Successful source check: 2 Sept 2026Source confidence: mediumThe exact official result record confirms an Ultra Marathon running on 19 January 2025. The official archived route page identifies that Ultra product as 32 miles/51.5km, while the current organiser page says the extension to 55.5km began in 2026; the continuity inference is therefore medium-confidence. Ascent, cutoff and price remain unknown.

Race For You difficulty
4.2/ 10
Moderate
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.
