My First 100 Marathons

When Horowitz went out for his first run in 1985, it changed his life forever. Eighteen years later he completed his 100th marathon. This is his story, as well as the story of every runner who has found joy and satisfaction in a training routine, in reaching a goal, or in finishing a race.
