Rio Highlights: Katie Ledecky, Michael Phelps Win Gold; Simone Biles Wows

United States’ Katie Ledecky celebrates winning the gold medal in the women’s 400-meter freestyle setting a new world record during the swimming competitions at the 2016 Summer Olympics, Sunday, Aug. 7, 2016, in Rio de Janeiro, Brazil.

U.S. swimmer Michael Phelps added to his Olympic record, winning a 19th gold medal on Sunday night, while American Katie Ledecky smashed her own world mark in the 400-meter freestyle at the Summer Games.

In his first race in Rio, Phelps swam a powerful second leg in the 4×100-meter freestyle relay. His 47.12 split gave the Americans a clear lead, which they held for a narrow win over France.

Now in his fifth Olympics, Phelps has won 23 medals overall and still has a shot at more.
