In 1980 Mark Richards began his three-part guide to the Peak District for Cicerone Press, and in 1987, with Chris Wright, wrote a guide to walking around the former county of Westmorland. He now lives in Cumbria and, after 14 years' dedicated research, has completed his series of Lakeland Fellranger guides covering the entire region. He has also written a guide to Hadrian's Wall.
