The last few times I've ridden to Hamsterley along the A68 have been a bit scary, especially when windy. So here's a map of my new route to Hamsterley, which uses quieter roads. (Mainly so that I can find the map again.)
I'll probably try it out on Sunday, to get to the Trailblazers' group ride.
Update: I've now mapped it on Bikely, so height data will soon be available. Bikely: Darlington to Hamsterley Forest
