If you are interested in the science of running and history of running etc, this is a great book - very large having a lot of wisdom. It is not my favorite book - Which to me would be more the Daniels Running Formula - then is more concise and to the point with training pans etc ...
But as I said if you want to understand running and just learn lots of interesting facts about human bogy When exercising, there is no better book than this - unless you then go to study Exercise Physiology in the University.
