This is a 100km fully supported race along the oldest path in Britain, the Ridgeway. The start line is in Oxfordshire and the finish line is next to the Avebury Stone circle, a Neolithic monument 5000 years old.
It has two categories: non-stop and 1 or 2-day stages. The 100km non-stop has a cut-off time of 36 hours.
The route to the Avebury Stone circle, the largest Neolithic stone circle in Europe, crosses Lewknor, Goring and the North Wessex Downs. Along the way participants run past Bronze Age hill forts, Neolithic burial chambers and Roman river crossings.
The registration pack includes: race number, luggage label, wristband and timing chip. The route is mapped and signposted, and pit stops can be found approximately every 10km.
