South African middle distance athlete, Caster Semenya, is aiming to run in the 200 metres at the 2020 Tokyo Olympics.
By doing so, she will be competing over a distance that will allow her to avoid World Athletics’ regulations limiting her testosterone levels.
Semenya is a double Olympic gold medallist in the 800 metres but, as an athlete with differences in sexual development (DSD), is bound by regulations.
The regulations limit normal levels of testosterone in competitors racing in events ranging from 400m to a mile.
“My dream has always been, and will continue to be, to compete at the highest level of sports,” Semenya, 29, said in a statement.
“And so, in order to pursue my goals and dreams, I have decided to change events and compete in the 200 metres.
“This decision has not been an easy one. But, as always, I look forward to the challenge and will work hard, doing all I can to qualify for Tokyo and compete to the best of my ability for South Africa.”
Semenya had been seen training with sprint start blocks in recent weeks, leading to speculation she would look to reinvent herself over a shorter distance.
But she must still earn her place in Tokyo and is some way off the Olympic qualifying time of 22.80.
She has a personal best of 24.26 seconds in the 200m set in Feb. 2019.
