Seven Deadly Sins: My Pursuit of Lance Armstrong

Seven Deadly Sins: My Pursuit of Lance Armstrong is a 2012 book written by the Sunday Times journalist David Walsh. In the book, Walsh writes about his 13-year fight to bring out the truth behind American cyclist Lance Armstrong's seven Tour de France wins, i.e. that Armstrong had used banned substances. Walsh was vindicated when Armstrong was stripped of all seven of his Tour titles, and banned from cycling for life, on October 22, 2012. Armstrong's seven Tour wins have been described as his "Seven Deadly Sins."

The book was released on December 13, 2012.
