2.8/ 10
Beginner-friendly
Moderate evidence confidence · 78% evidence coverage
This score is driven most by balanced overall demands. 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 largely runnable, non-technical surfaces.
trailcoastalroadmixednon-technical
Climbing density
4.1m 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 10h, the raw average required is 10:39 per kilometre (17:08 per mile), including every stop.
Raw pace10:39/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?
A realistic target for a prepared runner with some trail or ultra experience, but not the softest possible introduction to the distance.
6.2/10 suitability
Navigation
partially marked
Do not assume closed-road-race levels of signage. Know the organiser’s navigation requirements and keep the official route available.
Exposure & kit
unknown kit
Night running is not expected for most entrants based on the current format, but final kit rules still take priority.

Data PartialThe course uses arrows and race-team direction between checkpoints rather than a claim of full marking. The official entry confirms the ten-hour limit, £75 fee and 290 solo places. The organiser-linked route supplies an approximate ascent and a 33.6-mile measurement that conflicts with the marketed 35 miles; no exact aid-station count is inferred. The two-person relay is a companion category, and no unconfirmed 2027 successor is created.
