Race For You difficulty
9.1/ 10
Extreme
Moderate evidence confidence · 74% evidence coverage
This score is driven most by substantial race distance, high climbing demand, accumulated fatigue and format burden. 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.
Weather, conditions and individual preparation can change the real difficulty significantly.

Course analysis
What shapes this race
Expect sustained upland ground and meaningful climbing.

Climbing density
28.4m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
Lower pressure
To finish inside 120h, the raw average required is 22:22 per kilometre (36:00 per mile), including every stop.
Raw pace22:22/km
PressureLower 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.

Latest verification
Trust the source, see the gaps.
Data PartialThe current official product page verifies 14–19 April 2027, 200 miles, approximately 30,000ft, a strict 120-hour overall cutoff, eight staffed aid stations, three optional sleep stations and crew support. The linked current registration page verifies open entry at £549. Conflicting ascent figures remain structured rather than silently blended; 2026 checkpoint timings are not copied into 2027.
