Race For You difficulty
3.6/ 10
Moderate
Moderate input evidence · 77% 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 0.00 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.

Course analysis
What shapes this race
Expect largely runnable, non-technical surfaces.
trailmixednon-technical
Climbing density
10.6m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
Low–moderate pressure
To finish inside 17h, the raw average required is 12:41 per kilometre (20:24 per mile), including every stop.
Raw pace12:41/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.
