ASD SentieroUNO is a non-profit organization that organizes the races in collaboration with the Friuli Venezia Giulia Region and the municipalities involved. The events are organized on a non-profit basis, but with the aim of promoting the territory, the sport and the values of trail running. These principles form the foundation of the competitions, and the decisions of the competition management are always guided by them. The competitions offer qualifying points for the ITRA and UTMB circuits and are under the aegis of CONI and AICS. This regulation was drawn up on March 21, 2024.




To participate in an S1 Competitive event you must:

  1. Be fully aware of the length and specificity of the race and have adequate training.
  2. Having acquired, before the race, a real capacity for personal autonomy in the mountains that allows you to manage any problems relating to this type of race and, in particular:
    • Be able to face independently, without external help, climatic conditions that can be very difficult due to the altitude (night, wind, cold, fog, rain or snow);
    • Be able to independently manage physical or mental complications caused by extreme tiredness, gastrointestinal disorders, muscle or joint pain, minor injuries, etc.
    • Be fully aware that the role of the organization is not to assist runners in managing their problems and that, in a mountain activity, safety depends above all on the competitor's ability to adapt to problems encountered or foreseeable.
    • Inform and make your companions aware of respect for places, people and the rules of the race.
    • Have a competitive medical certificate valid for athletics, cross-country skiing, triathlon, cycling or swimming, for Italian citizens only and for non-Italian citizens registered in Italy with a sports promotion federation or body recognized by CONI.




SentieroUNO events are non-profit and aim to promote the territory and the spirit of trail running. For this reason, the organization has decided to offer maximum flexibility in registration, with a basic fee that includes the essential race services and allows you to add, at the participant's discretion and according to his economic possibilities, additional services and options. 





  • Breastplate
  • Access to refreshment points
  • Medical assistance
  • Finisher medal


  • Insurance for cancellation, with or without reasons, by the competitor. Available in your runner area.
  • Personal insurance for post-hospital accident treatment.
  • Shuttle transportation to the starting line or after the race. Available in your runner area.
  • Additional services that can be booked on request: photos, shipping of materials, race pack, technical clothing, pre- and post-race accommodation and meals, delivery of bags to the starting line, personal taxi service.




The transfer of the basic fee to other S1 events or to the following year is permitted, free of charge, no later than 30 days after the start of the event. There are no cash refunds, but the transfer of the fee is possible according to the conditions established during registration. Other forms of transfer and insurance are available by subscribing to extra options.




It is essential to respect the principle of individual competition in semi-self-sufficiency. Semi-sufficiency is defined as the ability to be autonomous between two refreshment points, both in terms of nutrition and with regards to material and safety, and to be able to adapt to any unexpected or foreseeable problems (adverse weather conditions, physical problems, accidents...). This principle is based on the following rules:

  • The competitor must bring with him all the mandatory material for the entire duration of the race (see the EQUIPMENT paragraph). This material must be carried in the backpack, which must remain the same throughout the entire route. At any time, the race commissioners can carry out checks of the backpack and its contents. The competitor is required to undergo these checks with cordiality, otherwise he will be subject to exclusion from the race.
  • The refreshment points offer drinks and food to be consumed on site. The organizers only provide water or energy drinks to fill water bottles or camelbaks. Leaving a aid station, the runner must ensure that they have the necessary amount of food and drink to reach the next aid station.
  • Personal assistance is permitted only at refreshment points.
  • Medical assistance by a member of the runner's team is strictly prohibited. Only minor care, such as massage or blister treatments, is permitted, as long as the runner remains seated in a chair and not lying down.
  • It is forbidden to be accompanied or accompanied along any part of the route by a person not registered for the race, except in areas near the assistance points. A participant who is accompanied during the race violates the principle of semi-autonomy. Race officials or staff members who witness this violation are authorized to sanction the participant to ensure compliance with the rules.

Runners are not permitted to participate with a dog or any other animal, including service animals, without prior authorization obtained after a case-by-case evaluation.



