🇸🇪Kullamannen by UTMB 100 mile:
Course Analysis & Race Readiness

171 km with only 1,767 m of gain, this course is defined by relentless flat mileage. Over half runs at 3% grade or less, making sustained forward progress the decisive challenge across a full ultra-distance day.

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 65% 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.

AerobicSustained engine

Foundational

Steady sustainable output over 171 km with 56% of terrain at 3% grade or less.

ClimbingVertical power

14%

Nine modest climbs; longest 4.2 km, biggest 149 m gain. No sustained ascents.

DescendingEccentric / braking

Seven descents including a 6.9 km stretch; managing repeated gentle downhill without quad fatigue.

DurabilityLate-race resilience

171 km with minimal recovery from grade changes; the flat profile compounds fatigue over hours.

Pillar Breakdown

Aerobic

With 56% of the course flat and a total gain of just 1,767 m, sustained aerobic output rather than climbing power drives pace. Efficient running economy over 171 km is central.

Climbing

100

Climbing demands are limited: nine climbs with the longest at 4.2 km and the biggest gaining only 149 m. Short efforts, no prolonged vertical grind.

Descending

Seven descents, the longest 6.9 km losing 136 m at the biggest, ask for controlled downhill running. Gentle grades still accumulate quad load over the distance.

Durability

The dominant demand: 171 km on largely flat terrain means constant muscular loading with little variation to spread fatigue. Holding form late is the defining test.

km 118–121

Biggest Climb at 149 m

The course's largest single ascent gains 149 m over 4.2 km at 5.3% grade past the 118 km mark, arriving when legs are already deep into the distance.

km 157–163

Late Descent-Climb Sequence

After 157 km, a 126 m descent flows straight into a 128 m climb, forcing a rhythm change deep in the race when durability is most tested.

Flat Mileage

The Relentless Runnable Terrain

With 56% of the 171 km at 3% grade or less, there is little terrain variation to break up the effort, making pacing discipline the central challenge.
