Race For You difficulty
5.3/ 10
Hard
High input evidence · 94% evidence coverage
The main recorded demands are technical terrain. 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 sections where foot placement and downhill confidence matter, forest trail that may change character in wet conditions.
trailforesttechnical
Climbing density
37.7m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
Very high pressure
To finish inside 15h, the raw average required is 11:07 per kilometre (17:53 per mile), including every stop.
Raw pace11:07/km
PressureVery high 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?
This is not designed as a first-ultra recommendation. Significant endurance, navigation or mountain-race experience is strongly advised.
2.8/10 suitability
Navigation
fully marked
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.
