Caster Semenya retained her 5,000 metres title at the South African Athletics Championships on Thursday and confirmed she would not be attempting to qualify for the 200m at the Tokyo Games.
The double Olympic 800-metres champion cannot compete over her favoured distance having refused to abide by a World Athletics ruling that athletes with differences in sexual development (DSDs) competing in races ranging from 400 metres to a mile must reduce their naturally high levels of testosterone.
