7.1/ 10
Very hard
Moderate input evidence · 79% evidence coverage
The main recorded demands are substantial race distance, high climbing demand, 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 0.00 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, exposed moorland where weather can amplify the difficulty.

Climbing density
46.6m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
Moderate pressure
To finish inside 42h, the raw average required is 15:40 per kilometre (25:12 per mile), including every stop.
Raw pace15:40/km
PressureModerate 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
GPS required
The route is described as marked, but runners should still read the final race instructions.
Exposure & kit
extensive kit
Significant overnight running is likely for many entrants. Lighting, temperature management and sleep strategy can materially affect the outcome.
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.

Data HighThe official 2026 page verifies the Friday 14:00 start, Sunday 08:00 finish limit, 100 miles, 7,500m, 42 hours, £160, thirteen checkpoints and GPS-led outward leg. The 19-hour turnaround closure remains intermediate and is not substituted for the overall limit. Entry availability checked 28 September 2026: SI Entries states new entries closed on 16 September 2026 at 23:00. The event remains scheduled; closure is not cancellation evidence. Field-scoped check 2026-09-28: Official edition-specific SI Entries explicitly states new entries closed on 16 September 2026 at 23:00. The scheduled event remains future; the verified closure affects entry availability, not occurrence or cancellation. Only these facts were reviewed; other details retain their previous source dates.
