If you run, you should read this book. If you run but have no sense of human, don't read this book. This is not meant to be hardcore running advice, like Remy's other books, it's meant to be funny.
It was recommended to me by another runner and I'm glad I took the time to read it. The writing is witty and doesn't take itself seriously at all, written as though you're studying runners like birds by a man who's run so many marathons I can't keep track. It's a fast read, most pages having diagrams/pictures, I read it over two days because I refused to let myself finish the first day, and I was sad it was over so soon. I will definitely keep this book for anytime I need a light read or a laugh (planes, car rides). I also appreciated that in the end he recommends his other books, because I find it hard to find quality books on running, and I enjoy his writing style.
