Defiant Semenya threatens to skip world championships

STANFORD, California - Olympic champion Caster Semenya said on Sunday she would not defend her world title in Doha in September if she cannot run in the 800 meters because of new testosterone regulations imposed by the sport's governing body.

"If I am not running the 800m, I'm not running in the world championships," the South African said after winning her favorite event in one minute, 55.70 seconds at the Prefontaine Classic Diamond League meeting in California.

"No 1,500 (meters), nothing. I am just going to take a vacation, and then come (back to competing) next year."
