Lance Edward Armstrong (born Lance Edward Gunderson; September 18, 1971) is an American former professional road racing cyclist. Armstrong had won the Tour de France a record seven consecutive times between 1999 and 2005, before being disqualified from those races and banned from cycling for life for doping offenses by the United States Anti-Doping Agency (USADA) in 2012. He is the founder of the Livestrong Foundation, originally called the Lance Armstrong Foundation, which provides support for cancer patients.
At 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 the 1993 World Championship, Clásica de San Sebastián in 1995, an overall victory in the penultimate Tour DuPont and a handful of stage victories in Europe, including the stage to Limoges in the Tour de France.
In October 1996, he was diagnosed with testicular cancer that had spread to his brain and lungs. His cancer treatments included brain and testicular surgery and extensive chemotherapy. In February 1997, he was declared cancer-free and the same year he founded the Lance Armstrong Foundation. By January 1998, Armstrong had renewed serious cycling training, having signed a new racing contract with US Postal. He was a member of the US Postal/Discovery team between 1998 and 2005. On July 24, 2005, Armstrong retired from racing at the end of the 2005 Tour de France, but returned to competitive cycling with the Astana team in January 2009 and finished third in the 2009 Tour de France. Between 2010 and 2011, he raced with the UCI ProTeam he helped found, Team Radio Shack.
