If you are thinking about doing this route this book is fantastic - Even giving you the gradients etc - Fore-warned is knowledge worth having when doing some cycling - This book tells you everything and I was so glad of it..... This area is absolutely stunning and this book gives you the opportunity to really understand where you're going before you get there giving you the time to adjust routes to take in some more of the sights which you would have missed if you had just done the A75 etc....
Despite being published in 2009 this book is very out of date. It does NOT cover all of the NCN in Scotland and the text - despite claims on the cover of a revision (in 2004) and amendments (in 2009) - often mentions what the author EXPECTS will be the case in 2000 (i.e. at least some of the text hasn't been revised since the first edition in 2000).
The current NCN network in Scotland is considerably greater than that covered in the book - routes along the west Coast, the Great Glen and the islands are not described despite being included on the Sustrans map dated 2009. I'd also be concerned about relying on mileage, gradient and accommodation information, too (for instance, the distance from Carlisle to Gretna is a little over half that claimed by the author).
I think that the descriptions of places are impressionistic and could have benefited from being better researched or left out all together. Churlish I know, but a decent sub-editor might have at least added consistency with capitalisation of the map annotations.
This book may have been a labour of love for the author, but it's title and cover are misleading. It's also heavy - nearly 400gms or about a pound - if you're touring.
When I bought the book I expected it to cover the national cycle routes in depth but it just briefly describes them. Really not enough info. In addition, it does not involve interesting cycle routes, eg. Aberdeen- Edinburgh cycle route passes Falkland and there are beautiful Lomond hills which can be climbed with the bicycle almost to the top. Some info is just misleading, like saying that the hill to Auchtermuchty from Newburgh is "painfully steep" which is not true. The book is printed in a way of leaving loads of blank spaces just to make it look thicker, more serious.
