Following single track 'military' roads from one side of the stunning Scottish Highlands to the other Peter and Chris retrace the route of the 1930s petrol head pioneers into some of the UK's most extreme driving country. Along the way, they fire up a 1903 'Dog Cart', take a spin in a vintage 3-wheel Rally Car up the notorious Inverfarigaig Cork Screw and cross over to Skye on the oldest car ferry of its kind in the world.

Peter and Chris set out from London to motor down the entire length of the A30, originally an 18th century coach road that runs for nearly 300 miles of ever-changing English countryside before it reaches Cornwall and Land's End. Along the way they recreate Britain's first recorded car journey in a 1900 Georges Richard, climb about one the UK's first haulage trucks and recreate the roadside picnics of Peter's youth.

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.

Chris and Peter explore the beautiful Borders countryside, driving from Edinburgh to Hadrian's Wall, and meet some motorsporting heroes. Peter takes an exhilarating ride with a champion rally driver.
