The Salomon Ultra Pirineu 100K is a 100.2km loop with around 6,550m of elevation gain through the Cadí-Moixeró massif, starting and finishing in Bagà, Catalonia. The overall cutoff is 26 hours 30 minutes, and the highest point is Niu de l'Àliga at 2,520m. Winning times are typically around 10–11 hours.
The race opens with a hard climb to Niu de l'Àliga and stays mountainous throughout. External assistance is limited to Niu de l'Àliga, Serrat de les Esposes, Gósol, and Estasen; drop bags go to Gósol only. Early October weather in the Catalan Pyrenees can swing from warm valley starts to cold wind on the ridges - pack layers for both.
