This book provided a decent story about the history of one of America’s top running coaches, but it doesn’t provide much information for someone looking to gain information on training. The author keeps repeating the phrase “running on the edge”, which is just the author’s way of saying that the runners were doing tempo runs. Bob Larsen was ahead of his time when he had his runners doing tempo runs back in the 70s when most coaches were only doing high intensity intervals, but it seems that Bob’s coaching style is pretty common now. The book does provide some nice history of the long distance running scene in the U.S. over the last 40+ years.
