What do you do if your left leg is 1 inch shorter than your right leg and has only a fraction of the power of your right leg? According to Bj rn Rasmussen you train harder. Bj rn got polio (infantile paralysis) in 1941, when he was only a week old. The polio attack was so violent that the doctors asked for permission to let him die. "But my parents wanted me to live" says Bj rn. "Therefore I can write this book." This is a book about a boy who could barely walk up the stairs when he was in school, but later in life completed an Ironman - a triathlon - consisting of 3.8 km swimming, 180 km cycling and a marathon of 42 km.
