“I am a woman and I am fast”: what Caster Semenya’s story says about gender and race in sports

The constant scrutiny into the runner’s medical history reveals what happens to women who don’t conform to stereotypes.
“I am Mokgadi Caster Semenya. I am a woman and I am fast.”
So said the reigning Olympic champion in the women’s 800-meter last year, in a statement challenging rules that could threaten her athletic career.
The rules, issued by the International Association of Athletics Federations (IAAF), require some female runners whose bodies produce high levels of testosterone to take medication to lower those levels. Many saw the rules as a direct effort to target Semenya, who is believed to have a condition that produces high testosterone. The runner appealed the new regulations, but on Wednesday, the Court of Arbitration for Sport ruled against her.
