Racing in the KAT100 – trail running in the Pillersee Valley

Running Collection by PillerseeTal - Kitzbüheler Alpen

Your heart's racing. Sweat drips from your forehead. Breathing is difficult. With every step across the scree, your calves burn. Higher and higher, further and further. Just a few metres to the summit. Don't give up now! You look briefly down into the valley and clench your teeth once more. One foot in front of the other, you run up the mountain, passing relaxed hikers, your trail running sticks firmly in your grip. There's the summit cross! A rush of emotions overwhelms you at the sight of the gigantic mountain panorama. You rest your hands on your knees for a moment and your pulse slows down. "This is where I ran up?" Proudly your view wanders over the landscape. Clouds move slowly through the valleys, over green hills and sunlit peaks. Up here, you are very close to nature. Soon, you head downhill – fast. You take a sip from your water bladder and get going. The challenge has just begun – welcome to the KAT100, the longest Ultratrail in Austria!

The town of Fieberbrunn in the heart of the Kitzbühel Alps hosts the ultimate trail run, KAT100. The race combines running and nature to show you the most beautiful and challenging peaks and grassy mountains in the Pillersee Valley. You can test your limits on six routes of varying distance – from the smooth 5-mile (8-km) Easy Trail to the 54-mile (87-km) Enduro Trail to the monster KAT100 Miles (160-km) route which has almost 33,000 feet (10,000 m) of ascent. The Speed Trail, Marathon Trail or Ekiden Relay Trail are great intermediate distance routes. No matter which route you choose, beautiful nature is guaranteed.

To prepare you for this unique challenge, we have prepared five varied trails in the grassy mountains of the Kitzbühel Alps. Each trail is different so you can choose whether to take it easy on the original KAT100 Easy Trail competition course or to push your limits as an experienced trail runner on the Speed Trail. We’ve also included three demanding training loops: the Alpine roller coaster which takes you over numerous peaks, the downhill paradise route and the Panorama Challenge which includes the world’s largest accessible summit cross.

The Pillersee Valley region serves as an ideal basecamp. You can choose from a wide range of accommodation such as affordable guesthouses, rustic farms, or luxury hotels. If you aren’t quite ready for trail running in the mountains just yet, you can discover some wonderful hikes in the region too (

    This round is a nice start to trail running in the PillerseeTal in the middle of the Kitzbüheler Alpen - a crisp trail with moderate elevation gain. The route also corresponds to the original competition route of the KAT100 Easy Trail.From the pretty center of Fieberbrunn, you first walk on asphalt roads to the idyllic Lauchsee and continue uphill to the last farm. There the route branches sharply down to the right. The path leads through the fragrant forest and over wonderful meadows into the Pletzergraben. Along the babbling brook, it goes out of the valley for you. Before the main road, turn right at the Gasthof Auwirt and walk back over Reitlliftweg, Grasl, the social center and the Pavillonweg to the center of Fieberbrunn, where you started your round.

    A summit is not a summit - that's why you take three of them with you on this absolutely demanding trail.From the center of Fieberbrunn, the route initially runs leisurely on gravel paths through the Pletzergraben towards Herrgottbrücke. Here you turn into the right path and walk steadily upwards towards Lachtalgrundalm, Schlinachalm and Lengfilzenalm towards Gaisberg (1,798 meters) and Gebrajoch (1,779 meters). Surefootedness is required for the next section of the route! Once to the top of the Gebras (2,057 meters) and back.You continue on the Fieberbrunner Höhenweg with a beautiful panorama towards Niederer Mahdstein and Jufenhöhe before the next striking ascents and descents await you. Up to the Wildseeloder (2,118 meters), down to the Wildseelodersee (1,854 meters) and up to the Henne (2,077 meters). From here it goes downhill! Via Reckmoos towards Grießenbodenalm and Lärchfilzhochalm, over the Grutten to the valley station of the Fieberbrunn mountain railways and over the main road (underpass near Walchau) back to the center of Fieberbrunn.

    From zero to a hundred! To run in, you start comfortably from Fieberbrunn towards Hochfilzen, before your pulse rises on the Buchensteinwand on the very direct climb. No mercy on the downhill trail back to the center of Fieberbrunn!From the center of Fieberbrunn you walk the first four and a half kilometers on asphalt roads up to the Gasthof Eiserne Hand. There you turn sharply left, follow the road uphill before turning left at the next intersection towards Rotache. Through the underpass you reach the hamlet of Pfaffenschwendt. Here you again use the railway underpass and run onto the gravel road of the Buchensteinwand circular route. Slightly rising, this leads you to Hochfilzen-Warming.Things really get going from kilometer nine! The coming 500 meters of altitude run very directly on the plateau of the Buchensteinwand, where the 30-meter-high walk-in Jakobskreuz sits enthroned. Once here, you can take a short break and - if you like - climb the Jakobskreuz. The rapid path back to the center of Fieberbrunn takes you over the Tennalm and the hamlets of Pertrach and Schönau.

    A speed distance with some ups and downs. Crunchy climbs are followed by no less demanding downhill passages.From the center of Fieberbrunn you first walk west along the Achen promenade to the fork in the path after the soccer field. Here on the right over the bridge, then you cross the main road and keep briefly to the right. At the Gasthof Obermair the route leads up to the left on asphalt, under the railway line, in the direction of Obwall At the fork in the road, continue straight towards Tennhäusl. From there you run on beautiful trails towards Gerstberg and Lehrbergalm. Here follows the first downhill passage down towards the hamlet of Lehrberg. You cross the state road, walk right at the Hotel Kitzspitz and left at the next Stadl.From now on it's uphill! The crisp climb to the Buchensteinwand with the 30 meter high Jakobskreuz over about 600 and more meters will get your pulse going. The view from the summit is beautiful, from the Jakobskreuz great! But this is where the second downhill passage begins for you. First down towards Tennalm, but halfway you turn left towards Fieberbrunn-Buchau. In Buchau keep to the left and follow the Buchensteinwand circular route towards the hamlets of Pertrach and Schönau back to the center of Fieberbrunn.
