Lance Edward Armstrong (born Lance Edward Gunderson on September 18, 1971) is an American professional road racing cyclist who rides for UCI ProTeam Astana.

He won the Tour de France a record-breaking seven consecutive years, from 1999 to 2005. He is the only person to win seven times, having broken the previous record of five wins, shared by Miguel Indurain, Bernard Hinault, Eddy Merckx and Jacques Anquetil. He has survived testicular cancer, a tumor that metastasized to his brain and lungs in 1996.
His cancer treatments included brain and testicular surgery and extensive chemotherapy, and his prognosis was originally poor.

In 1999, he was named the American Broadcasting Company (ABC) Wide World of Sports Athlete of the Year. In 2000 he won the Prince of Asturias Award in Sports. In 2002, Sports Illustrated magazine named him Sportsman of the Year. He was also named Associated Press Male Athlete of the Year for the years 2002–2005. He received ESPN's ESPY Award for Best Male Athlete in 2003, 2004, 2005, and 2006, and won the BBC Sports Personality of the Year Overseas Personality Award in 2003. Armstrong retired from racing on July 24, 2005, at the end of the 2005 Tour de France, but returned to competitive cycling in January 2009, finishing third in the 2009 Tour de France.

Career

Early career

Armstrong was born on September 18, 1971, in Plano, Texas, a northern suburb of Dallas. He began as a triathlete, winning adult competitions from the age of 13. In the 1987–1988 Tri-Fed/Texas ("Tri-Fed" was the former name of USA Triathlon), Armstrong was the number one ranked triathlete in the 19-and-under group; second place was Chann McRae, who became a US Postal Service cycling teammate and the 2002 USPRO national champion. Armstrong's points total for 1987 as an amateur was better than the five professionals ranked that year. At 16, Armstrong became a professional triathlete and became national sprint-course triathlon champion in 1989 and 1990 at 18 and 19, respectively.

It became clear that his greatest talent was as a bicycle racer after he won the U.S. amateur championship in 1991. Representing the U.S., he finished 14th in the 1992 Summer Olympics with the help of teammates Bob Mionske and Timm Peddie. Also in 1992, Armstrong competed in the Tour of Ireland race.
