Standford — Olympic champion Caster Semenya said on Sunday she would not defend her world title in Doha in September if she could not run in the 800m because of new testosterone regulations imposed by the sport’s governing body.

“If I am not running 800m, I’m not running in the World Championships,” the 28-year-old South African said after winning her favourite event in one minute, 55.70 at the Prefontaine Classic Diamond League meeting. “No 1,500m, nothing. I am just going to take a vacation and then come [back to competing] next year.”
