Race For You difficulty
4.3/ 10
Moderate
Limited evidence confidence · 42% evidence coverage
This score is driven most by balanced overall demands. 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 long runnable canal sections where pace discipline matters more than technical skill, largely runnable, non-technical surfaces.

Cutoff analysis
Low–moderate pressure
To finish inside 15h, the raw average required is 13:59 per kilometre (22:30 per mile), including every stop.
Raw pace13:59/km
PressureLow–moderate 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.
Because ascent is not verified, Cutoff Pressure V2 uses the model's neutral 20m/km reference density. This assumption does not fill the ascent value or make missing evidence look easy.

There is not enough verified information to assess first-ultra suitability yet.
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 exposure has not been verified for this edition. Check the organiser’s latest schedule, route information and final kit rules.

Data PartialThe page body and refund schedule explicitly support 24 April 2027, 40 miles, a 15-hour limit and £45, while its heading still says MBCR 2026. The current body is used with Medium confidence and the stale heading is retained as a source conflict; the 2026 manual is not copied into 2027.
