Not sure about getting to Sedbergh but from there there’s two BWs: one from Millthrop over in to Dentdale and one over Frostrow to Dent. From there, a mile or so of road gets you on to the BW over Great Wold to Ribblehead. Road to Selside then follow the Pennine Bridleway over Sulber Nick, past Austwick, through Feizor and Stainforth. From here you’ve a choice:
1. When above Stainforth cut up past Victoria and Jubilee caves on the Settle Loop and head over towards Malham, don’t drop to Malham itself but go towards Malham Tarn then pick up Mastiles Lane. A little way along this turn R to Lee Gate and Weets Top, down to Calton then Airton, Bell Busk and Gargrave (should be obvious to follow the BWs and short bits of joining road on the map). Follow the Leeds Liverpool canal towards Barnoldswick and pick up the Pennine Bridleway again.
2. Just follow the Pennine Bridleway all the way.
When you reach Widdop, take the Calder-Aire link eastwards.
