Katie Ledecky added a third race to her Olympic schedule, cruising to a nearly 10-second victory in the 800-meter freestyle at the U.S. swimming trials Saturday night.
One night after competing in the 100 free, the 19-year-old Ledecky didn't have quite enough in the tank to challenge her own world record. She finished in 8 minutes, 10.32 seconds, far off the mark of 8:06.68 she set in January at a meet in Austin, Texas.
Still, it was another dominating performance by a swimmer who surprisingly captured gold in the 800 free four years ago, but will go into Rio as one of the biggest favorites in any sport.
