The Chilterns Cycleway is a 170 mile/275 Km circular cycle route through the Chilterns Area of Outstanding Natural Beauty, taking in the best of the Chilterns scenery. It is signposted for both clockwise and anti-clockwise travel. It passes through Buckinghamshire, Oxfordshire, Bedfordshire and Hertfordshire, taking in some of the best landscapes in these counties and is peppered with many short, sharp climbs typical of the Chilterns, especially in the southwestern half. I have cycled it clockwise, in approximate 16 mile/25 Km sections. Section 5 starts at the Hampden Arms pub in Great Hampden, passes near to Chequers, the countryside home of the Prime minister, takes in a steep up-and-over through Dunsmore, and finishes at the top of Toms Hill Road near to Aldbury.
