RIO DE JANEIRO (AP) — Caster Semenya cruised through her 800-meter heat at the Olympics on Wednesday and then was as quick through the media section at the stadium, declining to talk to reporters in apparent anticipation of a barrage of questions on track and field's contentious testosterone rules.
Semenya, the 25-year-old South African runner caught up in a sex-test drama at the 2009 world championships, has been under intense scrutiny ever since.
With her focus only on competition and after a dominating run this season, Semenya is tipped to have a chance of breaking the 800-meter world record in Rio.
