Lance Edward Armstrong (born Lance Edward Gunderson on September 18, 1971) is an American former professional road racing cyclist. Armstrong is the 1993 professional world champion, and won the Tour de France a record seven consecutive times from 1999 to 2005. However, in 2012, he was banned from sanctioned Olympic sports for life as a result of long-term doping offenses. As part of those sanctions, all results going back to August 1998, including his seven Tour wins, were voided.
At age 16, Armstrong began competing as a triathlete and was a national sprint-course triathlon champion in 1989 and 1990. In 1992, Armstrong began his career as a professional cyclist with the Motorola team. He had notable success between 1993 and 1996, including stage 8 of the Tour de France and the World Championship in 1993, the Clásica de San Sebastián in 1995, Tour DuPont in 1995 and 1996, and a handful of stage victories in Europe, including stage 18 of the 1995 Tour de France.
