I have decided to change events and compete in the 200m – Semenya

South African middle-distance athlete Caster Semenya [COURTESY]

South African middle-distance athlete Caster Semenya is aiming to run in the 200 metres at the 2020 Tokyo Olympics, competing over a distance that would 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 limiting normal levels of testosterone in competitors racing in events ranging from 400m to a mile.
