Race For You difficulty
5.2/ 10
Hard
Limited input evidence · 26% evidence coverage
The main recorded demands are balanced overall demands. Course difficulty and cutoff pressure describe different challenges: more approachable terrain can still require a demanding pace to beat the deadline. Neither score assesses your personal fitness, safety or readiness.
Scoring details and version
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. Evidence coverage describes the recorded inputs, not prediction accuracy or your likelihood of finishing.
Weather, conditions and individual preparation can change the real difficulty significantly.

Trust the source, see the gaps.
Data PartialField-scoped verification 2026-10-20: Organiser confirms 8–12 October 2027 with named daily islands, separate marathon and half-marathon options, marked loops and £70 per day / £350 full week. Linked registration returned 403, so booking availability remains UNKNOWN. The five-half total is published as 106 km but also 76 miles, an inconsistent conversion; retain the explicit kilometre total with this conflict disclosed. No exact numeric single-day distance is inferred. Only the stated facts are confirmed for this edition.
