Lore & Trivia
Ronda dels Cims is Andorra's ultra — a 170km route that touches every major summit in the tiny Pyrenean principality, accumulating a staggering 13,500m of elevation gain. For context, that's 170km with the vertical equivalent of climbing from sea level to the top of Everest and continuing to 2,000m above. Andorra is 100% mountain — the entire 468 km² country sits between 840m and 2,942m — and Ronda dels Cims makes you climb all of it. The race crosses the French and Spanish borders multiple times, visits remote mountain refuges, and traverses terrain that alternates between pastoral valley bottoms and exposed high-altitude ridgelines.
