Lani Pallister has toppled swimming legend Katie Ledecky for a second time in 24 hours to complete her stunning Pan Pacific championship campaign with her fourth gold medal.
The 24-year-old Pallister was under world record pace for much of the race as she won the 800m freestyle final in eight minutes 6.10 seconds from four-time Olympic champion Ledecky (8:07.26) in the American's signature event.
Ledecky's lone previous defeat in an 800 free final since 2010 came in a small domestic meet in February 2024 against Canadian superstar Summer McIntosh.
