Hello, I have just bought a load of the Sustrans Cycle route maps, and one of them is for the route between Glasgow and Carlisle via Ayr and Dumfries, etc (route 73) This is ok, but there appears to be another more direct route, a route 74, from Gretna to Glasgow via Lockerbie that isn't shown on it. I can look it up on the internet, yes, but what is this route like? and where in Glasgow does it go to?? I'm curious. Thanks.
