Olympic 800 meters gold medallist and world champion Athing Mu (20) will be coached by track great Bob Kersee, the 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 US history.
He trained wife Jackie Joyner-Kersee, a three-times Olympic gold medallist, and the United States' most decorated track and field athlete Allyson Felix until she hung up her spikes this year.
Kersee also coaches 400 metres 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.
