U.S. teenager Katie Ledecky sliced almost six seconds off her own world mark in the women's 1,500-meter freestyle on Sunday, winning in 15 minutes, 28.36 seconds to post her second world record in as many nights at the Pan Pacific championships.
The 17-year-old Ledecky improved her record in the 400 freestyle on Saturday. She collected her fifth gold medal of the meet in convincing fashion in cool but clear conditions on the last night of competition.
It was the third time in 13 months she's set the mark in the 1,500, and the second in three months since her 15:34.23 at Shenandoah on June 19.
