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 4 starts at the Fox and Hounds pub in Christmas Common, and passes through Stokenchurch and Radnage, and finishes at the Hampden Arms pub in Great Hampden. Kop Hill featured in the 2014 Tour of Britain and hosts the annual 2-day Kop Hill Climb for classic cars and motorbikes. Don't be fooled by the gentle ramp at the start; it gets worse, and then much worse, as you approach the top.
