 Swimming Results Highlight Rising Performances
The World Aquatics Championships in Singapore came to a fitting, record-breaking conclusion with the Women’s 4x100m Medley Relay, the final event on the last night of racing in Singapore. The American quartet of Regan Smith, Kate Douglass, Gretchen Walsh and Torri Huske lowered their own World Record set at the Paris 2024 Olympics.
“It’s not over until it’s over, and Team USA always knows how to finish with a bang, and I think it just sends a really positive message out to the viewers at home," said Team USA's lead-off backstroker Smith. "I’m so excited for the future.”
When it comes to women’s distance swimming, what is former was still present in Singapore as Katie Ledecky of the United States—the all-time leader in individual world titles—took on her greatest distance challenge yet. It required a Championship Record and the third-fastest 800m swim of her career. Still, the four-time Olympic gold medallist held off strong challenges from Australia’s Lani Pallister and Canada’s Summer McIntosh to win her seventh consecutive world title in the event. With victories in both the 800m and 1500m freestyle in Singapore, Ledecky brought her career tally to 23 world titles—second only to Michael Phelps in total world championship golds, including relays.
The Championships fittingly came to a showstopping conclusion as Leon Marchand—who captivated the world with a World Record at Fukuoka 2023 and four Olympic golds on home soil in Paris—secured his second gold in Singapore with victory in the men’s 400m individual medley. That followed his World Record-setting swim in the 200m individual medley earlier in the week.
Two other standout performances on the final night bookended Marchand’s second individual medley gold. Tunisia’s Ahmed Jaouadi completed the 800m/1500m double with a thrilling victory over Germany’s Sven Schwarz in the shorter distance, while Canada’s Summer McIntosh claimed her fourth world title in Singapore with a Championship Record in the women’s 400m individual medley.
