MakeATrail plans running routes anywhere in the world. It runs entirely in your browser: map data comes from OpenStreetMap through OpenFreeMap vector tiles (with the Overpass API as a fallback), popularity from public OpenStreetMap GPS traces, and elevation from the AWS Terrain Tiles open dataset. The routing algorithm is our own.
Routes are suggestions. Check that paths are open and safe before you run.
