A transgender swimmer on the University of Pennsylvania womens team continued to smash records in the pool over the weekend.

Lia Thomas won the 200-yard freestyle in 1:41.93 at the Zippy Invitational in Akron, Ohio, on Saturday to break the schools all-time mark and establish the best time in the nation this season, according to the university. On Sunday, she won the 1,650 freestyle by more than 38 seconds in 15:59.71 to set another university record.

In a previous meet against Ivy League rivals Princeton and Cornell, Thomas won the 500 free in what was the best collegiate time (a Princeton record 4:35.06) so far, in addition to capturing the 100 and 200.
