This is the one. Being a naturally cautious boy, I initially bought the Runner's Handbook. This one is a considerable improvement - it repeats much that is in the original; however, unless you're the kind of runner who can't manage more than a run down the end of the road, you should ditch the first book in favour of the Competitive ... It has all the useful information contained in the previous version, and then a lot more that will help you move up a level, whether you're low or mid-intermediate. Any higher than that (ie if you're looking at sub-40 minute 10kms, etc.) and I suspect you already know what you're doing and you're not looking to buy a book like this, although you may find some useful tips. Stretching, injury, different programs for different distances and different types of runners; ideas on how to run on various types of terrain; in different weather conditions. It's all there, and not only are the sub-chapters there to answer any question you might have but, most importantly, it's well written and intelligently done. There is very little filler in this book. There are very few annoying Americanisms and little wasted space - every chapter serves a purpose, is well constructed and leaves you with a bit idea of what you're trying to achieve. A great buy amidst the wealth of running books available.
