Every sports fan loves a great comeback. Is there a special quality shared by top athletes who triumph over great challenges? And can anyone acquire it? In The Comeback Quotient, celebrated sports writer Matt Fitzgerald supplies the answer to both questions. He identifies these mega-achievers of astounding athletic comebacks as 'ultrarealists,' men and women who succeed where others fail by fully accepting, embracing, and addressing the reality of their situations. From ultrarunners like Rob Krar to triathletes like Mirinda Carfrae to rowers, skiers, cyclists, and runners all over the world, Fitzgerald highlights and speculates on just what makes these comebacks so compelling. As for whether anyone can stage his or her own great comeback, the answer is a resounding yes: Anyone can become an ultrarealist to some degree. In the tradition of his bestselling How Bad Do You Want It?, The Comeback Quotient combines gripping sports stories with mind-blowing science to deliver a book that will forever change how you perceive the challenges you face, giving you the inspiration and the tools to make the next great comeback you witness your own.
