Terrain & grades
96% at ≤15% gradeThis loop packs 29m of climb per kilometre, which makes it a relatively flowing profile. 96% of the measured line is at 15% grade or less (slope only, not surface or technicality). The hardest kilometre is around km 20, gaining about 153m. Total route distance is 101.0 km.
Snow & conditions
Snow not assessedCurrent snow evidence is not available for this route. Missing data does not establish snow-free conditions. This route reaches 3033m, where seasonal snow may linger.
Route sections
Epic effort, about 25h 49m moving time as the Planner estimated it when the route was saved, for 2876m of climbing. Expect 1% steep-grade exposure.
Fuel & gear
Plan roughly 139 small fuel units, then adjust for weather, aid, and personal effort.
Surface
OpenStreetMap tags the surface on 96% of this route; the rest is classed by its road type, an estimate.
Path difficulty, as tagged in OpenStreetMap
- T1 hiking: 7.3 km
- T2 mountain hiking: 22.2 km
No difficulty tag on 54.5 km of path or track: unknown, not easy.
The SAC hiking scale mappers give each path. It is not a check of exposure, the weather or snow on the day.
On roads with traffic: 1.2 km in 4 stretches (the longest 400 m). Roads of class tertiary or bigger in OpenStreetMap; crossings and stretches under 100 m are not counted.
