The late Christopher Knowles organised walking holidays in the Cotswolds for 25 years, and was the founder of Cotswold Journeys. Daniel Knowles now runs the family business and organises popular holidays for walkers from all over the world. He comprehensively revised his father's book in 2025 after rewalking all three itineraries that his father originally devised. Christopher's expertise on the region was reflected in his published books. For many years he had travelled professionally around the world, particularly to Italy, China and Russia. His account of travelling by train between London and Hong Kong in the 1980s 'The Red Line: a train journey through the Cold War' was published in 2017 by Pen & Sword.
