Caster Semenya has booked her place at the London Olympic Games as she aims to win the 800m title for the first time.
The former world champion clocked a time of 1:59.58 seconds in Pretoria to book her place at the London Games - this is the second time that she has achieved the qualifying time this season.
Semenya was plagued by a back injury at the world championships in Daegu last summer and she was unable to successfully defend her 800m crown - however she did pick up a silver medal in the event.
It was 2009 where Semenya really burst onto the international scene as she stormed to the World title in a time of 1:55.45.
But after the victory she was subjected to gender tests and did not run for eleven months while she was the investigation was ongoing.
This will be the first Olympic Games for Semenya, who ran at the Commonwealth Games for South Africa back in 2008.
