Successful source check: 3 Sept 2026Source confidence: mediumChecked 13 September 2026. Entry status: Unconfirmed. Current availability could not be established reliably from the official event and entry sources. Finish: Jim's Gym, 20c South Gate, Sleaford NG34 7RZ. Starts 07:00 at 20c South Gate, Sleaford NG34 7RZ. Standard fee £80 plus £2 booking fee; gym-member fee £75. The strictly enforced 23:59 finish cutoff establishes an exact elapsed limit of 16 hours 59 minutes.

Race For You difficulty
4.7/ 10
Moderate
Limited input evidence · 30% 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 0.15 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.

Course analysis
What shapes this race
The course combines trail, road, mixed terrain.

Cutoff analysis
Moderate pressure
To finish inside 16h 59m, the raw average required is 12:40 per kilometre (20:23 per mile), including every stop.
Raw pace12:40/km
PressureModerate pressure
Cutoff pressure compares the published time limit with distance, ascent and verified course demands. Lower pressure does not mean the race is easy. Raw pace includes checkpoints, food stops, navigation errors and any sleep; it is not a pacing plan.
Because ascent is not verified, Cutoff Pressure V2 uses the model's neutral 20m/km reference density. This assumption does not fill the ascent value or make missing evidence look easy.
