ADELAIDE, Australia (AP) — Olympic gold medalist Ariarne Titmus has broken the women’s 400-meter freestyle world record at the Australian swimming championships. Titmus finished in 3 minutes, 56.40 seconds in the final at the South Australian Aquatic Centre to improve on Katie Ledecky’s previous mark of 3:56.46 that the American set at the 2016 Rio Olympics.
Titmus beat Ledecky for Olympic gold in the 400 and 200 and finished behind the American star in the 800-meter freestyle final at the Tokyo Games last year.
