KAT100 by UTMB – Endurance Trail
Kitzbühel → Fieberbrunn
Race guide
Updated 19 July 2026
The KAT100 by UTMB Endurance Trail is the 75 km option in the KAT100 by UTMB, run point-to-point from Kitzbühel to Fieberbrunn in the Austrian Tirol. Over its 74.7 km it climbs 3,896 m, reaching a high point of 1,995 m, and packs the concentrated mountain character of the longer KAT distances into a single big day. Starting at 765 m in Kitzbühel, the route heads straight for the high ground and then works its way across the Kitzbühel Alps through a rhythm of steep climbs and valley crossings before finishing in Fieberbrunn at 783 m. With a hard cut-off at Fieberbrunn of Saturday 18:00 and tight intermediate gates from the very first checkpoint, it rewards runners who climb efficiently and keep moving through the aid stations.
The Course: Kitzbühel to Fieberbrunn in 75 km
The Endurance Trail is a genuine point-to-point, leaving Kitzbühel at 765 m and covering 74.7 km with 3,896 m of ascent to Fieberbrunn at 783 m. The opening move is uncompromising: from the start you climb to Pengelstein at 1,911 m by 14.3 km, gaining well over 1,100 m in the first stretch of the race. From that high shoulder the course drops sharply to Jochberg at 933 m (31.3 km), the main low point of the day. From Jochberg the route rebuilds height to Jochberger Wildalm (1,427 m, 40.7 km), descends to Oberaurach (860 m, 50.1 km), then climbs again to Hochwildalm at 1,542 m (56 km) — the highest checkpoint on the course. A final rolling section crosses Lärchfilzhochalm (1,346 m, 67.3 km) before the closing descent into Fieberbrunn at 74.7 km. The result is a course that front-loads its biggest climb and never really lets the legs settle into flat running.
The Decisive Climbs and Descents
Everything about the Endurance Trail hinges on the first climb. The pull from Kitzbühel (765 m) to Pengelstein (1,911 m) is the largest single ascent of the race and it arrives immediately, before your body is warmed into the day. Attack it too hard and you arrive at Jochberg already emptied, with three more substantial climbs still ahead; hike it with control and you protect the whole back half. The second key sequence is the block from Jochberg to Hochwildalm. Between 31 and 56 km the course climbs to Jochberger Wildalm, drops to Oberaurach, then makes its highest ascent to 1,542 m at Hochwildalm — repeated 500–600 m climbs that grind down runners who over-spent early. The long descent off Pengelstein to Jochberg is also worth respecting: it is steep and comes early enough that trashing your quads there will cost you dearly on the Hochwildalm climb and the final drop into Fieberbrunn.
Pacing and Fueling It
The Endurance Trail's cut-offs tighten from the outset: Pengelstein at 14.3 km closes at Saturday 03:30, Jochberg at 31.3 km at 06:30, Oberaurach at 50.1 km at 11:00, and the Fieberbrunn finish at 18:00. Because the very first checkpoint already carries a cut-off, there is no easing into this race — you need to move purposefully from the start line and treat the early Pengelstein climb as fast, steady hiking rather than a stroll. Oberaurach at 50.1 km is the designated crew point, and it sits conveniently before the highest climb of the day to Hochwildalm. Plan to arrive there with a solid time buffer, refuel properly, and stock up for the two climbs that separate you from the finish. Between the aid stations the terrain is committing and the gaps meaningful, so carry enough calories and fluid to cover a full climb-and-descent cycle. Runners who keep eating on the long descents — when the stomach is calmest — tend to hold their pace best over the closing Lärchfilzhochalm section.
Conditions to Expect
Topping out at 1,995 m on Pengelstein and staying high on Hochwildalm, the Endurance Trail spends its hardest kilometres on exposed alpine terrain in the Kitzbühel Alps. Expect a real contrast between the warmer valley crossings at Jochberg and Oberaurach and the cooler, windier high shoulders, and pack a layer you can add for the tops even if the start in Kitzbühel feels mild. Depending on your pace, the early part of the race may be run in darkness given the Saturday 03:30 cut-off at Pengelstein, so a reliable headtorch and warm kit for the first big climb are essential. Weather in these mountains can shift quickly at altitude, so treat the summits of Pengelstein and Hochwildalm as the places most likely to be cold and wet. Steady climbing, disciplined layering and consistent fueling through Oberaurach are what carry runners to the Fieberbrunn finish inside the cut-off.
