If you thought the Trollers was good have ago at this one ....
Nr Otley West Yorkshire, starts close to Fewston Res, over Roundhill and beamley beacon, down to bolton Abbey, then back over the moors to Thruscross REs and back down the river washburn to teh usual feed at the end - 25miles (no shorter) with about 4000ft of climb. Did it in just over 4hrs last year.
Much more satisfiying than the boring old Baildon Boundry Way - on the same day
