The South African athlete claimed gold over 800m at the Olympics
South African middle distance runner Caster Semenya proved her dominance on the track once again this week, with her first international 400m win.
The 25-year-old, who was previously subjected to sex tests over disputes about her gender, added another gold medal at the Diamond League in Brussels, to the one she clinched at the Rio Olympics recently.
But this time, instead of lining up in the 800m event, she switched to the shorter distance of 400m, where the 25-year-old thrived once again. But it wasn't until the final 100m that she put herself in contention for a medal and a final push over the remaining metres ensured that the medal would be hers.
She set a personal best of 50.40 seconds on route to her win in a field which included five Rio 2016 finalists and bronze medallist Shericka Jackson.
Semenya was first subjected to gender verification tests in 2009 when doubts were first raised about whether or not she should be competing against women. She was issued a temporary ban but was cleared to resume competing 11 months later.
