Book excerpt: The bestselling author of 80/20 Running and How Bad Do You Want It? reveals his inspiring and surprising journey to see just how fast he can go. Matt Fitzgerald has been running (and writing about running) for most of his adult life. But, like many passionate amateur runners, he never felt he was quite fulfilling his potential. If he follows the training, nutrition, and lifestyle of an elite runner, just how fast could he go? In his mid-forties, Matt at last has the freedom to do nothing but train, if only for the span of one summer. The time is now. He convinces the coach of Northern Arizona Elite, one of the country's premier professional running teams, to let him train with a roster of national champions and Olympic hopefuls in the running mecca of Flagstaff, Arizona, leading in to the Chicago Marathon. The results completely redefined Matt’s notion of what is possible, not only for himself but for any runner. Filled with a vibrant cast of characters, rigorous and quad-torching training, and a large dose of self-deprecating humor, Matt’s gripping account of his “fake pro runner” experience allows us to partake in the dream of having the chance to go all the way. Yet for the gifted young runners Matt trains with, it’s not a dream but concrete reality, and their individual stories enrich this inspiring narrative. Running the Dream pulls us into the rarified world of professional running in a way we can all relate to, regardless of speed, and to take away pieces of one man’s amazing journey to try to achieve our own potential.
