Clare joins a long established group as they embark on their 100th walk. Their route takes them from Leigh Woods, under the Clifton Suspension Bridge, and into the heart of Bristol. They call themselves The Old Lags, and every member was responsible during their careers for keeping our lights on and our kettles boiled as employees of the Central Electricity Generating Board. They’re all retired now and David Miller, who runs the Old Lags, is certain they’d have lost touch had it not been for their shared love of a good stomp.
