Regan Smith, Lilly King, Gretchen Walsh, and Torri Huske took home the final Olympic swimming event on Sunday in the women's 4x100 medley, and also set the world record in the event.
The group swam the race in 3:49.63, beating the previous record, also owned by the United States, by 0.77 seconds.
It was a wire-to-wire victory for the Americans, thanks to the insane backstroke by Smith to start - her leg alone was 0.15 seconds shy of the world record time.
