Race For You difficulty
6.6/ 10
Hard
Limited input evidence · 48% evidence coverage
The main recorded demands are substantial race distance. 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 0.00 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. 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.

Cutoff analysis
Low–moderate pressure
To finish inside 40h, the raw average required is 14:55 per kilometre (24:00 per mile), including every stop.
Raw pace14:55/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.
Who this suits
First ultra?
There is not enough verified information to assess first-ultra suitability yet.
Navigation
fully marked
The route is described as marked, but runners should still read the final race instructions.
Exposure & kit
unknown kit
Significant overnight running is likely for many entrants. Lighting, temperature management and sleep strategy can materially affect the outcome.
Personal race predictor
Prediction unavailable
No current compatible predictor target is available for this family. The selected edition may be complete or cancelled, awaiting a successor, non-standard, or missing model-critical course evidence; older facts are not substituted.
