The Scottish Highlands

Clare Balding's two-wheeled odyssey to re-discover Britain by bicycle hits the Scottish Highlands, uncovering a series of vivid human stories connected to this stunning landscape.

Clare is following the wheeltracks of compulsive cyclist and author Harold Briercliffe, whose evocative guide books of the late 1940s painted a picture of by-passed Britain - a world of unspoiled villages, cycle touring clubs and sunny B-roads.

Carrying a set of Harold's Cycling Touring Guides for company and riding his very own bicycle, Clare goes in search of the world he described and charts how a series of incomers have changed our view of the Highlands - a diverse group which includes Dr Johnson, an English army of occupation, a North American spruce tree and author Gavin Maxwell, plus otter.

And for those wondering whatever happened to TV naturalist Terry Nutkins, the answer is revealed.
