The world of athletics must be breathing a sigh of relief following the Caster Semenya ruling to restrict the level of testosterone in female runners, but I expect the South African athlete will continue to win big races.
Her record over the past 10 years has been outstanding. Testosterone apart, she may possess that magical quality absent in many competitors – the overpowering will to dominate a race and succeed. The controversial decision by the Court of Arbitration for Sport to uphold rules that suppress testosterone in competitors may prove extremely difficult to put into practice.
