Sprinting great Usain Bolt refuses to dwell on the disappointment of being stripped of his Beijing Olympics 4x100 meters gold medal after Jamaican team mate Nesta Carter tested positive for a banned stimulant. Bolt completed the treble treble of 100m, 200m and 4x100m Olympic titles at the 2016 Rio Games, but has had his 2008 relay gold stripped after Carters re-tested sample indicated he had taken methylhexaneamine.
