OK, the Official January WARTY Ride is to celebrate Annie's birthday, which is on Friday. We are going out Saturday 10th Jan here. ...
Since Wowbaggers map is a bit chunky, and doesn't work ideally with my Active-10 GPS (which will just overlay the GPX onto the OS mapping), I took his map, re-input it into Bike Route Toaster using the Auto-Route following bit, then output it and simplified it using GPS Babel.
This map follows the route a bit closer, but has 300 data points. This is OK for the Active-10, but may be a bit much for other GPS's, unless you want to follow the route more exactly, and don't just need junction information (which Wows provides adequately).
I think I've gone on the correct roads, but occasionally I've had to make an executive decision and pick one road over another, but I doubt it matters much. The total distance using this, which follows the route a bit more closely is a smidgen under 50 miles.
