Australian Lani Pallister has maintained a dominant presence, securing gold medals in the women’s 200-metre, 400-metre, and 800-metre freestyle, as well as the 4x200m freestyle relay. Her victory in the 800m freestyle was particularly notable as it marked American Katie Ledecky’s first defeat in that event at a major international meet since 2012. Pallister clocked a time of 8:06.10 to defeat Ledecky, who finished in 8:07.26, ending a historic streak that included 13 international gold medals and four Olympic titles. Canada has also seen significant success, earning a total of 13 medals. Gold medalists for Team Canada include Blake Tierney in the men’s 100-metre backstroke, Alexanne Lepage in the women’s 200-metre breaststroke, and Summer McIntosh in the women’s 400-metre individual medley. McIntosh set a new championship record in the 400m individual medley with a time of 4:28.01, breaking the 2014 record of 4:31.99. Canada’s medal tally also includes four silver and six bronze medals. Other key results include China’s Yu Yiting winning the women’s 200m individual medley with a championship record of 2:07.45. In the men’s 1500m freestyle, Australia’s Sam Short broke the national record with a time of 14:33.97. The United States achieved sweeps in the 4x100m freestyle relays, with the women’s team setting both a championship and American record of 3:29.32. Following her performance, Lani Pallister was named Female Swimmer of the Meet. In addition to her previous golds, she achieved lifetime bests in the 200m, 400m, and 1500m freestyle events. Following the competition, Australian swimmers including Pallister and Sienna Toohey toured SoFi Stadium in Los Angeles, the $7 billion venue slated to serve as the swimming arena for the 2028 Olympic Games. ## Claims - Lani Pallister won the 400-meter freestyle at the Pan Pacific Championships.
