Two-time Olympic champion Caster Semenya will race the 3,000 meters at the Diamond League Prefontaine Classic on June 30, a distance she can contest without reducing her testosterone levels.
The South African has won two Olympic golds at 800 meters, and has insisted she will not take medication to comply with new International Association of Athletics Federations (IAAF) rules governing testosterone levels in women athletes that went into effect on May 8.
