Olympic champion Sydney McLaughlin has broken her own world record in the 400 metres hurdles at the US track and field championships.
McLaughlin clocked 51.41 seconds to win the final in Eugene, Oregon on Saturday, bettering the world mark of 51.46 set last year at the Tokyo Games, where she won the gold medal.
She said she had no idea what to expect as she cleared the last hurdle.
“I was just gonna finish the race. You know anything is possible,” she said. “I’m just really grateful for it.”
Britton Wilson finished 1.67 seconds behind with Shamier Little taking third in 53.92.
The top three finishers in each event at the national championships will represent the United States in the world outdoor championships, also at Eugene’s Hayward Field, next month.
Allyson Felix, the most decorated woman in track history, finished sixth in the 400m, in what was her final national championship race.
Felix, who announced in April that this will be her final season, is enjoying the final days of her illustrious career – which includes 11 Olympic medals. She plans to run her final official race in her native Los Angeles in August.
Despite her finish, Felix will is expected make the mixed relay team at worlds.
NCAA champion Talitha Diggs of Florida won the 400 in 50.22 seconds. Dalilah Muhammad sat out of the race because of a slight injury, but she has already qualified for the world championships as the defending champion in the event.
Asked if she was disappointed with the finish, Felix laughed.
“Honestly no. You guys know the 400 is hard for me. It’s not my natural passion, it’s always just been something I challenged myself with,” she said.
