Now try changing the direction. There's a 2.8mile off-road route, but it'll send you on an 8 mile trip via the A14 (practically a motorway). Depending on the time of day, this requested route will even take you there and back between two junctions on the A14! Yes, the starting point is contrived because I know it's next to a bridleway (though it does involve crossing various bits on the A14 on foot - this being an officially signposted path).
