Race For You difficulty
3.3/ 10
Beginner-friendly
High input evidence · 94% 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.

Course analysis
What shapes this race
Expect largely runnable, non-technical surfaces.
trailmixednon-technical
Climbing density
23m 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.
8.1/10 suitability
Navigation
fully marked
The route is described as marked, but runners should still read the final race instructions.
Exposure & kit
moderate kit
Night running is not expected for most entrants based on the current format, but final kit rules still take priority.

Data HighThe official 2027 page verifies the 12 June date, 50K distance, 1,150m vital-stat ascent, nine-hour cutoff, £85 affiliated fee, 400-runner field, four aid stations and marked course. Its route copy rounds the ascent to 4,000ft; the metric vital-stat value is retained. Field-scoped check 2026-10-20: 12 June 2027, 50 km, nine hours, Matterley Bowl to Queen Elizabeth Country Park and four aid stations remain confirmed. Registration accepts entries; £85 UKA / £87 general. Closure 30 May, time unspecified. Retain explicit 1,150 m table elevation; narrative 4,000 ft differs from table 3,800 ft and remains a disclosed conflict. Other facts retain their earlier field evidence.
