Successful source check: 2 Sept 2026Source confidence: highChecked 13 September 2026. Entry status: Unconfirmed. Current availability could not be established reliably from the official event and entry sources. Official Rat Race material verifies 10 October 2026, the marketed 28-mile/45.06K route, approximately 1,646m ascent, £195 price, full marking and three aid stations. It is retained as an explicit below-50K threshold exception because the organiser markets it as an ultramarathon; a finish cutoff was not published and remains null. Other stored facts retain their previous source review from 2026-09-02.

Race For You difficulty
4/ 10
Moderate
Limited input evidence · 0% 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.
