Tour de France (Lance Armstrong Era)

Lance Armstrong’s seven Tour de France victories (1999–2005) represent the most systematic doping conspiracy in sports history. After years of denials, the U.S. Anti-Doping Agency’s 2012 report detailed a scheme involving EPO, blood transfusions, and testosterone that Armstrong called ‘the most sophisticated, professionalized and successful doping program that sport has ever seen.’ His foundation raised $500 million for cancer research, but a backdated 1999 positive test for corticosteroids shattered his legacy. The scandal forced the Tour to overhaul anti-doping rules, increasing out-of-competition tests by 60% from 2013.
