The Camille Extreme takes runners up and down 2,100 meters from Isaba, a village in Navarra in northern Spain. This June mountain race covers about 32 km, designed for solo trail runners seeking a challenging day rather than a relaxed countryside run.
The course crosses open meadow, beech forest, and limestone rock, with Peña Ezkaurre serving as the most demanding landmark. The race includes five aid stations, a six-hour time limit, and approximately 600 participants, giving it the character of a serious local mountain event. ADI-IKE organizes it, with the goal for the entire Camille Extreme weekend to feel like a communal gathering, extending beyond just the start and finish.
