a) The organization of Patagonia Run 2026 is led by Spartan Race S.A.U.

b) The organization has a Race Management Team that will oversee compliance with these regulations by competitors and will make decisions regarding any matter related to the race. Any participant with questions about the course, race, rankings, etc., must contact the Race Management Team via email at info@patagoniarun.com

c) Any dispute regarding a participant’s ranking or compliance with the applicable regulations will be resolved with final and non-appealable judgment by the Race Director.

d) As this is a trail event with mountain routes that are frequently redesigned for various reasons, the distances and elevation profiles indicated for each category are approximate.

e) The Organization may suspend and/or postpone the event due to public safety issues, public events, vandalism, weather conditions, pandemics, and/or health reasons of any kind and/or force majeure.
In the event of race cancellation due to reasons beyond and/or not attributable to the Organization, including those outlined in the first paragraph of this section, the paid registration will be credited toward the next edition of the event, with no additional cost to the runner. Registration fees are non-refundable.

f) Weather conditions and other circumstances may force the Organization to redesign the course, modify start times, or adjust cutoff times at various points in the race for safety reasons. In such cases, any changes will be communicated through the official race social media. Even during the race, the route may be modified for safety reasons, and in all cases, changes will be clearly marked.

g) The Organization may prevent a participant from continuing in the race if advised by the medical staff. The Organization may also modify distances, routes, and schedules due to weather, safety, and/or other reasons. These decisions shall not be subject to claims against the Organization, sponsors, and/or medical staff.

h) The Organization, its Sponsors, and the official race photographers reserve the right to use, reproduce, distribute, and/or publish photographs, films, videos, recordings, and/or any other type of media—including social media and content from the Spartan circuit—of the runners without any financial compensation. Each runner’s registration implies consent to the use of their image as described above.

i) Participation in the race implies full responsibility for the data provided in the registration form, full acceptance of the rules, terms and conditions of the event, and payment of the registration fee.

j) Minors under 18 years old who are at least 12 years old on race day may participate in the 10k race. Those who are 14 years old on race day may participate in the 21k race. Those who are 16 years old on race day may participate in the 42k in the Youth Category. The Youth Category is non-competitive and does not count toward the General Awards of the 42k, which are reserved for participants over 18 years old.
In these cases, the informed consent and authorization form must be signed by the participant’s parent and/or legal guardian. If the parent or guardian is not present at the time of accreditation, the underage participant must present the signed consent form, with signature certified by a Notary Public.
Under no circumstances will minors under 18 be allowed to compete in the 70k, 110k, or 100Mi races, as there is no global medical consensus regarding the minimum age for ultramarathon distances (70k, 110k, and 100Mi) without health risks.

k) Requirements to participate in the 100Mi distance: To participate in the 100Mi distance, one of the following four requirements must be met. These will be evaluated by the Organizing Committee, which will determine authorization for participation in this distance.

1) Have at least 12 ITRA Points earned in a maximum of 3 races between 2024 and 2026, with at least one race being equal to or greater than 110 kilometers non-stop.
2) Have been a finisher in any of the following races:
– 110k Patagonia Run 2024 or 2025 within the official cutoff time.
– 100Mi Patagonia Run 2024 or 2025
3) Have been a finisher between 2024 and 2026 of another non-stop race similar in distance and elevation profile to those mentioned in point 2). To do so, the runner must provide proof of finishing times by uploading links to official results in the pre-registration/application form for the Organizing Committee’s evaluation.

l) Athletes who are currently suspended, or who have been proven to use prohibited substances, or who are serving any form of ineligibility imposed by national or international federations or confederations at the time of the event, are not allowed to participate.

m) The Organization reserves the right to admission and continued participation in the race.

n) The Organization will not allow participation of athletes who have been sanctioned in previous editions of this race or in races organized by TMX Team and/or NQN Eventos and/or Spartan Race S.A.U. and/or who belong to the Spartan Trail circuit.

o) The race number (bib) received at accreditation must be worn and displayed throughout the race in a visible position on the front of the shirt, sweatshirt, jacket, or thigh. Any runner who alters their race number in any way will be disqualified.

p) The Organization will track each runner’s times using either timing chips or manual methods. It is mandatory to pass over the timing mats at the Start, all Control and Aid Stations, and the Finish Line in order to appear in the official results. The chip time is for reference only. The classification time used will be the total time from the exact start time of the corresponding race.

q) Assistance is not allowed at any point along the course. It is the sole responsibility of the runner to refuse any unauthorized assistance. Receiving any type of “external” assistance (i.e., not provided by the organization’s staff or another registered runner in the same race) will result in disqualification.

Exclusive for 100Mi: participants in this distance may have one person as an external support crew. This assistance will be allowed only at specific points determined by the Organization. This support person must be accredited by the runner during the check-in process. Details about external assistance are described in the 100Mi Runner’s Guide.

There will be 3 Full Aid Stations for the 100Mi distance, 2 Full Aid Stations for the 110k distance, and 1 Full Aid Station for both the 42k and 70k distances, where personal items may be sent. For this purpose, one drop bag per Full Aid Station may be submitted, which will be provided by the Organization. The weight of the bag transported by the Organization may not exceed 3 kg, except for the 100Mi bag sent to PAS Colorado, which may weigh up to 5 kg. Bags will be weighed upon delivery. Drop bags will not be refrigerated. The Organization is not responsible for the loss of bags or their contents.

r) Only runners who complete the full official course of their registered distance will be classified.

s) Runners who do not complete the full distance will be classified as DNF (international acronym = Did Not Finish).

