Episode 4

On the last leg of their adventure, Dan Walker and Helen Skelton are in the north Pennines, an Area of Outstanding Natural Beauty close to Helen's Cumbria home. Helen introduces Dan to one of her favourite Cumbrian villages, Dufton, where she joins a local running club on a steep fell run up Dufton Pike. Dan heads to Slaggyford, where he takes a ride on the South Tynedale Railway - the highest narrow-gauge railway in the north of England, with spectacular views for all five miles of the journey.
