Athing Mu, an Olympic 800-meter gold medalist and world champion, will be coached by track great Bob Kersee, the 20-year-old American said on social media on Wednesday.
Mu, the youngest woman to win both an Olympic and a world individual title in track, will relocate from Texas to Los Angeles to train with Kersee, one of the most successful coaches in U.S. history.
He trained wife, Jackie Joyner-Kersee, a three-time Olympic gold medalist, as well as Allyson Felix, until she hung up her spikes this year.
"Coach Kersee has the capability to further enhance by running skills and implement the tools needed to reach my greatest potential," Mu said on Twitter.
Kersee also coaches 400-meter hurdles world record holder Sydney McLaughlin, with whom Mu collected relay gold in Tokyo last year. Mu will have a bye into her key event at the 2023 World Championships in Budapest.
