Katie Ledecky crushes the first women’s 1,500-meter freestyle at the Olympics.

Katie Ledecky won her first gold medal of the Tokyo Games on Wednesday, dominating the 1,500-meter freestyle, just as she was expected to.

For Ledecky, the 1,500 victory in 15 minutes 37.34 seconds capped off a busy morning at the Tokyo Aquatics Center. It came a little more than an hour after she suffered the biggest disappointment of her Olympic career as she failed to get on the podium in the 200-meter freestyle race.

Erica Sullivan of the United States finished second in 15:41.41, more than four seconds behind Ledecky but good enough for silver. Sarah Kohler of Germany won bronze in 15:42.91.

This was the first time women have been able to race at 1,500 meters at the Olympic Games, even though men have been competing at the distance for decades.
