5.4/ 10
Hard
High evidence confidence · 88% evidence coverage
This score is driven most by high climbing demand, technical terrain. Difficulty V2's separate time-limit modifier adds 0.15 points here and is capped at 0.70; a broad limit cannot erase extreme intrinsic demand. This is independent of the public Cutoff Pressure V2 band.
Weather, conditions and individual preparation can change the real difficulty significantly.

Course analysis
What shapes this race
Expect sustained upland ground and meaningful climbing, sections where foot placement and downhill confidence matter.
trailmountainfelltechnical
Climbing density
69.8m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
Very high pressure
To finish inside 15h, the raw average required is 14:17 per kilometre (23:01 per mile), including every stop.
Raw pace14:17/km
PressureVery high pressure
Cutoff pressure compares the published time limit with distance, ascent and verified course demands. Lower pressure does not mean the race is easy. Raw pace includes checkpoints, food stops, navigation errors and any sleep; it is not a pacing plan.
