Former cyclist Lance Armstrong confesses to his doping in an airing of Oprah's Next Chapter.

Lance Edward Armstrong is an American former professional road racing cyclist. He achieved international fame for winning the Tour de France a record seven consecutive times from 1999 to 2005, but was stripped of his titles in 2012 after an investigation into doping allegations found that Armstrong used performance-enhancing drugs over his career. Armstrong is banned from all sanctioned bicycling events.

United States Anti-Doping Agency v. Lance Armstrong, the Lance Armstrong doping case, was a major doping investigation that led to retired American road racing cyclist Lance Armstrong being stripped of his seven consecutive Tour de France titles, along with one Olympic medal, and his eventual admission to using performance-enhancing drugs. The United States Anti-Doping Agency (USADA) portrayed Armstrong as the ringleader of what it called "the most sophisticated, professionalized and successful doping program that sport has ever seen."
