American swimmer Katie Ledecky triumphed in the 800m freestyle final at the World Aquatics Championships held in Singapore, recording a championship-best time of 8:05.62. This victory marks her seventh consecutive world title in the event, further solidifying her status as one of the sport's greatest competitors. Ledecky narrowly defeated Australia's Lani Pallister, who clocked 8:05.98, and Summer McIntosh of Canada, who took bronze at 8:07.29. Ledecky noted, “That’s pretty incredible, three of us going under 8:10 ... incredibly fast. They pushed me all the way,” after the race, reflecting the competitive spirit of the event.

This race ended McIntosh’s pursuit of making Michael Phelps's record of five individual gold medals at a single world championship. The 18-year-old Canadian had already secured gold titles in the 400m freestyle and 200m individual medley at the championships, offering a bright future for the athlete despite her setback in the 800m freestyle final. McIntosh expressed her disappointment, stating, “The feeling right now is something I never want to feel again,” while remaining optimistic for her upcoming 400m medley race.

On the same day, the United States team also set a world record in the mixed 4x100m freestyle relay, finishing in 3:18.48, breaking their own previous record. This success marked a rebound for the US team, which had faced criticism earlier in the championships. Gretchen Walsh added to the excitement for the American team by winning gold in the 50m butterfly event, clocking 24.83 seconds. Walsh stated, “I’m very proud,” following her victories, highlighting the resilience shown by the team amidst challenges.

In addition to Ledecky's and Walsh's credentials, the championships saw dominant performances from Chinese divers. China continued to assert its strength, claiming both gold and silver in the women’s 3m springboard event. Chen Yiwen secured gold with 389.70 points, further contributing to China's overall success at the competition.
