What Makes It Great

A grueling 105-kilometer loop through the Principality of Andorra, summiting the country's highest peak — Pico del Comapedrosa (2,942m) — and traversing remote high-altitude Pyrenean ridgelines, glacial lakes, and traditional mountain refuges. With 6,900 meters of elevation gain, a 34-hour cutoff, and night running through the mountains, the Ultra 105K takes runners on a complete circuit of one of Europe's smallest but most mountainous nations.
