The route is a combination of bits and pieces (I’ve not ridden it all together) and comes in at about 30 miles with 1500m of climbing.
Mind you, the length does depend on how many loops of the quarry you do! 🙂
I might be inclined to go down Gin Croft Lane if it’s not icy – that would cut out a climb and some pushing near the top of the Coal Road.
Wors, I’d go for the anti-clockwise loop, come over on the canal via Radcliffe and finish via Moorbottom Lane to Crowthorne.
That would be a good ride!
