Race For You difficulty
3.5/ 10
Moderate
Moderate evidence confidence · 67% 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.

Data PartialThe organiser confirms 5 June 2027, 31 miles, 3,500ft, £63 affiliated/£65 standard and three water stations. Its enter-now CTA still targets the closed 2026 portal, so registration is unknown and the 2026 field cap is not inherited. No numeric final cutoff or navigation classification is published.
