🇦🇹Grossglockner Ultra-Trail 110 km:
Course Analysis & Race Readiness

107 km with 6285 m of climbing and 6283 m of loss across 18 climbs and 13 descents. Nearly half the course points downhill, demanding legs that can absorb punishment for over a hundred kilometers.

CourseRecon scores your own training against the descending and durability demands that define Grossglockner Ultra-Trail 110 km — the sample analysis below shows exactly how.

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 49% 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

Covering 107 km with 6285 m of gain requires steady aerobic economy across a 1884 m elevation span. The distance keeps the aerobic engine working continuously from start to finish.

Climbing

Eighteen climbs totaling 6285 m demand strong uphill power, with a 12.4 km climb, a 1183 m ascent, and a 766 m pitch averaging 18.2%. Very steep climbing spans 20 km of the course.

Descending

With 6283 m of loss and descent making up 45% of the course, this is the decisive capacity. A 1508 m biggest descent and a 507 m plunge at -23.4% demand eccentric strength and control.

Durability

Alternating 18 climbs and 13 descents over 107 km batters the legs progressively. Late climbs like the 654 m ascent at km 93 test whether power survives past 90 km.

km 66.9–69.0

The -23.4% Plunge

A 507 m drop at -23.4% over just 2.2 km is the steepest section on course. Legs already loaded from earlier descents must absorb brutal eccentric force here.

km 49.9–54.1

The 766 m Wall

A 766 m climb averaging 18.2% over 4.2 km sits near the midpoint. Sustained very-steep effort tests uphill power before the descending demands intensify.

km 93.0–96.7

Late 654 m Climb

A 654 m ascent at 17.4% arrives past 90 km, exposing whether climbing strength endures after 6000 m of accumulated gain and loss.
