The stars of All Creatures Great and Small return to rural Yorkshire, travelling their own Herriot trail from Scarborough to the Dales, for a very special and nostalgic drive

Christopher Timothy and Peter Davison explore the Borders countryside, a region that has produced motorsport heroes. They travel from Edinburgh into Northumberland, finishing their journey at Hadrian's Wall. Along the way, they discover the story of a pioneering female car engineer, find out how a farmer became a motoring legend, and take a ride with a champion rally driver.
