Jeffrey Horowitz didn't expect to fall in love with marathoning, but that's just what happened. He had never run a race, was not on his high school track team, and had never owned a pair of running shoes. Then, in 1985, he went out for a run and it changed his life. Eighteen years later he completed his one-hundredth marathon. This book is Jeff's story, but it is also the story of everyone who loves to run. It includes his training, his injuries, his best times, his joys, his friends, his failures. In some ways, it's an unusual story. How many other runners have finished 100 marathons? In other ways, it is the story of every runner who has found joy and satisfaction in a training routine, in reaching a goal, or in finishing a race.
