Course and logistics
The main route runs on and around Box Hill, with registration and parking at Denbies Vineyard and the race start at the bottom of Box Hill. The finish is at Box Hill Fort at the top of Box Hill; participants parked at Denbies need to walk back to their cars after the race. If Box Hill cannot be used, an alternative "B" course around Denbies Vineyard will be used; that alternative course is about 12.5 km.
The course is largely on rough tracks and includes steep, slippery and muddy sections. Headphones and earphones are not permitted on the course. There is a water station at 6 km. Prize-giving covers the top three men and top three women, and there is a separate prize for the first woman home. Marshals are requested for parking, course signalling and finish help; marshals are provided soup and rolls and a future race place. Visit the organization's website for the most recent information.
