Wow. Much like a good hike, this book started off great and just kept getting better, all the while taking twists and turns through beautiful country. McDougall weaves a saga of adventure, curiosity, honor, compassion, and joy; all while educating the reader of a long-forgotten part of our heritage. Gripping, even to this not-quite-avid runner. Highly recommended for anyone who runs as well as anyone who doesn't.
