The bastard grassy hill really isn’t that bad! Then again, I do have a granny gear…
I’ll dig out a Strava, but the best way of doing that, and about 15 miles, is to start at Clapham, climb the tunnels and Long Lane, then carry on to Thieves Moss, head around the top of Crummackdale and down all the way to Wharfe – top section will be a bit splashy at the mo though. Turn R when you hit the road, head to Austwick (pub), pick up the Tunnels and Bridges route to Feizor (cafe), and follow this back to Wharfe back up the singletrack but carry on up over the clapper bridge, up the BGHCOL and finish down Long Lane and the Tunnels.
