A similar experience is available to anyone who has a bike, but no smartphone.
Try following the National Cycle Network signposts. If you're lucky you'll encounter nothing worse than a rough track with massive flooded potholes. I finally gave up on NCN when my route was signposted across the middle of a ploughed field. It would have been impassable even on a mountain bike, and I didn't fancy arriving at work caked in mud.
