Helwith Bridge to Wharfe, follow Pennine Bw to Cam Fell then the Roman Road to Bainbridge. South to Buckden across Stake Allotment. Road all the way up Langstrothdale then across to Horton and back to Helwith. 45 miles. Nothing technical, a few rocks here and there, very scenic.
Came here to say something like that.
Follow the watershed around Raydale and extend it out to Ribblehead. The only bit I’ve not done is the section from Langstrothdale across to Horton and I don’t recognise the outbound description?
My loop would have been park at ribblehead, there’s a footpath (it’s not a footpath, it’s a gravel road that becomes a bridleway after about a mile) then becomes the Cam road, round the bottom of Semer Water, take your pick of either of the bridleways out the other side (Stallingbusk is all rideable, the other is a bit steep in places then flattens out over the top, but neither is technical, down the other side, turn right, lunch in the pub, carry on and take the bridleway back to Helwith, and then road back to Ribblehead (there may be a better option than the road).
