What This Race Demands

Four things this course asks of your body

Every course weights the four pillars of mountain-ultra fitness differently. Descending 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.

Sustained output over 162km with only 16% flat terrain to recover on.

Pillar Breakdown

Aerobic

With 162km and roughly 33% of the course spent climbing, the engine must keep producing across a very long day with minimal flat recovery.

Climbing

100

Twenty-five climbs stacking 6350m, including a 551m biggest gain and a 6.8km longest ascent, plus 13.3% of distance at very steep grades, tax the climbing system repeatedly.

Descending

Descent is the dominant demand at 40% of the course, with 6399m of loss and a 9.7km, 827m descent that punishes quads and pounds the legs.

Durability

The steepest sections cluster past 138km, with a 330m climb, a 529m descent and a 304m climb late, so structural resilience over 100 miles is decisive.

km 144–148

Late 529m Plunge

A 3.85km descent dropping 529m at -13.7% arrives after 144km, hammering already-fatigued quads when control is hardest to maintain.

Longest descent

9.7km Downhill

The longest descent runs 9.7km and the biggest single loss is 827m, demanding braking economy and impact tolerance well before the finish.

km 138–153

Closing Climb-Descent Stack

After 138km the course throws a 330m climb, a 529m descent, then a 304m climb at 13%, forcing repeated hard efforts on worn legs.
