I'm an avid runner and do most of my training/racing on roads. Thought I'd pick this up to get some info on converting to trails or at least running more on trails. I will still do so, but not because of having read this book. The only information of value for me was the section on animals and what to do when you see them. Ie. Grizzly vs Black bear, etc. Other than that, the authors make it a point to put down road-runners at every chance they can get. From footwear and clothing choices, to attitudes and mindsets-these authors clearly feel that they are better than your average road runner. Most of the trail runners I know are easy-going, laid-back, and very likely to help anyone out--definitely not the snarky Chase and his co-author. However, having said all that, if you are a beginning runner and can ignore the unnecessary side-bars, you could gain some general running knowledge from this book.
