The Chiltern Wonderland 50 is a 50 mi single loop through the Chiltern Hills, starting and finishing in Goring on Thames, Oxfordshire. The route covers 5600 ft of ascent and the same amount of descent, and follows parts of the Thames Path, the Chiltern Way and the Ridgeway while passing through villages and landmarks such as Mapledurham, Stonor Deer Park, Turville and Christmas Common (highest point on course, 800 ft). The course surface is approximately 80% trail and 20% road and is fully marked with Centurion ribbons and arrows.
