BERLIN -- South Africa's track and field federation has been asked to conduct a gender test on an 800-meter runner amid concerns she does not meet the requirements to compete as a woman.
Caster Semenya, 18, won the 800 meters at the world championships with a stunningly dominating run.
Semenya took the lead halfway through the race Wednesday and won in a world-leading 1 minute, 55.45 seconds, beating defending champion Janeth Jepkosgei of Kenya by a massive 2.45 seconds. Jennifer Meadows of Britain took bronze.
The world track and field federation requested the gender test about three weeks ago, after Semenya burst onto the scene by improving her personal bests in the 800 and 1,500 by huge margins.
