Pushing the mileage a little bit more but worth the extra time.
Climb out of Calne to Sandy Lane via Heddington and down towards Rowde.
Go through Bromham and and then out into rolling lanes towards Seend. Head towards Bulkington and around Keevil Airfield and back through Edington, Marston and Poultshot.
Go past the end of Caen Locks we retrace our steps back to Calne via Rowde.
