About This Event
The KAT100 by UTMB delivers a quintessential Alpine trail running experience through the Kitzbühel Alps of Austria. Based in the charming village of Fieberbrunn, this event showcases some of the most scenic and challenging terrain in the European Alps, offering runners a journey across pristine alpine meadows, rugged mountain peaks, and traditional Austrian countryside. As part of the prestigious UTMB World Series, the event maintains the high standards expected from the global trail running community while celebrating the unique character of the Tyrolean landscape. The multi-day festival features five distinct distances, each designed to highlight different aspects of the region's mountain terrain, from accessible valley trails to demanding high-altitude traverses. The event's tagline, "Next Step To Heaven," reflects both the spiritual nature of mountain running and the literal elevation gained throughout the courses. With comprehensive spectator support, including cable car access to key viewing points and organized shuttle services, KAT100 creates a true mountain festival atmosphere that extends beyond the running community to embrace the broader Alpine culture.

The KAT100 by UTMB 24K runs through the Kitzbühel Alps in Austria's Tyrol region, based from the mountain village of Fieberbrunn. As part of the UTMB World Series, this race maintains the organization and course marking standards expected from the circuit while offering a distance that suits runners new to Alpine terrain. The August timing places the event in the heart of the Alpine summer season, when the high pastures are accessible and the mountain weather is most stable. The 24-kilometer distance fits between a long trail race and a short ultra, requiring more than quick legs but less than full ultra endurance. Runners moving up from road marathons or standard trail distances will find enough challenge to test their mountain skills without committing to 12-plus hours on course. The mixed terrain typical of the Kitzbühel Alps includes forest paths, alpine pastures, and rocky sections that demand attention to foot placement. Fieberbrunn sits in the PillerseeTal valley, a quieter alternative to nearby Kitzbühel that retains its working village character outside of ski season. The KAT100 weekend draws an international field through its UTMB affiliation, creating a focused trail running atmosphere without the overwhelming scale of larger circuit stops.

Runners navigate through classic Tyrolean landscapes, with the route likely featuring both sustained climbs and technical descents that require confident footing and mountain running experience. The August timing typically means dry, runnable conditions, though Alpine weather remains variable and runners should prepare for temperature fluctuations at higher elevations.

Runners cover 81 kilometers through the Kitzbühel Alps on terrain that varies from groomed mountain paths to technical alpine sections requiring careful navigation. The course profile and specific elevation gain remain unconfirmed, though the region's geography suggests significant vertical challenge. Extended sections above treeline expose runners to alpine weather conditions and require self-sufficiency between aid stations.
173K
The 173K route traverses the Kitzbühel Alps from Fieberbrunn, moving through a series of mountain passes and valleys that characterize this region of Tyrol. The terrain alternates between technical singletrack, wider alpine trails, and occasional jeep roads connecting high mountain huts. Sections of the course reach exposed ridgelines where runners encounter rocky, uneven surfaces requiring careful footing. The route shares many segments with the longer 200K course, providing a comprehensive tour of the region's geography. Runners pass through small mountain communities and alongside traditional alpine farming operations before returning to Fieberbrunn. The mixed terrain includes rooted forest trails at lower elevations and scree sections at higher points, with sustained transitions between altitude zones throughout the distance.
