Gold Medal Olympic Runner for South Africa
Keynote | MC | Presenter
Caster Semenya is a South African middle-distance runner and 2016 Olympic gold medallist. She won gold in the women’s 800 metres at the 2009 World Championships with a time of 1:55.45, the 2016 Summer Olympics, and the 2017 World Championships in her new personal best, 1:55.16. After the doping disqualification of MariyaSavinova, she also was awarded gold medals at the 2011 World Championships and the 2012 Summer Olympics, all in the 800 metres.
Semenya is an intersex cisgender woman, assigned female at birth, with XY chromosomes and naturally elevated testosterone levels due to 5α-Reductase deficiency. Following her victory at the 2009 World Championships, it was announced that she had been subjected to sex testing. She was withdrawn from international competition until 6 July 2010 when the International Association of Athletics Federations (IAAF) cleared her to return. In 2019, new IAAF rules came into force preventing women such as Semenya from participating in 400m, 800m, and 1500m events unless they take medication to lower their testosterone levels.
Semenya was named one of Time magazine’s 100 Most Influential People of 2019.
