Basajaun
#BASAJAUN2026
From the lush forests of Urbasa and Irati (home to Basajun), one descends to the most arid and barren plains through Bardenas, returning to the banks of the Ebro river before facing the Sierra de la Demanda, a mountainous massif in “land of cameros ”of transhumants who face very harsh lands in terms of climate, to culminate around the Pico San Lorenzo and return to the forests of the Basque Country, through the Izki Natural Park.
Meadows and lush beech trees make up this space on a 1,000m plateau that divides the Mediterranean climate from the Atlantic.
Despite the deforestation carried out during the Middle Ages for the construction of ships and later metal industry (manufacture of weapons) as well as the border struggles between Spain and France, Irati represents one of the largest forest masses of beech and fir trees in Europe
It represents a peculiar and unique environment in terms of geological and climatic composition, they constitute a semi-desert area with an added singularity, the ownership and administration of the lands between 22 “congozantes”, who have rights to exploit them.
A mountain range with a continental, arid climate, full of contrasts between reddish valleys of clay soil and large mountains of rock, crowned by Pico San Lorenzo (2270m).

Basajaun has a predetermined route from start to finish. If you decide to abandon it for any reason, you will have to pick it up later from the same point where you left off.
The official track will be sent to registered riders weeks before the start.
The accumulated unevenness is a matter to consider. After leaving Vitoria, the route enters Urbasa and then crosses the Navarrese Pyrenees and the Irati forest. After climbing again to more than 1,000m, the route continues through the desert of Las Bardenas and on the way back crosses the Sierra de la Demanda, passing near the San Lorenzo peak at more than 2,200m. The final stretch to Vitoria is again wooded and broken.
En cuanto al tiempo, prepárate para calor y el viento de Bardenas y la zona del Ebro temperaturas cercanas a 0C en La Sierra de Cameros.
If you prepare the route properly you will have no problem finding plenty of water and food. But remember, try to self-serve food for a day and refill the cans whenever you can.
It is forbidden to reserve any type of service before departure, which includes accommodation. Todo lo que tengas que necesitar durante la prueba deberá ser reservado una vez que esta comience y por cada participante de manera personal.
Family and friends are welcome to join Transiberica, but should only do so at the Start or Finish.
n route, family and friends will only be allowed access, with prior authorisation, by sending an email to info@transiberica.club with the place, runner and names of the applicants.

That time starts at the start and only for when you reach the finish line. While you are standing to rest, eat or sleep, time will continue to run, so good planning, strategy and knowledge about yourself is key to being a Finisher.
Ask people, find the route on your GPS or on your mobile phone … but don’t call home or any base camp: self-sufficiency consists of using your own means to solve your own problems.
Try to fix them yourself. If this is not possible, go to a mechanic using any possible means of transport and then return to exactly the same point where you left the route.
No, aunque algunos se lo tomarán como una carrera, es un reto personal, para muchos su reto será finalizar.
Although there will be a final classification based on the order of arrival, following the traditions of ultra-cycling and bikepacking, there will be no prize for the fastest rider except the honor of finishing first.
Your registration includes basic insurance covering Public Liability, Personal Accident, Emergency Rescue, Death, Repatriation, and basic medical assistance.
Coverage applies under normal participation conditions throughout the seven days of Basajaun. Insurance does not cover participants who are under the influence of alcohol or drugs.
In any case, it is advisable to read the terms and conditions of the insurance policy carefully, as well as to have a private insurance policy with more extensive medical coverage.
