Michael Phelps Kisses Gold For 19th Time, Katie Ledecky Breaks Her Own Record

Michael Phelps won gold as the United States won the 4x100 relay at the Olympics on Sunday. The Americans' traditional rival in the event, France, finished second as Australia finished third. The gold was Phelp's 23rd medal: 19 gold, 2 silvers and 2 bronzes. Retiring after the 2012 Olympics, Phelps decided to return in part because of the disappointment with how the American men swam in the 4x100 relay at the 2013 world championships as they lost to France. Phelps said his 47.12 split was the fastest relay split he'd ever swam in his career, and that he's happy to close out his final Olympics the way he wants, with gold. 

While competing in the 400-meter freestyle, Katie Ledecky was racing nothing but the clock. It was simply no contest. The teenager gave the United States its first swimming gold medal of the Rio Olympics on Sunday night, as she crushed her own world record in the 400-meter freestyle. With Ledecky dominating the longer freestyle events since winning gold in the 800 free at the London Olympics as a 15-year-old, the results were totally expected. With a time of 3:56:46, she crushed the mark of 3:58:37 that she nearly set two years ago on the Gold Coast of Australia and has been chasing every since.
