The Ridgeway is thought to be Britain’s oldest road, in use for at least 5,000 years. It is one of the trackways that used to run along the dry higher ground in ancient times. The Ridgway, in its modern trail form, covers 87 miles from Avebury, Wiltshire, to Ivinghoe Beacon in Buckinghamshire. There are various prehistoric remains along its route. In its original form, it stretched from the Dorset coast to the Wash.
