Lore & Trivia
Catllaras 100K runs through the eastern Catalan Pyrenees — the same mountain range as Ultra Pirineu but in a less-visited, wilder section. The course crosses the Serra de Catllaràs and Cadí ranges through terrain that is technical, remote, and authentically Pyrenean. This is Catalan mountain running without the international gloss — smaller fields, fewer aid stations, and a closer connection to the pastoral mountain landscape that defines the Pyrenean borderlands.
- ▸ The course connects the Mediterranean Sea to the Maritime Alps in a single vertical journey.
- ▸ Medieval perched villages along the route have barely changed since the Middle Ages.
- ▸ The Maritime Alps are where the Alps meet the sea — nowhere else in Europe offers this coast-to-summit transition.
- ▸ Monaco and the French Riviera are visible from the mountain sections of the course.
- ▸ Established in 2015.
The Catalan Pyrenees at their most raw — no UTMB polish, just mountain, rock, and determination.
