The Macmillan Way is a route devised to raise funds for the Macmillan Cancer Relief fund. It starts in Boston and runs south west for 290 miles to finish in Abbotsbury, Dorset. The Lincolnshire section runs along sea banks and river banks across the Fens to Stamford and thence on into Northamptonshire.
