Race For You difficulty
4.5/ 10
Moderate
Limited input evidence · 52% 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.

Data PartialThe live page verifies a western Saturday 50K plus eastern Sunday 50K. The factsheet has a stale date and conflicts on the eastern-stage ascent, so total and stage-two ascent remain unknown. Field-scoped check 2026-09-28: The official 2027 two-day route publishes approximately 1,200 m and 1,000 m stage ascent, totalling 2,200 m. Replace stale or unknown ascent provenance with the exact official source and field verification date supporting the revised elevation. Only these facts were reviewed; other details retain their previous source dates.
