Method: DIN 33466 walking time — details.

Distances and elevation are computed from OpenStreetMap TMB geometry (main relation 9678362; alpine variants 9678380 / local hiking ways) and ASTER DEM via OpenTopoData. Walking time follows DIN 33466 (see /en/method). GPX is that OSM track plus listed variant tracks and stage/lodging waypoints — verify on the ground; do not navigate blindly. © OpenStreetMap contributors.
