5.7/ 10
Hard
Limited evidence confidence · 42% evidence coverage
This score is driven most by balanced overall demands. 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.
Weather, conditions and individual preparation can change the real difficulty significantly.

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

Cutoff analysis
Very high pressure
Cutoff Pressure V2 is governed by the tightest published active-time stage: Pure 50K, with 9h for 50km. Its course-adjusted allowance is 8.49 minutes per effort-kilometre.
Governing stage pace10:48/km
PressureVery high pressure
The governing stage pace includes stops made during that stage. Between-stage recovery and sleep are excluded from active running allowance, so a broad multi-day event window cannot hide a tighter stage.
Because that stage's 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.
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.

No current compatible predictor target is available for this family. The selected edition may be complete or cancelled, awaiting a successor, non-standard, or missing model-critical course evidence; older facts are not substituted.
