Runner Caster Semenya says she's not done fighting for the right to compete

She has two Olympic golds and four podium finishes at the World Championships. But Caster Semenya can no longer compete in elite competition, all because of what's long defined the middle distance runner more than her athletic achievement: her gender. Semenya has higher testosterone levels than average women, which has made her a lightning rod in conversations around gender in sports for years. Now, she's telling her own story in a memoir called The Race to Be Myself. She joins Piya Chattopadhyay to talk about being the subject of debate in public and how she's keeping up her fight for all women to be respected and included in sports.
