Five-time Olympic champion Elaine Thompson-Herah will train under the same coach as Jamaica team-mate Shelly-Ann Fraser-Pryce as she prepares to defend her sprint titles at Paris 2024.
According to her management team, Thompson-Herah split from Shanikie Osbourne this month over the coach's "extremely excessive" terms. The 31-year-old, winner of 100m, 200m and 4x100m gold at Tokyo 2020, will continue her Olympic preparations with Reynaldo Walcott - coach of 10-time world champion Fraser-Pryce since 2020.
Thompson-Herah is the second-fastest woman in history over 100m and her golden treble in Tokyo came after she won 100m and 200m gold at Rio 2016. But while she has dominated women's sprinting at the past two Olympic Games, she failed to qualify for this year's World Championships in Budapest following an injury-hampered season.
Five-time world 100m champion Fraser-Pryce won the Olympic 100m title at Beijing 2008 and London 2012. She was part of her nation's successful 4x100m relay team in Tokyo - but had to settle for 100m silver behind Thompson-Herah.
"Out of difficulties grow miracles," Thompson-Herah posted on X. The athletes' management team said: "Thompson-Herah remains as dedicated as ever to her craft, demonstrating an unequivocal focus on the path ahead.
"Her commitment to excellence is unwavering and she is resolute in her pursuit of defending the double Olympic titles she so triumphantly earned."
