Author of "Tour de Lance" on Lance Armstrong

The U.S. Anti-Doping Agency today slapped Lance Armstrong with a life-time ban and said the superstar cyclist will be stripped of his seven Tour de France titles, after Armstrong announced he's giving up his battle to clear his name of doping charges.

Armstrong maintains he's innocent, that he's never used performance enhancing drugs, and that he's never once tested positive.

So why then is he giving up the fight to clear his name and save his legacy?

Bill Strickland, editor-at-large at “Bicycling” magazine, has followed Armstrong's career from the beginning. He shares his take with Anderson.
