4.3/ 10
Moderate
Limited evidence confidence · 48% evidence coverage
This score is driven most by balanced overall demands. Difficulty V2's separate time-limit modifier adds 0.35 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.

What shapes this race
Expect forest trail that may change character in wet conditions, exposed moorland where weather can amplify the difficulty.

Cutoff analysis
Very high pressure
To finish inside 9h, the raw average required is 10:10 per kilometre (16:22 per mile), including every stop.
Raw pace10:10/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.
Because ascent is not verified, Cutoff Pressure V2 uses the model's neutral 20m/km reference density. This assumption does not fill the ascent value or make missing evidence look easy.
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
Night running is not expected for most entrants based on the current format, but final kit rules still take priority.
Personal race predictor
Prediction unavailable
No current compatible predictor target is available for this family. The selected edition may be complete or cancelled, awaiting a successor, non-standard, or missing model-critical course evidence; older facts are not substituted.
