Kate Douglass Shatters 50m Freestyle World Record as Lani Pallister Hands Katie Ledecky Historic Defeat

Australian swimmer Lani Pallister dealt US great Katie Ledecky her first 800 metres freestyle defeat in a major international meet, beating her one-time idol at the 2026 Pan Pacific Championships in Irvine, California, on Saturday. Pallister led wire-to-wire en route to victory in 8 minutes, 6.1 seconds, and Ledecky’s desperate late charge was not enough as she finished second in 8:07.26.

It was a stunning result on the final day of Pan Pacs action that saw American Kate Douglass break the 50m freestyle world record twice on the way to gold and earn 200m breaststroke silver and medley relay gold as well. Ledecky has dominated the 800m since she won Olympic gold in 2012 as a 15-year-old, winning 13 international golds since then, including four Olympic gold medals and seven world titles in the event.

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.”

Douglass 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. 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, and capped her night swimming the freestyle anchor leg for the US 4×100 medley relay team to take gold in 3:50.43.

In other events, Chinese Olympian Yu Yiting upset world record-holder Summer McIntosh in the 200m individual medley to win in 2:07.45. Meanwhile, Australia's Sam Short clocked an Australian record of 14:33.97 to add the 1,500m freestyle gold to his 400m and 800m titles.
