I really liked this book. It did two things for me: 
 1. Convinced me to use Vibram 5 Fingers. 
 2. Got me excited about running... an impressive feat at the time. 
 Still, at the end of it, I am not sure I can really comprehend the idea of running 100 miles. I balk at the idea of driving 100 miles. That said, I liked how he told the story, and I would recommend it to anyone who is into running.
