Ledecky moves into the 200m freestyle semifinals in first place after racing to one minute, 55.01 seconds; that swim comes about 14 hours after she set the 400m freestyle world record en route to picking up her first individual gold of the Rio Olympics. This afternoon, Ledecky plans on getting her rest.

“I’m gonna take a really long nap, like two hours at least,” Ledecky told Michele Tafoya in a poolside interview.
