MONACO (AP) — The governing body of track and field will not apply rules to limit natural testosterone levels in female runners until the Court of Arbitration for Sport concludes a case involving Olympic champion Caster Semenya.
The IAAF says the Nov. 1 start has been delayed until CAS gives a verdict "expected on or before" March 26.
That target is six months and two days before the 2019 world championships start in Doha, Qatar. Semenya is the current 800-meter world champion.
If the IAAF's rules for athletes with differences of sex development (DSD) are upheld by the court, female runners must medicate to reduce their testosterone levels for six months before racing internationally from 400 meters through the mile.
The IAAF expects a February appeal hearing for Semenya.
