Lore & Trivia
The Innsbruck Alpine Trailrun Festival has positioned Austria's Olympic city as the trail running capital of the eastern Alps. The Nordkette ridge rising directly above the city centre provides the course's defining feature: a climb from 570m to over 2,300m in just a few kilometres, with the entire city visible below. Innsbruck's combination of world-class mountain terrain and efficient Austrian logistics makes it one of Europe's best trail running destinations.
- ▸ Innsbruck is surrounded by mountains on all sides, making it one of the most dramatic city starts for an ultra.
- ▸ The Nordkette ridgeline section is genuinely exposed with steep drop-offs on both sides.
- ▸ The race showcases three distinct mountain ranges in a single loop — Nordkette, Karwendel, and Stubai.
- ▸ Innsbruck has hosted two Winter Olympics, and the trail running festival has become another major sporting event for the city.
- ▸ Established in 2016.
Innsbruck sits in the Inn Valley with mountains rising 2,000m on both sides. The course exploits every metre of that vertical.
