Race For You difficulty
4.4/ 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 0.15 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 forest trail that may change character in wet conditions, long runnable canal sections where pace discipline matters more than technical skill.

Cutoff analysis
Moderate pressure
To finish inside 14h, the raw average required is 12:08 per kilometre (19:32 per mile), including every stop.
Raw pace12:08/km
PressureModerate 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.
