Caster Semenya Qualifies for 800 at London Games Former world champion Caster Semenya has qualified for the 800 meters at the London Olympics. The South African ran 1 minute, 59.58 seconds in a provincial meet on her home track at the University of Pretoria on Friday. It is the second time she ran faster than the qualifying time of 1:59.90, making her eligible for her first Olympics. Semenya first ran under that time when winning silver at last year's world championships in South Korea. She failed to break 2 minutes in her first two races this year but found her form in a dominant win Friday with help from Namibian pacemaker Herunga Tjipekapora. Semenya burst onto the scene at the 2009 worlds as a teenager before a gender test controversy sidelined her for 11 months.
