(What I have to say only concerns the Danish edition, because I have not seen the English, but I reckon that they're not that different.)
I'll start by saying that this is a okay introduction to running, but the book cannot stand on it's on. If you want to take running to the next level and do seriously, I recommend picking at least one more book up about running, preferably one that a bit more, well, thicker and reliable.
The reason why I only give this book 2.5 stars, because the author(s?) cannot figure out if they want to appeal to the general public, people who has not exercised in years or serious runner. They go from running in 10 minutes to running 10 kilometres on the same page. This can be because there were more than one author or because in their eager to appeal to everyone, they have tried to something that they just couldn't do within a book with a size smaller than an A5 page and only a hundred of pages. This book also cannot decide if it's readers have been exercising forever or never before, they continue to use bigger words than necessary. The point of the book should be to make running and information about running accessible easier and using technical terms that a completely unnecessary does not help anyone.
Also, the books also has a lot of pictures of people running - but only one picture of an old person and one picture of a group of people have average body build. The rest are of fit and more or less beautiful men and women. That also defeats the purpose of making running look accessible to people who tends not to exercise.
That being said, it can still enlighten you about the basic information about varies things when it comes to running.
It's been a couple of years since I last went running so I figured reading this would be a good refresher for me to get started again. While, it does cover all the basics and promotes for beginners the importance of a running plan the book doesn't cover everything! There is much more in terms of diet and potential hazards, i.e. Runner's trot among other things, which the book could and should cover!
However, the book is still a useful guide and, certainly, it is better for a beginning runner to have some guide opposed to no guide; what I am saying is the book should only be used as an induction guide. Therefore, If you decide to keep running and as your running routine reaches a higher level you should seek guidance from a higher source. The injuries I've suffered from running came about because I was complacent; it definitely pays to be well informed on how to maintain a high level of running.
While this book doesn't tell you everything it is still a clear and concise guide to start with.
