5.2/ 10
Hard
High input evidence · 88% evidence coverage
The main recorded demands are high climbing demand, technical terrain. Course difficulty and cutoff pressure describe different challenges: more approachable terrain can still require a demanding pace to beat the deadline. Neither score assesses your personal fitness, safety or readiness.
Scoring details and version
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. Evidence coverage describes the recorded inputs, not prediction accuracy or your likelihood of finishing.
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
64.9m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
High pressure
To finish inside 14h 30m, the raw average required is 15:16 per kilometre (24:35 per mile), including every stop.
Raw pace15:16/km
PressureHigh 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.

Data PartialThe official 2027 page and entry verify 57km, 3,700m and a 14.5-hour 06:30–21:00 window. An older 07:00 paragraph conflicts with the current timing panel, so 06:30 is used with explicit monitoring.
