3.8/ 10
Moderate
Moderate evidence confidence · 74% 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.

Latest verification
Trust the source, see the gaps.
Data PartialOfficial event, options and factsheet pages verify the new 28–29 August 2027 event, active registration, continuous 84K option and £199 self-funded standard fee; alternative fundraising commitments are not treated as comparable entry prices. Their approximate ascent estimates differ by 50m. Ultra March and Trailblazer times are category goals rather than a universal cutoff, and the separately sold 42K plus 42K staged option is not merged.
