Last year we completed our walk of the full length of the South Downs Way and we are now about halfway through walking The Ridgeway. We anticipate the walk taking 3-4 weekends and will use rail travel to get there and back from Surrey, leaving our cars at home, and carrying with us the minimum necessary for an overnight stay in a pub or B&B.
This is my map showing train connections, overnight stops and places where we found refreshments on the route:

Further details can be found here and I will update the map and blog page next we as we progress towards Ivinghoe Beacon.
