Non-standard fixed-time endurance event
Conventional metrics are not applicable.
The selected 2027 edition is a fixed-time format with no truthful fixed headline distance. Race For You records the verified objective, loop and event-window facts separately. Conventional Difficulty V2, Cutoff Pressure V2, cutoff pace and personal-finish calculations are unavailable because they would require fake inputs.
This format is intentionally not converted into a normal 50K, 100K or 100-mile comparison. Its event window is not relabelled as a conventional cutoff. Check the organiser before entering, travelling or using these details for training decisions. An older edition may appear in the archive, but its course facts are not silently carried into this one.

How the format works
A real objective, not a fake distance.
Accumulate distance for 24 hours; complete at least one 5K lap in every hour to remain in the event. Additional laps within each hour are allowed.
Source transparency
Verify the final event detail.
2027 is stored as a fixed-time 24-hour event on a 5K loop, not as a fixed-distance race or true backyard. Total distance and ascent remain result-dependent, so the conventional predictor is blocked. Field-scoped check 2026-09-28: The official 2027 page gives £75 for solo entry and Grasmere Sports Field as start and finish. The separate £50 per-person team price is not used for the solo listing. Only these facts were reviewed; other details retain their previous source dates.
