Race For You difficulty

4.7/ 10

Moderate

High evidence confidence · 94% evidence coverage

This score is driven most by technical terrain. 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.

Weather, conditions and individual preparation can change the real difficulty significantly.

Course analysis

What shapes this race

Expect sustained upland ground and meaningful climbing, sections where foot placement and downhill confidence matter.

trailmountainfelltechnicalmixed

37m 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 21h, the raw average required is 15:34 per kilometre (25:03 per mile), including every stop.

15:34/km

Low–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.
