This is one of the best nonfiction books I've read this year.

Starting with the basics: McDougall's book begins as an exploration into running injuries, but is really about three interweaving themes: Ultramarathon running; the Tarahumara people; and barefoot running.

I was most impressed by *how* McDougall tells these three stories. They're all interconnected, and I had the sense that the book works like waves crashing onto the beach - each wave overlaps the ones that had come before, mixing and making the previous wave reverberate. It's a truly impressive writing job.

And it's a fascinating story, and inspiring, and very entertaining.
