The route is one lap (Half Marathon) or two laps (Full Marathon) and starts and finishes at the main building inside Denbies Vineyard near Dorking, Surrey.
The route is undulating (with one significant hill) and multi-terrain with a bias towards road. Half of the course is inside the beautiful Denbies Wine Estate, the other half passes through National Trust countryside and woodland along the Pilgrims Way and North Downs Way.
It is a demanding route but also a beautiful one offering breath-taking views over the Mole Valley, Ranmore Common and the North Downs. Although some runners choose to run it as quickly as possible, most take a lighter view of the day and take their time to make the most of the sampling stations along the route.
The course is traffic-free but there is one crossing of a major road which will be policed by marshals. The route is clearly marked and signed along the way and there will be marshals at all key turns and junctions. The marshals are there for your safety so please pay attention to any instructions they give you.
