A man has been dominating women’s Ivy League swimming this year, including the championships held this weekend at Harvard.

Controversial transgender swimmer Lia Thomas won the “women’s” 500 freestyle with a time of 4:37.32. It was the fastest time ever recorded at Harvard’s Blodgett Pool for a women’s sporting event. The woman with the best time in the event was Catherine Buroker, also from the University of Pennsylvania. She finished seven seconds behind Thomas, who, until recently, competed in men’s swimming at Penn.
