Großglockner Ultra-Trail: Course, Elevation & Route Profile

Course & Elevation

The gun goes on Salzburger Platz in Kaprun at 769 m, in the dark. A few valley kilometres later the first sustained climb starts at km 6: 6.2 km averaging 12.7 per cent, past the Kaprun glacier lifts up to the Mooserboden reservoir. At km 21 comes the short brutal ramp to the Kapruner Törl at 2,639 m: three kilometres at 19.4 per cent with pitches near 38 per cent, run entirely by headtorch.

Past the Tauernmoos reservoir, the Rudolfshütte at 2,315 m and the Kalser Tauern the course drops into the Dorfertal, passes the Kalser Tauernhaus and reaches Kals am Großglockner, the low point of the second half. The hardest block begins there: two climbs at km 51 and km 57, 4.2 and 4.3 km long at 18.2 and 17.1 per cent, running past the Lucknerhaus to the Glorer Hütte at 2,642 m. Salmhütte, Stockerscharte, the Margaritze reservoir and the Glocknerhaus follow before the loop tops out at km 74 on the Untere Pfandlscharte, 2,663 m.

All of this sits inside the Hohe Tauern National Park, largely on technically demanding mountain paths, and several snowfields have to be crossed even in high summer; the mandatory kit of shell, warm layer and headtorch is not a formality. After the Pfandlscharte the route falls away over the Trauneralm and Ferleiten to Fusch an der Glocknerstraße at around 830 m, and then, at km 95.5, one more climb of 3.4 km at 18.9 per cent stands between you and the run-in to Salzburger Platz.

Pacing Strategy

Almost 57 per cent of the loop is steep ground and only 8 per cent is flat, so there is no race pace here in the usual sense. What matters is how economically you hike: the first 25 km up to the Kapruner Törl are a night climb on fresh legs, and that is exactly where most starters spend the reserves they will need twelve hours later.

The race is decided between Kals and the Glorer Hütte. Two climbs totalling roughly 1,500 m of gain arrive after a night without sleep and usually in the midday heat; whoever can still climb evenly there finishes in a different bracket from someone who forced the pace back at the Kalser Tauern.

The second trap is the descending. More than 6,300 m of it, including the long plunge from the Pfandlscharte down to Fusch, costs more substance than the climbs do, and the final climb at km 95.5 forgives nothing once the quads are gone. Brake deliberately on the early descents; time won there is lost twice over in the last quarter.

Training plan for Großglockner Ultra-Trail: 12-week build

Plan for 20 to 28 hours out there as an age-group runner. The demand is almost entirely aerobic and hiking-led: long climbs at a march, technical descents in between that ask for concentration rather than speed. Training therefore targets duration and fatigue resistance, not threshold power. Weekly volume matters less here than a handful of genuinely long sessions and the ability to repeat them over months.

The decisive phases come late. The double ramp to the Glorer Hütte after 50 km and the 649 m climb at km 95.5 both require you to still climb steeply after many hours on the move. Simulate that with back-to-back weekends: a long mountain day, then several hundred metres of gain on tired legs the next morning, consistently with poles.

Conditions are their own training content. A night start, many hours above 2,400 m, snowfield crossings and a late-July weather window that can deliver valley heat and wet snow on a pass on the same day. Night runs with your own headtorch, time at altitude beforehand and a fully tested pack with the complete mandatory kit belong in the final weeks.

Three emphases remain: eccentric durability for more than 6,300 m of descending, sure footing on rough alpine path, and a fuelling plan that holds through a full day and a full night. A stomach you do not sort out in training will not sort itself out in the race. Practise eating while hiking a steep climb, because that is where most of the calm minutes of this race are.
