FILE - In this July 18, 2005 file photo, overall leader of the Tour de France cycling race, Lance Armstrong, right, relaxes with compatriot and teammate George Hincapie outside their hotel in Pau, southwestern France. Hincapie was the "Loyal Lieutenant" who helped Armstrong to seven Tour de France titles, only to later provide the key testimony that brought his downfall. Now, Hincapie is peeling back the shroud that has long covered the dark era of doping in cycling in a book due out next month that is part memoir, part mea culpa. (AP Photo/Alessandro Trovati, File)
