I am not a runner and I often wonder why people choose to put their bodies through grueling marathons. This book explains that very question in a charming and simple way. It was a joy to read, and made me truly understand the "need" some people have to run. And, in all honesty, I wish I had that kind of "need" because I got to be a little jealous of the time explained as "solitary time to think". About now, I could use some of that. The idea that the discipline of an activity like running carries over into the discipline of others areas of life (work ethic, etc.) is something we are all familiar with, but it never hurts to have that idea reinforced. This book also does that, very subtly and very well.
