Existing saved event-to-place evidence reused; geography query derived from 'Prestatyn to Bangor'. GeoNames exact settlement/suburb name match for 'Prestatyn', country Wales, administrative area Denbighshire, region Wales; population 19085 (zero means unspecified). Representative event-area point, not a venue address, exact start or radius guarantee. Directional catalogue locations use the first disclosed event locality only as EVENT_AREA; other route endpoints are not substituted. Geographic lookup does not reverify dates or non-location facts.

Race For You difficulty
5.2/ 10
Hard
Moderate input evidence · 62% 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 0.35 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, coastal, road, mixed terrain.
trailcoastalroadmixed
Climbing density
24.4m per km
A more useful comparison than total ascent alone: it shows how consistently the course asks you to climb.
Cutoff analysis
Very high pressure
To finish inside 18h, the raw average required is 10:48 per kilometre (17:23 per mile), including every stop.
Raw pace10:48/km
PressureVery high 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.
Who this suits
First ultra?
There is not enough verified information to assess first-ultra suitability yet.
Exposure & kit
unknown kit
Significant overnight running is likely for many entrants. Lighting, temperature management and sleep strategy can materially affect the outcome.

Data PartialChecked 13 September 2026. Entry status: Unconfirmed. Current availability could not be established reliably from the official event and entry sources. The official page confirms 24 April 2027, 100km, 8,000ft, an 18-hour limit, six aid/feed stations and £99.50. Stale 'in 2025' wording does not create a different edition. Other stored facts retain their previous source review from 2026-09-02.
