OMAHA — Katie Ledecky set herself up to swim a third individual event at the Rio Games, qualifying fastest for the 800-meter freestyle final at the United States Olympic trials on Friday.
Ledecky’s time of 8 minutes 10.91 seconds in the preliminaries was the third-fastest in the world this year. Ledecky, 19, made a name for herself by winning the 800 free four years ago in London and owns the 10 best times in the event’s history.
