The excursion will start in Tolosa, and after passing through the summits of Uzturre and Erroizpe, the runners will return to Tolosa. The route is approximately 24 kilometers long with a positive elevation gain of about 1,600 meters.

Although the route is demanding, participants will adapt to the group's pace and dynamics, offering an opportunity to explore the surroundings and enjoy the company of fellow participants. As it will be a long outing, it is recommended that everyone bring their own water and food. The organizers also advise bringing a change of clothes and, especially, suitable footwear.

Participants will travel by car to the starting point, which is Tolosa. They will gather at 07:15 AM at the skate park, in the parking lot located opposite GKN and the football field. A WhatsApp group will be created with the registered participants to coordinate carpooling.

Registration will be done through the Inda Mendi M.B. website. For any questions or further information, interested individuals can contact via WhatsApp at the phone number 666 377 442.
