Old Chalk Way

A bike packing journey along the route of Britain’s oldest highway from Dorset to Norfolk, from the English Channel to the North Sea, this 575 km route has been designed to explore Britain’s most ancient highway joining the Dorset and Norfolk coasts - designed by Ben Wormald and Chris Hunt at BASE magazine.
The route can be divided into four individual trails: the Wessex Ridgeway, the Ridgeway, the Icknield Way and the Peddars Way. Together, these linked routes traverse more than five hundred kilometres of rolling chalkland passing through 11 counties and visiting some of the most impressive and best-preserved prehistoric sites from Stone Age long barrows and Iron Age hill forts to stone circles and sculpted chalk figures.
