Article 2. Support provisioning


  • The "Great Trail Aneto-Posets", the "Tour of the Aneto" and the "Marathon of the Tucas" are disputed in semi-self-sufficiency (understood by this term that the number of supplies requires runners to carry their own food and drink for the sections between supplies).
  • There will be liquid and solid supplies at various control points.
  • The Organization will require that each participant transport the food they deem necessary for a semi-self-sufficiency test, with the number of numbers marked on the packaging.

  • A map with the itinerary, the mandatory control points of each route, the medical assistance posts and the points of possible return to Benasque will be delivered to all runners.
  • The Road Book will be provided with the most relevant aspects of each section of the routes and the track of each route for GPS on the website.


Article 4. Control Points (PC)


Participants, under their responsibility, must pass through the PCs and verify their passage through the timing system corresponding to each control. The PCs will be clearly visible and provided with voluntary staff of the organization. It is mandatory that all runners carry visible dorsal in the front when passing through the PCs so that the volunteers can take note of the passage of all the runners. All PCs are mandatory and not going through them implies disqualification. Participants are responsible for recording their passage through each PC either through the electronic system or by teaching and naming their number to volunteers based on each control. The runners who retire must notify the organization at any checkpoint or at the goal of their withdrawal.


Article 5. Security of proof

  • It is a high mountain race, which often runs off-road. They pass through snowfields, fields and rocky areas that may be slippery, in short, very technical areas that slow down the pace of the race, so you have to have a good technique to function in these areas.
  • There may be some section equipped with fixed ropes at the discretion of the Organization.
  • The orography of the terrain, weather conditions or any other circumstance can make an aerial and rapid evacuation impossible and, although there will be checkpoints and specialized personnel distributed along the route, it is possible that the withdrawal or rescue is painful and lasting. One more reason why the broker must have adequate personal material (see list of mandatory material).


Article 6. Security regulations


  • At dusk it is mandatory to turn on the front and the position lighting device (a red bicycle position light is used), which must be placed on the back of the backpack to be visible by the participants behind.

  • It is mandatory to help a participant who demands help.

  • Participants who leave at any of these points should indicate it to the person in charge of the control and will be taken to Benasque as soon as possible, prioritizing the needs of the transfers.
  • Those who leave must notify the Organization, either at a checkpoint or by contacting the Organization through the telephone number that will appear on the map and the number given to the runners.
