Successful source check: 3 Sept 2026Source confidence: highThe organiser explicitly states 08:00-18:00 / 10 hours, at least three aid stations, substantial mandatory kit including a headtorch, and the current 2026 circular route from Beechenhurst towards Monmouth and Symonds Yat. The exact aid count and night exposure remain unknown. The 2026 ascent is unknown; the 2025 UTMB record gives 1,300m, but the route changes each year so that value is not carried forward.

Race For You difficulty
4.1/ 10
Moderate
Moderate input evidence · 62% 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.
Weather, conditions and individual preparation can change the real difficulty significantly.

What shapes this race
Expect sections where foot placement and downhill confidence matter, forest trail that may change character in wet conditions.

Climbing density
23.6m 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 10h, the raw average required is 10:55 per kilometre (17:32 per mile), including every stop.
Raw pace10:55/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.
