Before these Olympics are over, Katie Ledecky will become a house hold name and one of the most decorated American athletes at these games. She is not only willing events, she is destroying the competition. Ledecky took home the gold for Team USA with a stunning time of 3:56.46, two seconds ahead of her own record pace.

At this point, all that’s left for Katie Ledecky to chase is history.

So she does.

The 19-year-old swimming superstar entered these Olympics as the current world-record holder in the 400, 800 and 1,500 meter freestyles. The challenge when she swims those events here? To beat her past, slower self.

On Sunday night, she did just that, knocking nearly two seconds off the world record in the 400 free to secure her first gold medal of these Games. She won in 3:56.46, followed by Britain’s Jazz Carlin and American Leah Smith, who were almost five seconds behind.
