This book seemed like the perfect choice because it offered a very gradual approach to build up your running. The content was great, it offered a lot of good background not just on running but on nutrition and preventing injuries, that are applicable to Judo as well. In addition to the beginner's programs for running and walking, it also provides you with step-up programs to maintain and improve your running, as well as good training advice for building up to a marathon and half-marathon.
However the jury is still out on the program and its long-term benefits. Still if you are thinking about picking up running, and don't know much about it, I would reccomend this book as a good starting point.
