When the U.S. Anti-Doping Agency first accused the seven-time Tour de France champion of using performance-enhancing drugs, Lance vehemently denied the allegations. But after his titles were stripped from him and he was banned from cycling for life, the athlete finally changed his tune. In an interview with Oprah Winfrey, Lance revealed the truth after more than a decade of lies. "Yes or no: Did you ever take banned substances to enhance your cycling performance?" Oprah asked. "Yes," replied the shamed cyclist.
