I'm thinking i'd like to walk from London to Edinburgh fairly soon. I estimate i could do it in 7-9 days, not particularly bothered about rushing through it quickly.

I'd like to pass through some nice small villages, and walk through a few larger towns too, and see a lot of lovely countryside.

Is there an established route? How would you do it if you walked it? I'd rather not walk alongside big roads for too much of the time, and the police tend to pick people up who are walking alongside motorways (i'm a long-time hitchhiker and have walked fairly long routes in the past fully laiden)
