Ledecky is the favorite to win 200 and 800 freestyle and anchor the favored U.S. women in the 4x200 freestyle relay. Sarah Sjostrom of Sweden crushed the field in the 100 meter butterfly with a world record time of 55.48. In the 100-meter breaststroke, Adam Peaty of Great Britain broke his world record for the second time in two days, winning in 57.13. Peaty, who led wire-to wire, set the world record of 57.55 in his qualifying heat Saturday. Sjostrom had set an Olympic record in the event Sunday in the qualifying heat, then did herself one better by breaking her own world record in the final.
