Kenyan Faith Kipyegon set a world record in the 1,500 meters on Saturday at the Prefontaine Classic, finishing in 3 minutes, 48.68 seconds.
Kipyegon, a three-time Olympic champion in the event, bested her own record of 3:49.04, set last July before the Paris Games.
Kipyegon, 31, sprinted alone down the stretch cheered by the sellout crowd at Hayward Field. After crossing the finish line, she wrapped herself in the Kenyan flag.
Ethiopian Diribe Welteji was second in 3:51.44, Australian Jessica Hull, who was the silver medalist behind Kipyegon at the Olympics last year, was third in 3:52.67.
"To be honest, the ladies are pushing me too because they are running quick now and I'm happy that when I broke a world record, they are all running very fast, and that is what I wanted, to motivate the younger generation to come and do even better. For them to follow me, it feels so great that they are pushing me as well to break records," Kipyegon said.
