Race For You difficulty
4.9/ 10
Moderate
Moderate input evidence · 68% evidence coverage
The main recorded demands are exposure and self-sufficiency. 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, exposed moorland where weather can amplify the difficulty.
trailmountainmoorlandmixed
Climbing density
29.8m 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 18h, the raw average required is 12:52 per kilometre (20:41 per mile), including every stop.
Raw pace12:52/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.
Who this suits
First ultra?
There is not enough verified information to assess first-ultra suitability yet.
Navigation
self-navigation
Route-finding is part of the challenge. Carry the required mapping tools and be able to use them in darkness and poor visibility.
Exposure & kit
unknown kit
Significant overnight running is likely for many entrants. Lighting, temperature management and sleep strategy can materially affect the outcome.
