I threw this together but it's actually pretty good. It's a Mapbox wrapper that overlays long distance hikes (Pennine Way, Offas Dyke, Yorkshire 3 peaks, any others), the project is structured with sourcesets so making new variations is trivial, all that's needed is the geo data. I used it while doing a couple of multi-day sections of the Pennine Way and it was invaluable.
