An iconic mountain challenge in the heart of the Brenta Dolomites.
Wild forests, exposed ridgelines and high-altitude trails frame a raw and unforgettable journey through Madonna di Campiglio, Grostè, Pinzolo and Lake Ritorto.

Four distances — Short Trail 10 km, Medium Trail 22 km, Ultra Trail 50 km and the new 61 km Ultra 3Tre — welcome every kind of trail runner, from passionate newcomers to seasoned ultra athletes.
The 2026 highlight is the Ultra 3Tre: a legendary climb up the historic World Cup ski slope, tackled in reverse — short, steep and relentlessly epic.

Technical terrain, breathtaking scenery and an electrifying festival finish in Pinzolo turn every finish line into a celebration of pure trail running.

Run a legend. BECOME A TOP!
