LOS ANGELES (AP) — Tyler Hamilton’s tell-all book about Lance Armstrong and doping in cycling will be released two weeks earlier than originally planned.

“The Secret Race: Inside the Hidden World of the Tour de France: Doping, Cover-ups, and Winning at All Costs,” is now scheduled for release Sept. 5.

Ballantine Bantam Dell touts the book as the “first deeply detailed window into one of the defining sports stories of our time.”

Armstrong said last week he would not pursue arbitration in a case brought by the U.S. Anti-Doping Agency, which stripped his record seven Tour de France titles.

Included in the case was Hamilton’s interview with “60 Minutes” claiming he had personal knowledge of Armstrong doping.

Armstrong has steadfastly denied doping but said he was tired of fighting USADA.
