High input evidence · 88% evidence coverage
The main recorded demands are balanced overall demands. 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 0.35 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. Evidence coverage describes the recorded inputs, not prediction accuracy or your likelihood of finishing.
Selected-edition source check · 2026-09-08
The retrieved organiser page records 15 November 2026, 50km, 1,145m ascent and a 9-hour limit. Both route options share the £69 fee after the early-bird period, plus an online entry fee whose amount is not established here. Equal recorded fees do not produce a unique cheapest race. The cached page’s August entry-opening announcement is not a new opening observed on this review date.

Course analysis
What shapes this race
Expect forest trail that may change character in wet conditions, largely runnable, non-technical surfaces.
trailforestroadmixednon-technical
Climbing density
22.9m 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 9h, the raw average required is 10:48 per kilometre (17:22 per mile), including every stop.
Raw pace10:48/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?
One of the more approachable options in its distance bracket, provided you prepare for the full distance and practise the required kit and pacing.
