The Ford at Little Lawford is 2.5 miles from my front door, I'm guessing the contours are at 10m intervals, so about 20-30 metre rise in about 200m once I turn round at the halfway mark (coming up past Clayhill Farm) and there is another dip where the little stream crosses, and that looks as though it's on the same contour as the ford...
