Katie Ledecky, who has broken 13 world records, set her first NCAA record on Saturday, lapping everybody in her race and winning by 34.85 seconds.
Ledecky, a five-time Olympic champion and Stanford freshman, took 10 seconds off the NCAA mark in the 1,000-yard freestyle in a duel meet with Texas on Saturday. She had lapped the other four swimmers with a little less than 200 yards to go.
Ledecky clocked 9:10.49 in Palo Alto, crushing Rio teammate Leah Smith‘s mark from the 2016 ACC Championships by 10 seconds. To Smith’s credit, her time came in the first 1,000 yards of a 1,650-yard free.
