Britain by Bike with Larry and George Lamb

Larry is able to indulge his passion for Roman history as he and George cycle along a section of Hadrians Wall and visit the Vindolanda archaeological site. They also spend a night in a haunted castle.

The pair load their bikes on to the Paddington-Penzance sleeper train and after taking a ferry across the Celtic sea, they head to the island paradise of the Isles of Scilly.

The Lambs challenge each other to a race through Britain's first ever National Park, join the World Hen Racing Championships, and indulge in the local tradition of springtime sheep-washing.

The Lambs spot seals around Stangford Lough, enjoy Guinness and oysters, investigate their family history and play the bodhran at Northern Ireland's oldest thatched pub, the Cross Keys.

Larry and George tackle the Hebridean Cycle Way, en route meeting a weaver of Harris Tweed, having a kick about on one of the world's most spectacular football pitches, before enjoying a bagpipe lesson from the Lewis Pipe Band.
