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 after an investigation into doping allegations, called the Lance Armstrong doping case, found he used performance-enhancing drugs over his career. He is currently banned for life from all sanctioned bicycling events.
