I was really interested in this and ordered it before seeing a copy in real life. I must admit I am disappointed as the ONLY roads marked on it are the suggested 'cycle suitable' routes. These are very few in comparision to the national network of normal roads and lanes. This is problematic as if you need to cut across country, go to an area or village not on a 'designated route' or if you need to change or connect routes from one recommended route to another. Any of these issues makes this map pretty useless, as no alternative roads are marked in, none of the general road network or country lanes. This is a crippling impractical feature, about as much use as a car atlas would be if it showed only motorways and no other routes at all.
I tried using this map in conjunction with a standard Ordnance Survey map, but the scales are different and the lack of info makes it quite hard to match in the 'cycle routes' with the general road network on a 2nd map, plus of course, you now have 2 maps to handle.
On the whole, I think its a great idea, but could have been executed in a way more aligned with real life route issues, instead of somewhat idealised cycle routes that have such hugely limited destination and route options.
I hope they re-think some of this and do a 2nd edition with the national road network included, and a load of towns and villages being included.
