Organizers of Beijing's half-marathon stripped the winner of his gold medal, say reports. Video evidence appeared to show African runners slow to allow China's He Jie to overtake and win. Robert Keter then waves at He to overtake and signals to the other two African runners to pull back. AdvertisementThe investigation revealed the three African runners to be pacemakers, hired by Chinese sports company Xtep, which sponsored both He and the Beijing Half Marathon, but it did not inform the organizers.
