Though I have read very few pop culture & philosophy books all the way through, this is one of the best ones I have read. Not only do many of the essays connect to well known philosophers and ideas, but many other essays seem very original in their thesis and their conclusions. The best part about this book, though, is that nearly all of essays are easily relatable as anyone who has ever done even a short mile or 5K race can instantly understand what the author is talking about when they mention something about running. It doesn't hurt that many of the best authors seem to be runners themselves and imbue their essays with their own personal experiences. However, at times the book suffers from what many pop culture & philosophy books suffer from: essays and ideas that are not explained very well and go way over the heads of the readers. One essay in particular started talking about "zombies" without explaining what he was talking about. It took me half of the essay to figure out what he meant. Overall, while this book won't make you a better runner or be as necessary as a good pair of running shoes, but the topics discussed will keep you thinking on those long runs.
