IRVINE, Calif. (AP) - Katie Ledecky broke the world record in the 400-meter freestyle at the U.S. national championships, becoming the first woman since Janet Evans to own world marks in the 400, 800 and 1,500 freestyles at the same time.
The 17-year-old from Bethesda, Maryland, won in 3 minutes, 58.86 seconds Saturday night. She was under world-record pace the entire race.
Ledecky swam the third-fastest time ever in the morning preliminaries, clocking 3:59.82. She joined Italy's Federica Pellegrini as the only women to break 4 minutes in the event, with Ledecky dipping under that barrier three times now. She is the current world champion.
Evans owned all three women's freestyle world records from 1988 to 2006.
