Lance Armstrong 1 of 9

Lance Armstrong is famous not only for winning cycling's prestigious Tour de France seven consecutive times, but also for battling and surviving testicular cancer. However, based on blood samples obtained in 2009 and 2010 and testimonies from other athletes, Armstrong was accused of drug doping and trafficking. A lengthy investigation by the U.S. Anti-Doping Agency (USADA) into his use of performance-enhancing drugs led to him being stripped of all his racing results since August 1998 and banned from professional cycling for life. Armstrong continues to deny any wrongdoing.
