The 25-year-old has faced objection to her involvement because she has a condition meaning her testosterone levels are far higher than normal. But Semenya has taken to Instagram to goad her detractors, saying: 'Dear Haters, I have so much more for you to be mad at. Just be patient.'
Officials at Rio 2016 are concerned that hostility towards 25-year-old Caster Semenya could spill over into violence. The athlete has been assigned a security detail amid fears that she could be targeted by fans of her rivals.
Viewers compared her running to that of Jamaican sprinter Usain Bolt, saying she was 'making it look like a warm up' and 'just strolled to the finish line'.
Another said: 'I love how Caster Semenya jogs like a boss whilst other contestants sprint on Full Mode.'
