Set in Ushuaia, the southernmost city on Earth, this trail running event takes place on the archipelago of Tierra del Fuego each March. Runners tackle six loop courses ranging from 12.5 km to 113 km, crossing lenga forests, peat bogs, and glacial lagoons while enjoying panoramic views of the Beagle Channel. As part of the UTMB World Series since 2026, the event awards Running Stones and offers a challenging, high-altitude experience with unpredictable Patagonian weather.
