How we got the numbers
Distance and climb come from the line itself, with heights from the Copernicus GLO-30 elevation model (30 m) and climbing counted once the height has changed by 3 m: these are the figures the app shows. This route was added before we smoothed heights. In forest the model measures the top of the trees, so the climb above is probably too high: a rough smoothed estimate gives about 1,610 m one way (1,890 m there and back). When the route is rebuilt, the app and this page will change together.
Walking time follows the DIN 33466 rule used by the German and Austrian alpine clubs, on the figures above, without breaks. The difficulty is the rating the route was given by hand when it was added to the app. The rule we use for newer routes (the climb and the walking time of the whole outing, one level up when 30 % or more of the line is on slopes over 30°) rates it Very demanding on the smoothed estimate, so plan for that until the route is rebuilt.
33 % of the line itself runs on slopes over 30° in the elevation model; slopes above it are not counted. This describes the terrain, not today’s conditions, and it is not an avalanche rating.
