Race For You difficulty
4.5/ 10
Moderate
Limited input evidence · 10% 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 0.35 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.

What shapes this race

Cutoff analysis
Very high pressure
To finish inside 8h, the raw average required is 9:56 per kilometre (16:00 per mile), including every stop.
Raw pace9:56/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.
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.
