In Tyler Hamilton's 2012 book The Secret Race (written with Daniel Coyle), the cyclist exposes the most sophisticated doping program in the history of sports, orchestrated by Lance Armstrong, the seven-time Tour de France winner now stripped of his titles after a thorough investigation by the U.S. Anti-Doping Agency. Hamilton shows how such an elaborate system was maintained through the “omertà rule”--the code of silence that leads one to believe everyone else believes doping is the norm--and reinforced by the threat of punishment for speaking out or not complying.
