U.S. track star Sydney McLaughlin broke her own world record in the 400-meter hurdles Friday while competing at the World Athletics Championships in Eugene, Oregon.
The 22-year-old clocked a time of 50.68 seconds, beating her previous record time of 51.41 which was set last month. This marks the fourth time in 13 months that McLaughlin has broken the 400-meter hurdles world record.
