Elevation loss

Elevation from the Copernicus 90 m terrain model via Open-Meteo; expect ±5–10 m on rolling terrain, so treat gain as a comparison between routes rather than a survey. Road routing by OSRM (car network — turn it off for trails). SAM uses the same 5-factor model as the app with your easy pace as the reference; heavier weight, surface and fatigue on long routes are applied the way the calculator does.
