For the first time in Olympic history, an American woman has won the 400-meter hurdles.
Dalilah Muhammad got off to a blazing start -- despite running in rain -- and did not let up in an absolutely fabulous run Thursday night. Muhammad pushed herself immediately, roared past the field and maintained her lead down the final 200 meters. Muhammad got to the finish line in 53.13, a definitive win over Denmark's Sara Petersen, who won silver with a 53.55 run.
American Ashley Spencer had a tremendous final 100 meters to earn bronze, crossing in 53.72 and continuing a great program for the United States in hurdles at these Olympics.
With this win, the United States has now, at some point in its history, taken gold in every track event that requires starting blocks.
