Grossglockner Ultra-Trail aid stations and cutoffs

You start at 9:30 on Friday night in the centre of Kaprun. In 2026 the route went through the lit-up Sigmund Thun Gorge for the first time, then climbed to the Mooserboden reservoir, crossed the dam and went over a snowfield to the Kapruner Törl (2,639 m). From the Rudolfshütte another snowfield takes you to the Kalser Tauern and a long, technical descent into the Dorfertal and down to Kals, which has your drop bag, a hot meal and a rest area.

From Kals you climb to the Glorer Hütte (2,642 m), go on past the Salmhütte to the Stockerscharte, then down over the Margaritze dam and up past the Glocknerhaus to the Untere Pfandlscharte (2,663 m). Lucknerhaus and the Pfandlscharte are time checks only, with no food on the 2026 profile. After the Pfandlscharte it's 19.3 km to Fusch with only drinks at Ferleiten, and then 15.1 km with one last climb back to Kaprun. The organizer recommends several races over 70 km before you enter. The stops and cutoffs are the 2026 ones.

The OTT starts at 4:30 on Saturday morning at Enzingerboden (1,483 m), at the bottom of the Weißsee Glacier World cable car, and climbs straight to the Rudolfshütte. From there it is the GGUT course: the snowfield to the Kalser Tauern, the long descent of the Dorfertal to Kals, then the Glorer Hütte, the Stockerscharte and the Untere Pfandlscharte before the run down through Ferleiten and Fusch.

You cross at least three snowfields, and the organizer reckons about 90% of the trail is technical. More than two thirds of it is high up. Kals has the drop bag and a hot meal. The kilometers here are read off the 2026 altitude profile, whose axis ends at 83 km; the race page gives 84.

The GGT starts at the bandstand in Kals at 7:30 on Saturday and follows the old Glocknerstrasse up to the Lucknerhaus. From there it climbs through flower meadows to the Glorer Hütte, past the Salmhütte and the Stockerscharte, with views of the Pasterze glacier. A technical descent takes you over the Margaritze dam, then you climb past the Glocknerhaus and over a snowfield to the Untere Pfandlscharte.

The organizer calls it the most runnable of its races, but it's still 3,500 m up and 4,000 m down with at least two snowfields. The second half is long: on the 2026 profile, after the Pfandlscharte there's only a drinks station at Ferleiten before Fusch, and a final climb before Kaprun.

The GWT leaves Enzingerboden at 8 on Friday morning, passes the Grünsee and climbs to the Rudolfshütte, which has only drinks on the 2026 profile. The organizer counts the next stretch among the hardest: down to the Tauernmoos reservoir, then up through the Rifflkar past the Rifflsee to the Kapruner Törl (2,639 m), the high point and a time check. You come off it on a snowfield, run along the Mooserboden reservoir with a view of the Wiesbachhorn and cross the dam to the one full aid station.

The descent below the reservoirs is technical in parts as far as the Kaprun Gletscherbahn. From there it's flat into Kaprun. You need to be 16 or older.

The KST starts at Salzburger Platz at 8:30 on Friday and follows cycle paths for about 2 km before climbing over the Bürgkogel and circling the Klammsee. From there you climb about 1,000 m via the Schneckenreitalm and the steep Jetzbachastensteig to the Alpengasthof Glocknerblick, the aid station on the 2026 profile, with views of Kaprun, Zell am See, the Großes Wiesbachhorn and the Grossglockner.

About 90% of it is on well kept hiking trails, so the organizer rates it not particularly difficult technically, and the descent comes straight back to Kaprun. The limit is 3 hours 30 minutes. It came back in 2026 after two years off and sold out.
