Successful source check: 2 Sept 2026Source confidence: highThe official site verifies the completed 7 March 2026 50K, intermediate controls at North Berwick RNLI after 3.5 hours and Balgone after 4.5 hours, plus the six-hour Smeaton cutoff. Its 2023 organiser brief is retained only as historical route-character evidence; these edition facts are not copied into the separately confirmed 2027 listing.

Race For You difficulty
3.8/ 10
Moderate
Limited evidence confidence · 15% 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-affiliated Scurry Events page confirms 6 March 2027 and says entries are going live soon. The canonical JMWU page still foregrounds 2026, so only the edition date and 50K identity are verified. Edition format, ascent, cutoff, navigation and support remain unknown; any family-level route description is historical typical context, not a copied 2027 fact.
