Conventional metrics are not applicable.
The selected 2026 edition is a backyard 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.
Complete one yard every hour; only the last runner to complete a solo yard finishes.
Source transparency
Verify the final event detail.
The cited 2026 edition sources were reviewed on 4 September 2026 and support the recorded date, cutoff state, format and lifecycle. Unresolved facts remain marked unknown rather than being inferred.
