The curtains might have come down on the career of Olympic 800m bronze medalists Margaret Nyairera Wambui after her name was struck out of the Stockholm Diamond League Meeting on May 30 in Sweden.
Nyairera, 24, has declined to take medication that will lower her strength. She is one of several star female athletes affected by an International Association of Athletics Federations (IAAF) ruling this month that requires women with high levels of testosterone to take medication to suppress it.
