I have been running for two years and have read a few books about running, primarily beginner running books. This book does offer some good advice about training as a whole. But I think it is more geared to the serious and / or competitive runner rather than just the casual runner. For the record I typically run 5k races in the Spring, Summer, and Fall, and my times are generally in the 25-27 minute range.
The approach offered as a whole will help me. I really feel like I'm "training" now rather than going out for a run. Varying the running distances, speeds, and hill / strength training has already boosted my performance after three weeks.
But I just found the whole "adaptive" running thing, that is to run how you feel, to be impracticle. I think it may be good advice for a college athlete or someone with a lot of time on their hands. But if you're a working professional like me, you have about 45 minutes a day to work with. I've got to get certain workouts in on certain days. Also, I'm more of a routined person. I like to do certain things on certain days.
I just found the overall tone of this book to be much more geared toward the true running junkie, the ones who run the 5k in 16 minutes, versus the casually competitive runners like myself. Some of the training recommendations are great, I just didn't have a use for about 3/4's of this book.
