The series of events surrounding Floyd Landis's 2006 Tour de France was as improbable as anything in the history of sports: He showed up nine seconds late for the race's opening prologue, donned the leader's yellow jersey twelve days later, and lost his lead only to regain it in remarkable fashion just before the Tour's final stage into Paris. Winning the Tour should have been the culmination of a life's dream, but a mere three days later, Landis was accused of using banned performance-enhancing drugs. Released by his team and threatened with the removal of his Tour title, Landis went from winning the most prestigious race of his career to being unfairly labeled as a cheater, a liar, and a doper."Positively False" is at once a memoir and a powerful indictment of the unchecked governing bodies of cycling that have compromised theintegrity of the sport as a whole.
