El Paso Austral- Ultra Trail is a non-stop trail race featuring 100% of the course on dirt trails. This trail running event is held within  both the Nahuel Huapi National Park (Argentina) and the Pérez Rosales National Park (Chile), traversing across the Andes at the  mythical “Vuriloche Pass”. The course parallels the journey that the local indigenous people used for trade back in the 1200s.  Spanish explorers and Jesuit missionaries looking for the fabled “City of the Caesars” also used this trail in search of a pass near the  Nahuel Huapi region.  

El Paso Austral – Ultra Trail goes over a wide variety of geographic features that are rarely seen in a single course such as ancient  glaciers, the majestic Cerro Tronador (3,491m.a.s.l.), lakes, rivers, creeks, hot springs, mountain huts, rocky slopes, areas with long  established landowners, the international border pass, wild marshes, forests, the Valdivian rainforest, and an amazing view of the  Pacific Ocean upon reaching the finish line.

  • Runner’s personal bag (Only 120K distance): The race kit for 120K runners will include a numbered personal bag that  runners may use for their belongings (replacement clothes or food). They may have access to this bag at the Pampa Linda  checkpoint (located at km 52 of the course). All runners must deliver this bag on check-in day to guarantee that it will be  transported to the Checkpoint (PC). When the race is over, runners may pick-up their bag at the office of the race  organizers with their race bib. In the event the runner withdraws from the race at the Pampa Linda checkpoint, he/she can  pick-up his/her personal bag at that location.

At check-in, the travel bag will be delivered to and  inspected by a Customs officer, who will place a seal on the bag that can only be removed by the runner at the finish  location. 

IMPORTANT: In case of withdrawal from the race, the runner should be aware the bags will be available when the race is over and  the Organizers return to Bariloche on Sunday (sometime during the day). 

4.6 – Mandatory equipment 

For their own safety and for the successful outcome of the race, all runners must have all the mandatory items listed on the official  website (https://elpasoaustral.com/equipo-obligatorio).

All runners must submit their mandatory equipment for verification both at the check-in as well as randomly at any checkpoints  along the course. Failure to comply with this requirement constitutes grounds for disqualification. 

Team members must submit their equipment individually. Only the first aid kit can be shared. 

4.7 – Insurance 

It is mandatory for 70K and 120K runners to have individual medical insurance with international coverage. Insurance information must be provided at check-in. The event Organizers will also carry their own insurance and will provide medical assistance and  rescue services along the entire course. 

Note: Helicopter evacuation will bear a cost. The evacuation choice will be at the sole discretion of the Organizers who will  evaluate the situation according to the Emergency Plan. The means of evacuation and the hospitalization location will be at the sole  discretion of the Medical Director. 

Any expenses arising from the admission of a runner to either a public or private health institution for medical tests, surgeries, and  medicines, as well as transportation and any recovery expenses, are to be borne by the runner and the runner’s medical insurance  provider.  

4.8 – Runner’s commitment 

In order to participate in this race, it is essential that runners: 

  • are conscious of the distance and technical features of the course and are thoroughly prepared for such a challenge are quite self-sufficient in a mountain environment so as to solve any problems that may arise in a race like this know how to face, without any assistance, weather conditions that may be highly adverse due to the altitude and the  geographical features (night, wind, cold, fog, rain, or snow) 
  • can manage, even in isolation, the physical and mental distress caused by extreme fatigue, digestive problems, muscle or  joint pain, and minor injuries.  
  • are fully aware that in a mountain race like this, safety depends on the ability of the runner to adapt to the problems that  can either be or not be anticipated. 


The following features of El Paso Austral- Ultra Trail race must be considered by the participants before registering for the race.  5.1 – Semi self-sufficiency 

Semi self-sufficiency is defined as the capacity to be self-sufficient between supply points, both as regards to nutrition as well as  clothing and safety gear, all while being able to adapt to conditions that may or may not be anticipated (adverse weather, physical  conditions, injuries, etc.). Runners should bear in mind that the race is carried out in a single stage to be run at each individual’s  pace within the timeframe established through cut-off times by the Organizers.  

This principle specifically implies the following rules: 

  • Each runner must carry his/her mandatory equipment (see “Mandatory equipment”) at all times during the race You must  carry your belongings in a backpack (or similar gear) that will be marked at the check-in and cannot be changed along the  course. At any time during the race the controllers may verify the backpack (or similar gear) and its contents. The runner  must submit to these controls with good will under the penalty of disqualification. 
  • Designated supply points will have food and beverages available to be consumed at that spot, thus avoiding litter on the  course. The Organizers will only supply mineral water or energy drinks to refill your bottle or hydration vest. When leaving  each of the supply points, the runner must evaluate the amount of food and drinks he or she will need to reach the next  supply point or the finish line. 
  • Runners must not be escorted or accept to be escorted during the entire or any part of the course by a person who is not  officially registered with the race. 
  • With the aim of ensuring the semi self-sufficiency spirit of this race, controllers may report such irregularities to the Sports  Director for penalization. 

