Osttirol Trail | OTT 84 km, 5,000 altitude metres, 4 ITRA points

Through the most beautiful parts of the Glockner Group

The Osttirol Trail (OTT) starts at Enzingerboden (1,483 m) at the lower terminus of the cable car to the Weißsee Glacier World. From there, via the intermediate terminus of the cable car directly to the Berghotel Rudolfshütte (2,315 m). Then it continues to the Kalser Tauern (2,515 m), ending across a snowfield. Then a long, technically difficult descent to Dorfertal, approx. from Kalser Tauernhaus flat and later slightly downhill to Kals am Großglockner (bandstand). From Kals, a long climb to the idyllic ‘Greiwiesen’ and a short descent to Lucknerhaus with a magnificent view of the Grossglockner.

From there, an ascent through beautiful flower meadows to the highest point of the route and supply station at the Glorer Hütte (2,642 m). From the Glorer Hütte, enjoy slightly downhill trails and a short uphill climb to the Salmhütte and on to the Stockerscharte (2,465 m) with magnificent views of the Pasterze. From the Stockerscharte, a technically demanding descent over the Margaritze reservoir dam, uphill via the Glocknerhaus, and finally over a snowfield to Untere Pfandlscharte (2,663 m).

A final look back to the Grossglockner, then across another snowfield (caution!), continuing on a long descent to the Trauneralm. Flat from there to Ferleiten and then slightly downhill on trails to Fusch an der Glocknerstrasse.

From Fusch, take the final ascent, then descend to the centre of Kaprun with the finish line at Salzburger Platz. The route passes 9 glaciers and around 300 peaks of over 3,000 m.

OTT is a very demanding route with mostly high-altitude trail running. This is not only due to the total altitude metres, 3 passes over 2,500 m, but also to the technical difficulty. The high average altitude over more than two-thirds of the route poses an additional challenge. Racing experience over comparable distances, preferably in the mountains, sure-footedness and experience in alpine terrain are prerequisites. See below for the nature of the race and requirements; please also note the ‘minimum equipment’ list.

Nature of the race

The Osttirol Trail (OTT) is an extreme running event, mostly in high alpine terrain with 1 passage above 2,800 m and 2 passages above 2,500 m and 2,600 m respectively. At least 3 snowfields must be crossed, and more in poor conditions. Over long stretches (90%), the route leads over trails that are (sometimes very) technically demanding. Poor weather conditions (cold, rain, snow) and nighttime add to the difficulty.

The trails are technically difficult to run throughout. The most difficult are the ascents/descents to the high passes: Kalser Tauern (2,515 m), Stockerscharte (2,465 m) and Untere Pfandlscharte (2,663 m).

Requirements

All participants must be physically fit and sure-footed in order to complete the course in accordance with the rules. Experience in longer endurance events, preferably in the mountains, but in any case combined with experience and confidence in moving in high alpine terrain, are essential prerequisites for participation. The minimum age for participation is 18 years.
