Article 2 – Preliminary Considerations

This race takes place within Lanín National Park and its surrounding mountains and tracks. One of the key factors for success is clearly the magnificent scenery embracing the race. Therefore, local people and tourists are responsible for preserving this place. For this reason, we ask that you do not litter during the race and that instead you carry it to the Aid Stations or to the Finish Line. There will be garbage containers at the Aid Stations as well as 100 meters down the trail. Any runner who is caught by the Organization throwing garbage outside the places authorized for this purpose, will be disqualified. This decision is final.
Please be polite and respectful towards residents and neighbors, as they help to make this event possible, and with the wild, rural and urban environment. Always use toilets set up by the race organizers.
For safety reasons and to respect the experience of running on mountain trails and the contact with nature of all competitors, runners are not allowed to use loudspeakers and/or speakers.
Trail and ultra-Trail races require a level of fitness that may take months, or even years of training. Besides having the medical certificate that states that the participant has no physical handicaps or conditions and is fit to participate in the race they have registered for, each participant is responsible for their proper training for this type of race, and for being duly informed of the risks this activity entails, in order to enjoy Patagonia Run experience fully.
At online technical briefings offered by the organization team  at www.patagoniarun.com, runners will receive detailed information on technical aspects of the race course, preparation for weather and geographic factors, distances, altimetry, Aid and control Stations, mandatory elements and other recommendations they need in order to minimize risks end enjoy their experience fully. Such briefings are mandatory, as the information provided is crucial to all runners. Attending them to geta all the necessary information is stated in these Rules and Regulations, which all participants must know and agree to.  

Article 3 – General Considerations

a) Patagonia Run 2026 is organized by Spartan Race S.A.U.

b) The Race Directors will ensure compliance of these rules by all runners and decide on any issues related to the competition. All inquiries regarding course characteristics, competition, official times, etc. should be submitted to Patagonia Run Directors via email to info@patagoniarun.com.

c) Any controversy related to the timing of a runner, or compliance to the race Regulations will be resolved irrevocably by the Race Director.

d) This is a trail run event, where courses in the mountain may be frequently modified for different reasons. Therefore, the distances and altimetry indicated for each category are estimates.

e) The Race Directors may cancel and/or delay the competition due to public safety concerns, public acts, vandalism, weather conditions, pandemic and/or health reasons, and/or force majeure. If, for any reason unrelated to the Organization, including the reasons mentioned in the paragraph above, the race should be cancelled, all paid registration fees will be transferred at 100% to the next edition of the race, with no difference in cost for the participant. No fee reimbursements will be made.

f) Abnormal weather conditions or other unexpected event may force the Race Directors to modify the course, modify start times or cut-off times at the different points of the race for safety reasons, in which case, participants will be notified and informed of the new course. In the event of last minute changes, the modified course will be announced through the official networks of the race. The race markings could also be modified during the competition for safety reasons. All changes will be clearly marked.

g) The Organization may prevent a participant from continuing to participate in the competition, if advised by the medical staff. The Organization can also make changes in distances, routes and schedules due to weather factors. Such decision will not give the participant the right to any claim to the Organization, sponsors and/or medical staff.

h) The Race Directors and Sponsors reserve the right to use, reproduce, distribute and/or publish pictures, movies, videos and/or any other form of recording of the participants, including social media and those belonging to Spartan circuit, without having to provide any type of financial compensation. All runners should interpret registration to the event as their consent to these terms.

i) Participation in the race implies that the runner takes responsibility for the information provided in the registration form, full acceptance to abide by the rules and the terms and conditions of the competition, as well as to comply with the registration fees.

j) Underage runners who have turned 12 years of age before the date of the race may participate in the 10k race. Those who have turned 14 years of age before the date of the race may participate in the 21k . With 16 years completed on the day of the race, participants can compete in the 42k category Junior. The Junior category is of a participatory nature and does not qualify for the General Prize Awards for the 42k, which are exclusively for participants over 18 years old. In such case, a parent or legal guardian should sign both the registration form and the participant's waiver form. If the parent or legal guardian should not be present at accreditation, their signature will have to be notarized by a Public Notary. Under no circumstance, those athletes under 18 years of age will be allowed to participate in the 70k, 110k and 100Mi, since there is still no worldwide medical agreement on the age minor can participate in Ultramarathon distances (70k, 110k and 100Mi) without damage to their health.   

k) Registration conditions for 100Mi: These include mandatory Organization admittance for each athlete, according to his/her sports curriculum and at least one the following requirements:

In this case, runners need to include race finishing timing (race results internet links) as proof in the pre-registration form when applying for admittance to the Organization Committee. 

l) Runners who have been suspended, or who have been found to have used forbidden substances, or who are serving a disqualification period imposed by any Confederation or Federation may not participate in the race.

m) The Organization reserves its right of admission and stay in the race.

n) The Race Directors reserve the right to refuse admission to participants who have been penalized in previous editions of this race or in any race organized by TMX Team and/or NQN Eventos and/or Spartan Race S.A.U. and/or are part of Spartan Trail circuit.

o) Runners who tamper with their race number will be disqualified. Such number must be worn during all the race course, clearly visible in the front part of their t-shirt, sweatshirt or jacket.

p) The organization will time all runners, through the use of chips or manual system.In order to classify as a finisher, all runners will have to pass through the rubber mats at the starting line, at all Check Points and Aid Stations (PAS) and at the Finish Line. The chip time is only referential. The time used for classification is the total time from the start of the corresponding race.

q) Outside support by family and friends is not allowed at the Aid Stations or at any other part of the course. Runners will be responsible for rejecting any unauthorized assistance. In case of receiving any type of “external” assistance (assistance not provided by the organization's personnel or another competitor of that race), the penalty will be disqualification.
 
Exclusive for 100Mi: participants of this distance may have one (1) person as external assistance. This assistance will be allowed only at points determined by the organization. This assistant must be accredited by the runner during the accreditation process. The implementation of this external assistance is detailed in the 100Mi Participant Guide.

Participants are limited to one drop bag per full aid station. Drop bags will be provided by the Race Organization and should weight no more than 3 kgs (6.6 pounds), with the exception of the 100Mi bag that goes to PAS Colorado, which may weigh up to 5 kgs. Weigh will be controlled at reception. Bags will not be refrigerated. The Organization Team is not to be held responsible for the loss of any bags or its content. 

r) Only runners completing the full course for their distance will be included in the race ranking.

s) Runners who do not complete the full distance will be ranked as DNF (Did not finish). No partial distance certifications will be granted. For instance, if a participant registered for 110k completes only 70k of that course, they will not be ranked for the 70k distance. Runners completing the race after the Finish line Cut-off time will be ranked as “FINISHER outside Ranking”, even if they have crossed the finishing line.
