I imagine from the book, that you wouldn't want to walk with Brian Smailles. Essentially he is a marathon walker and, from the book, you sense an obsessive personality. The book is not especially well written, in places is dull and some of the advice pretty ridiculous.
Nonetheless it was essential on the coast path. In a lot of places the path is poorly signposted and Brian is meticulous in providing detail to make sure you stay on the right route. On at least a couple of occasions we would have been heading in the wrong direction without him. So, thanks Brian, and in the absence of an interesting guide to the coastpath, buy this one.
