recomend the Balmoral Hotel in Moffat for one of your stops (keen to encourage bikers to stay with them, every road out of there is truly class and lead onto others which are just as good, the routes you take depends how much time you intend to spend on the bike but off the top of me head I can think of an alldayer through that'd end at loch Lomond on nothing but truly awesome roads both in terms of scenery and riding. Note to self - must do that run sometime, in the mean time keep it to myself . oh and I'm sure we could find you a corner of a field to camp in not sure I'm going to be able to do lejog or a trackday this year, in which case I'd be happy to guide you on one of the legs of your trip
