Lance Edward Armstrong (né Gunderson; born September 18, 1971) 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.
At age 16, Armstrong began competing as a triathlete and was a national sprint-course triathlon champion in 1989 and 1990. In 1992, he began his career as a professional cyclist with the Motorola team.