5.2 – Aid stations (PAS) 

There will be several supply and aid stations along the course where not only food and beverages will be provided for the runners  but also medical assistance, if required. These stations can be seen in the datasheet and guide for each distance on the official  website. 

5.3 Checkpoints (PC) 

The Organizers will arrange several Checkpoints throughout the course to monitor and guarantee that runners have passed specific  points and to check the mandatory equipment, if the Checkpoint Manager so decides. If any of the mandatory items of equipment  are found missing, the runner may be disqualified. At all times the Organizers will be strict and uncompromising regarding this issue  because the safety and the semi self-sufficiency of runners is of paramount importance.  

5.4 – Medical assistance station 

Several aid stations and medical assistance stations will be distributed throughout the course and identified in the runner’s guide.  Medical tents will be located in Pampa Linda and in the finish area. They will be available during the entire race. Runners experiencing a severe health condition may receive medical assistance. If necessary, the attending physician will evaluate whether  the runner needs to be referred to a medical facility.  

A runner who is experiencing difficulties shall be responsible for requesting assistance as follows:  

  • Entering the nearest aid station by his/her own means  
  • Asking another runner to get assistance. In that case, be specific with the information to be relayed: location and reason  why help is needed. 

It is important to remember that, given the characteristics of the race and the terrain on which it is held, it may take a long time for  help to arrive. Therefore, it is essential to utilize the first aid kit for self-assistance and any personal experience the runner may have in these types of circumstances. 

Official rescue personnel and doctors, as well as any other person authorized by the Directors may:  

  • Stop a runner if they consider he or she is not in a satisfactory condition of health to continue the race. Check the mandatory equipment. 
  • Evacuate runners who they deem at risk using any means necessary. 
  • Hospitalize any runner that so requires due to his or her health condition.  

5.5 – Course marking 

The course will be properly marked with tape from the race organizers, fixed signs, light signals, cairns, and signs with reflective  material to reflect the light of the headlamp. 

WARNING: If you don’t see the marks on the course, do not continue. Go back to the last mark you saw and continue on the correct  trail. 

We respect our environment and do not use paint for marking the trails. The existing paint marks are those done by the national  park.  

5.6 – Cut-off times  

Cut-off times will be posted on the official website, in the technical datasheet for each distance, and in the runner’s guides.

Runners who miss the cut off and are in good shape must self-evacuate and make their way by their own means to the nearest  vehicle access point or aid station.  

5.7 – Finish line 

  • The finish line for the 50K course will be located within the property of the Hostería Pampa Linda.  The finish line for the 70K and 120K distances will be in the area of the Estuario de Reloncaví, the fjord on the mouth of  Petrohue River (Chile) with a view of the Pacific Ocean. This location is 40km away from Ensenada and 79km away from  Puerto Varas. 

Upon crossing the finish line, runners will receive a finisher medal and will be given access to the recovery zone where the following  services will be provided:

The Organizers will rely on the “App Movil” system for instant race timing.  


El Paso Austral- Ultra Trail requires long distance trail-running experience in the mountains. In order to participate, being self sufficient is the most important part. The Organizers will be available to ensure the security of each runner and to assist as  necessary.  

In the case of withdrawing from the race due to fatigue, a minor injury, or cut-off time, assuming the runner is in good condition, he  or she should return to the closest aid station or the finish line in order to be transferred to the transport to Bariloche. In this case,  the Organizers must be notified. 

In the event a runner must withdraw from the race due to an accident or a major injury where the medical team makes the decision  to not continue the race, the participant will be evacuated and transferred by the Organizers. 


The Race Director, Sports Director and the Checkpoint Manager are responsible for enforcing the regulations and may promptly  apply penalties or disqualify runners as necessary.

In the case of force majeure such as very unfavorable weather conditions or other circumstances that may affect the safety of the  participants, the Organizers reserve the right to: 

  • change the start time 
  • cancel the race  
  • postpone the race a few hours  
  • stop the race while in progress

11.2 Protection of personal information 

The personal information of each participant is vitally important to the Organizers, therefore it is crucial to have the correct  information. This database will be used to identify each individual runner in order to communicate before, during, or after the  event any information related to his or her participation, as well as in the event of a possible emergency. All the information of the  runner will be used internally by the Organizers. Any request to modify the personal data should be sent to  info@elpasoaustral.com no more than 15 days before the check-in day established by the Organizers.

Every person who is part of this event, whether they are staff of the Organizers, Suppliers, or Participants take responsibility for  respecting the environment and the natural area where the race is held. 


  • It is strictly prohibited to leave trash (gel packs, paper, organic waste, packaging, etc.) on the trail or in any area where the  event is held. There are trash receptacles at each aid station (PAS) and they must be utilized. The “Environmental  Commissioners” will be patrolling along the course. 
  • All participants should carry their trash and packaging until they can properly dispose of them in the trash containers at the  supply points or the end of the race. The Organizers advise the use of a bag provided in the runner’s kit to carry the trash. It is required to follow the trail that has been marked, without making shortcuts. Leaving a trail causes erosion and damage  to the site.
