Early Friday, charges were filed against Lance Armstrong by the U.S. Anti-Doping Agency alleging that he used performance enhancing drugs. The seven-time Tour de France winner could lose some or all of his titles and face a lifetime ban from the race if these charges are found to be true. Blood-test results and teammate testimonies will be used to prove that the charges are true, says the USADA. His attorney calls the allegations “wrong” and “baseless”, while Armstrong has 10 days to contest the charges.
