Olympian Katie Ledecky set a national high school swimming record on Friday.

Fifteen-year-old Olympic gold medalist Katie Ledecky continues to make a big splash in swimming, this time on the national high school level.

On Friday the sophomore sensation, now performing for Stone Ridge School of the Sacred Heart (Bethesda, Md.), won the 500-yard freestyle in a national-record time of 4:33.14 during the Metro Championships in Boyds, Md. The previous record was 4:33.35 set by Katie Ziegler in 2006.

According to Swimming World Magazine, the 800-meter gold medal champion, who lowered her career best (4:34.53), now holds the sixth-fastest time in USA history for the event. Katie Hoff holds the overall record of 4:30.47.

In addition, Ledecky also holds 15-16 age-group records in the 1000 and 1650 freestyle. She also still owns 13-14 age-group records for 500 and 1000 yards.
