Route: Wimpole Way (United Kingdom)

Route follows the Wimpole Way from Cambridge to Wimpole Hall, and is well marked throughout (note that the route can be done either way, I don't think there's an official direction). There's no clear start or finish in the route descriptions, so one end is the front of the Great St. Mary's Church, Cambridge, and the other the south entrance door of Wimpole Hall.  

The route itself uses mostly public rights-of-way, with a few road sections, and passes through some pretty nice farmland and woodland remnants.
