This is the cycle friendly opening 43 miles of The Ridgeway - one of the UK's National Trails.
This section runs from Overton Hill, near Avebury in Wiltshire, to Streatley, in Berkshire, on the River Thames. The path passes through some lovely scenery including rolling downland and the woods and valleys of the Chilterns. Highlights on the route includes Wayland's Smithy - a Neolithic long barrow and chamber tomb, and the Uffington White Horse in the Berkshire Downs.
This ride is only really suitable for mountain bikes, taking place on an off road track from start to finish.
