Lance Armstrong, considered by many to be the greatest professional cyclist, admits in an interview with Oprah Winfrey that he did cheat by doping despite years of vehemently denying the charges. The U.S. Anti-Doping Agency in October 2012 brought forth a case against Armstrong, a cancer survivor who started the charitable foundation Livestrong, that led to the stripping of his cycling titles and a lifetime ban that was upheld by the International Cycling Union.
