Caster Semenya's gold medal in tonight's 800m should have been the proudest moment of the South African teenager's life. But for the athlete whose gender has been scrutinised the world over in the last 24 hours, it came as no surprise that she was advised to shun the media after her title-winning race.
As the cameras settled on the athlete who has lived her whole life as a female, onlookers pored over their TV screens, studying the woman now rumoured to be a man. Controversy has dogged the 18- year-old since she posted a world leading personal best time of 1 minute 56.72 seconds – an eight second improvement on her time last year – to win gold at the African Junior Championships in Mauritius last month. That's just 0.51 seconds slower than Kelly Holmes' career best.
