Wow! This book lulled me into a false sense of security, and then came at me with such tour de force with its juggernaut ending. Fuel is crafted beautifully, and I found myself going back to re-read many of this author's words because of they way they were ingeniusly assembled. I'm huge into running, it's a very essential part of my life. This is one of the best, if not the best running book I've ever read. I highly recommend it to you running folk who love a good underdog story.
