Top Dolomites Trail Run 2026

The new 61 km Ultra 3Tre route is an extraordinary journey into the heart of the Brenta Dolomites, combining breathtaking landscapes and epic challenges in a single experience. The first 33 km follow the route of the Ultra Trail 50 km, starting from the center of Pinzolo and reaching Fortini (1700 m altitude) at the foot of the Grostè chairlift. This is where the real novelty begins: the new section that has never been tackled by any ultra trail race! A challenge designed for those who want to push themselves further, for those seeking the essence of high-altitude trail running. The section retraces the legendary 3Tre slope, the historic protagonist of the Alpine Ski World Cup, in reverse. It will be like climbing a legend. 600 meters of elevation gain condensed into a vertical wall of pure sky running, with gradients reaching and exceeding 28%. A short but intense section, 400 vertical meters where every step will be a conquest. Once we reach the summit, we will skirt Lake Ritorto, a mirror of water nestled in the Dolomites. Then, we will descend towards Malga Ritorto, on a trail that will reconnect you, after just over a kilometer, with the 50 km Ultra Trail route. From here, there will be 10 km to go to the finish line, in the heart of Pinzolo, where the warmth of the crowd and the satisfaction of having achieved a new feat in the Brenta Dolomites will await you.
