Gravel Biking - Cycling/Bikepacking the Ridgeway from Ditching Beacon to Avebury We decided to test out Marin's new Four Corners bike and some custom Restrap bags by riding the Ridgeway - Britain's oldest 'road.' The 90 miles long Ridgeway is a National Trail that runs from Ditchling Beacon to Avebury passing numerous neolithic sites such as long barrows, hill forts and a 3000 year old chalk horse. It's largely off road.Unfortunately Avebury itself isn't in this video but if you've not been you must go, it's INCREDIBLE!!!
