The Longest Walk

It's rambling, but not as we know it. Every year the Long Distance Walkers' Association organises a 100 mile walk. It has to be completed in 48 hours, which for most people means walking through two nights with no sleep. By the end, hallucination is common, and many of the 500 who started out drop out or by the time they finish can barely walk any more. Lives in a Landscape follows two participants in this year's walk, from Wadebridge in Cornwall to Teignmouth in Devon. One, George Foot, is 76, and has done 24 100-mile walks already. The other, Josh Wainwright, is 18. This is his first 100. Will either of them complete the walk, or will they have to "retire" early? As George walks, he talks to presenter Alan Dein about his long-dead father - a distinguished public school headmaster. It becomes clear that George has spent much of his life in his father's shadow, feeling that he was a permanent disappointment to him. As a child, George was told by his father that he was "a bad walker". Now, completing the 100 mile walk is a way of redeeming himself in his father's eyes. Josh, on the other hand, is walking the 100 miles with his father, Dave, a 21st century parent. Will Dave be more forgiving of failure, and more willing to praise success? An exploration not just of the challenges of walking and endurance, but of the changing nature of fatherhood. Producer: Jolyon Jenkins Presenter: Alan Dein.
