What This Race Demands

Four things this course asks of your body

Every course weights the four pillars of mountain-ultra fitness differently. Durability carries 42% of the scoring weight on this course — the terrain makes that the deciding factor.

Weighting shows where readiness is won or lost at this distance — not whether you need each pillar. An aerobic base is a given for a race this long, so it carries little deciding weight even though it's essential — the gaps open on the climbs, descents and the back half.

Pillar Breakdown

Aerobic

With 20% flat and 32% runnable climbing, the course rewards a durable aerobic engine that holds pace across the full 159km rather than raw top-end power.

Climbing

Seventeen climbs total 5,169m of gain, headlined by an 18.2km ascent worth 1,062m. Managing 14% of terrain above 10% grade demands efficient, patient climbing.

Descending

With 34% of the course pointed downhill and 5,164m of loss, descending is a primary load. Steep pitches near -15% and two 924m drops test braking control and quad resilience.

Durability

The single biggest demand: 17 matched climbs and descents totaling over 10,000m of vertical change accumulate fatigue that must be absorbed to the final kilometers.

KM 0–18

The Long Ascent

The course's biggest climb runs 18.2km and gains 1,062m. Pacing this early effort conservatively sets up the many climbs and descents still to come.

KM 95–103

The Big Drop

A sustained descent loses 924m over 7.8km at -11.8%. Landing this late-race plunge with intact quads is critical for the closing third.

KM 135–143

Late Descent Repeat

A second 924m loss at -11.8% arrives past 130km, demanding braking control from legs already carrying the accumulated fatigue of 5,000-plus meters of descent.

That was a sample