No certifications will be issued for partial distances. For example, if a runner registers for the 110k and only reaches km 70, no certificate will be issued for the distance completed.

Runners who finish their distance after the official cutoff time will appear as “FINISHER outside classification,” even if they cross the finish line. The Organization reserves the right to extend the race time or modify cutoff times at any moment in the case of extraordinary circumstances.

t) If a runner sees another participant in distress, they must report it to the Organization.

u) In the event of withdrawal, the runner has the non-delegable obligation to inform the Organization. The notification must be made only at the Aid Stations (PAS), at the Start, or at the Finish Line. Flaggers or personnel outside of these locations are not authorized to register a withdrawal notice. It is very important to report a withdrawal; otherwise, the runner will be presumed missing, which may cause avoidable complications.

v) Runners must report if they are undergoing medical treatment, present certificates and prescriptions, and disclose any substances they are taking. This communication must be made via email to info@patagoniarun.com

a) According to Article 34 of Law 24.240 on Consumer Protection, the registration fee may be refunded within 10 calendar days from the date the contract is signed. To request a refund, please contact us via email at info@patagoniarun.com.

b) After the period mentioned in the previous section has elapsed, the registration fee is NON-refundable AND non-transferable to another person in case the runner does not participate, regardless of the reason.

c) In cases where the participant informs their decision not to participate, for any reason, and the 10-day period mentioned in section a) of this article has passed, the Organization may recognize a percentage of the registration fee to be used as a discount for the Patagonia Run 2027 edition exclusively, depending on the date the competitor reports their non-participation and provided their payment plan is up to date, as follows:

– 100% of the 2027 registration value if the 2026 registration has been fully paid, and the participant informs their non-participation before February 28, 2026.
– 75% of the 2027 registration value if the 2026 registration has been fully paid, and the participant informs their non-participation between March 1 and March 31, 2026.

As of April 1, 2026, if unable to attend the event, the runner must notify their non-participation by email to info@patagoniarun.com, justifying the reason, and the Organizing Committee will evaluate each case individually and may grant a special discount to be used for the next edition’s registration.

To request the cancellation of their registration, the participant must send the request via email to info@patagoniarun.com. Verbal or phone requests and/or communications will not be valid. Only requests sent by email to info@patagoniarun.com will be accepted.

a) Medical certificate, required for all distances, stating: Runner’s full name, ID number, and a statement confirming the runner is medically and physically fit to participate in – clearly indicating – the distance they will run. It must be dated in 2026 and include the doctor’s signature and stamp.

b) The assigned race bib is MANDATORY for ALL distances and must be visibly worn on the front of the shirt, sweatshirt, jacket, or thigh throughout the entire race.

c) Race wristband properly worn, for all distances.

d) Emergency or nautical whistle, mandatory for ALL distances.

e) Mandatory headlamp or handheld light of 200 lumens or more, for the following distances: 42k – 1 light; 70k, 110k, and 100Mi – 2 lights, as follows:

IT IS MANDATORY THAT EVERY RUNNER in 42k, 70k, 110k, and 100Mi START THE RACE WITH THE LIGHT ON AND WORN, AND CARRY IT THROUGHOUT THE ENTIRE COURSE, regardless of daylight, ensuring safety and preparedness for any situation. Participants in 70k, 110k, and 100Mi are strongly recommended to carry both required lights to avoid being pulled from the course in case one fails. Lights must be worn from 5:00 p.m., turned on by 6:45 p.m., and remain on until 8:00 a.m.

Along the course, runners may be asked to show their safety gear, including the light, and confirm it is functional. Those without gear or with non-functional gear will be disqualified and may not continue on the course.

Runners with lights off, in red mode, or not meeting the required brightness during the mandatory hours will be held on the course until sunrise or not allowed to continue after 6:45 p.m. We will strictly enforce lighting requirements, as it is a critical safety element.

Participants in the 42k and 70k must start with the light on. If still on the course after 5:00 p.m., they must wear the light and have it turned on by 6:45 p.m. until they finish.

110k participants must start with the lights on and keep them on until 8:00 a.m. Additionally, from 5:00 p.m. onward, they must wear the light and keep it on starting at 6:45 p.m.

100Mi participants must have one light worn at the start for pre-race check. After the start, they must wear the light from 5:00 p.m. (either Friday or Saturday) and keep it turned on from 6:45 p.m. until 8:00 a.m.

f) Survival blanket mandatory for 21k, 42k, 70k, 110k, and 100Mi.

i) Zip-lock bags (Ziploc type) to store food provided at aid stations. Required for ALL distances.

j) When the forecasted minimum temperature along any part of the course is extreme or the organizers consider it higher risk, the Organization may require the following items to be carried in the runner’s backpack for all distances:

– Long tights or warm pants.
– Windbreaker jacket.
– Fleece or warm jacket.
– Gloves.
– Fleece hat or similar.

This will be confirmed during the race briefing and/or the day before the race start.
