Olympic Champion Sydney McLaughlin broke her own world record in the 400-meter hurdles at the US outdoor track and field championships.
She crossed the finish line at Hayward Field in 51.41 seconds, breaking her own record of 51.46 set last year at the Tokyo Games, where she won the gold medal.
She previously set the record with a 51.90-seconds performance at the U.S. Olympic trials a year ago, only to shatter that figure in Tokyo, collecting gold in 51.46.
