Dean Karnazes is an exceptional man, let's first acknowledge that. This is not just because he is probably the ultimate endurance athlete of our time, but also because he is not so full of himself like many other athletes who are payed with real money for winning races rather than by belt buckles (as the traditional price for most ultras).
This is probably not as ground-breaking of a book as 'the Ultramarathon Man', Karnazes's first book that was a NewYork Times bestseller, but it is a great book never the less. The major difference I found is that this one doesn't have to try as hard as the first one had. The first one had to introduce the man (Karnazes) and the concept (Ultramarathon) to an audience largely ignorant of both, it had to cram a lot of information to make sense and it had to be convincing.
This book doesn't have to work as hard. It is like a new conversation with an old friend. No need for introductions, the chat can flow from where you left last time, and you can go here and there. In this book, Karnazes didn't repeat the same stories of the first one although some of them get mentioned, he still talked about some amazing races such as the 4 deserts race and the 48 hours attempt to break Guinness world record, but he also had the time to talk about his family, about his life, and about his friends. As an increasingly aspiring runner, I find the parts about Topher Gaylord most inspiring... in a way, one cannot compare themselves to Dean, he has got a gift that not many of us have, but I can compare myself to Topher, he wasn't a born runner but a made one, he started late, he had skinny legs that barely held him, and he now runs 100 mile races.
For me, this book was entertaining, inspiring, and the story of Topher made me think... if spaghetti-legs can do it, so can I...
