I have a box of various maps and guides along with several regional guidebooks from a range of sources, including Bike Maps own guides to the Peak district, which are really clear and useful. So having one book with 500 mountain biking areas in it for England and Wales is an excellent idea and this guide does not disappoint. As well as providing routes for local areas, the guide has come in handy for finding routes in new areas I did not know about. It's also really motivating and makes you just want to get out and discover these great new routes! The book is clear, concise and practical, with straightforward easy to follow maps and instructions, including details of where to park, pubs, cafes, and trail conditions and gradients. Really useful features are atlas style maps with all the areas marked and the mini area maps showing where the route is in relation to major towns/villages. Trail centres are also covered, with a description of facilities and route gradings. All in all, at over 600 pages, this book offers incredible value with enough in it to keep all riders of all abilities satisfied.
