Trail running at the end of the world, through subantarctic forests, glacial lakes, and windswept ridges above the Beagle Channel
The southernmost race in the UTMB World Series, held in Ushuaia at the tip of Argentine Patagonia. Six races from 12 to 130 kilometers cross subantarctic lenga forests, glacial lakes, and windswept ridgelines where the climate at 1,000 meters mirrors the Alps at 3,000, with the Beagle Channel and Antarctica beyond.
Held in Ushuaia, the southernmost city in the world, the Ushuaia by UTMB takes trail running to the very edge of the inhabited earth. Six races from 12 to 130 kilometers start and finish at Plaza Islas Malvinas and wind through the mountains of Tierra del Fuego, where subantarctic conditions at just 1,000 meters of elevation mirror those found in the Alps above 3,000. The flagship EPIC 130K covers 113 kilometers with 4,854 meters of climbing, starting in the predawn darkness and crossing multiple mountain passes through some of the wildest terrain in South America.
The courses traverse ancient lenga beech forests draped in moss, skirt crystalline glacial lakes like Laguna Esmeralda and Laguna Turquesa, and climb exposed ridgelines on Cerro del Medio, Cerro Cortez, and the iconic Five Brothers Mountain. Runners navigate peat bogs, ford rivers, and scramble over rocky terrain with panoramic views of the Beagle Channel, the waterway charted by Darwin in 1833. At this latitude, four seasons can unfold in a single day: sun, wind, snow, and rain arriving without warning.
Drawing 2,500 runners from over 50 countries, the event transforms Ushuaia each March into the trail running capital of the Southern Hemisphere. The raw, untamed beauty of Tierra del Fuego, the unpredictable weather, and the sheer remoteness of the setting create an experience that lives up to the race's Norse name: Valhöll, the mythic hall where only the bravest may enter.
