In 1996, young cycling phenom Armstrong discovered he had testicular cancer. In 1999, he won the Tour de France. Now he's a grateful husband, a new fatherAand a memoirist: with pluck, humility and verve, this volume covers his early life, his rise through the endurance sport world and his medical difficulties. Cancer "was like being run off the road by a truck, and I've got the scars to prove it," Armstrong declares. Earlier scars, he explains, came from a stepfather he casts as unworthy; early rewards, from his hardworking mother and from the triathlons and national bike races Armstrong won as a Texas teen. "The real racing action was over in Europe": after covering that, Armstrong and Jenkins (Men Will Be Boys, with Pat Summit, etc.) ascend to the scarier challenges of diagnoses and surgeries. As he gets worse, then better, Armstrong describes the affections of his racing friends and of the professionals who cared for him. Armstrong is honest and delightful on his relationship to wife Kristin (Kik), and goes into surprising detail about the technology that let them have a child. The memoir concludes with Armstrong's French victory and the birth of their son. The book features a disarming and spotless prose style, one far above par for sports memoirs. Bicycle-racing fans will enjoy the troves of inside information and the accounts of competitions, but Armstrong has set his sights on a wider meaning and readership: "When I was sick I saw more beauty and triumph and truth in a single day than I ever did in a bike race."
