Ultramarathon Man: Confessions of an All-Night Runner by Dean Karnazes is a great read.
very much enjoyed Born to Run: The Hidden Tribe, the Ultra-Runners, and the Greatest Race the World Has Never Seen by Christopher McDougall
im half way through Running with the Kenyans: Discovering the secrets of the fastest people on earth by Adharanand Finn which is great so far.
All the books make me want to run crazy miles!
