Race For You difficulty

4.7/ 10

Moderate

Moderate evidence confidence · 78% evidence coverage

This score is driven most by balanced overall demands. 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.