Article 7 – EQUIPMENT

For safety reasons, each participant must bring with them all items listed in the mandatory material section indicated on the web page relating to their distance. It is necessary to have all the material with you for the entire duration of the race, even if it is not used. During the race, both organized and random checks will be carried out on the material. Runners who do not have all the mandatory equipment will be subject to penalties, which may go up to disqualification (see PENALTIES). It is important to note that the mandatory equipment list includes essential items that every runner must bring. You should not opt for the lightest clothing possible; on the contrary, it is recommended to have clothing that offers adequate protection in the mountains and along the route against adverse weather conditions (cold, wind, pouring rain and snow), thus ensuring greater safety and better performance. If the competitor decides to use poles, he must carry them with him for the entire duration of the race. It is forbidden to leave without poles and collect them along the route. It is not possible to deposit the sticks in the bag of personal effects for reasons of safety and integrity of both your own bag and those of others. If you have any questions about the mandatory material, please contact the organization. The use of headphones to listen to music is tolerated, as long as it is done safely. However, it is mandatory to remove your earphones when crossing streets, as well as when approaching any checkpoint and members of the security team.



Article 8 – BIB

It is possible to collect the bib number of other competitors after completing, by the delegating party, the collection delegation fields in the competitor area. The bib must be worn, if possible, on the front part of the body (chest or belly) and remain visible at all times for the entire duration of the race. Therefore, it must always be placed over clothes and can be fixed on the backpack or on a leg, in order to guarantee perfect visibility. Sponsor names and logos must not be changed or hidden. The bib is essential to access the organization's shuttles, refreshment points, medical points, rest rooms, showers, bag storage and recovery areas, etc.




The bags and personal bags are kept in a video-monitored area, but managed independently by the competitors, who personally take care of the deposit and collection of their bags. Bags must be collected no later than 2 hours after the end of the race. The organization undertakes to guarantee the return of the bags to the arrival area, provided that they have been deposited according to the instructions provided. Sticks cannot be transported by the organization. Complaints regarding the contents of the bags are not allowed, as it is not verified, consequently, the organization does not assume responsibility. We do not recommend placing valuables in bags and we recommend keeping toiletries and changes of clothes at your accommodation. For some distances, the option of dropping off bags at the starting line may be available; this service can be booked with a supplement from your runner area. Detailed information on the times, methods and places of delivery of the bags is available on the race page.



Article 10 – SHOWERS

An outdoor shower service is available at the end of the race. The organization does not assume responsibility for objects left in the changing rooms or cloakrooms; for hygiene and safety reasons, at the end of the race, any objects left behind will be removed.



Article 11 – SHUTTLES

There is no shuttle service.  



By registering for an S1 event, participants undertake to respect the environment and the natural spaces they pass through. In particular:

  • It is absolutely forbidden to throw waste along the route (gel tubes, papers, organic waste, plastic packaging, etc.). Bins are available at the refreshment points where competitors can dispose of waste. The Race Commissioners carry out surprise checks on the route.
  • Participants must keep their waste and packaging until it reaches the designated bins at the refreshment points. The organization invites competitors to bring a bag to transport waste.
  • It is mandatory to follow the marked paths, avoiding taking shortcuts. Cutting a path causes damage to erosion and the environment.
  • No disposable utensils (cutlery, cups, plates) will be distributed in the assistance areas and refreshment areas, to reduce the use of plastic by both runners and volunteers. Therefore, you are invited to bring your own utensils to consume hot food at the refreshment points.




The refreshment points offer drinks and food to be consumed on site. The organizers only provide water or energy drinks to fill water bottles or bags. When leaving a aid station, the runner must ensure that they have with them the amount of food and drink necessary to reach the next aid station. Only competitors with a clearly visible bib have access to refreshments. The list of refreshment points and available products is published on the event website and in the runner's guide.




Checks will be carried out in all refreshment points and in some aid stations. There will also be surprise checkpoints along the route, in addition to refreshment points and aid stations. Their whereabouts are not disclosed.




To facilitate visibility at night, the warning flags are equipped with reflective elements that reflect the light from headlamps. ATTENTION: if the signals are no longer visible, you need to retrace your steps! To respect the environment, colored chalk markings are used along the paths. The routes are marked, for the races that require it, with ribbons, arrows, paint marks or signs. However, it is the competitor's responsibility:

  • Be aware that most of the routes take place on forest paths and tracks where sudden deviations are possible. It is therefore essential to pay attention to the signs and, in the case of non-visible signs, go back to the last visible sign to check that you have not missed a crossroads.
  • Crossroads are signposted, where possible, with signs and arrows: one sign before the crossroads, one immediately after and a further confirmation sign.
  • It is recommended to always download the GPX tracks, even for races with signs, study the route and use exclusively the file provided via automatic email before the race. This version includes any small last minute changes. GPX tracks will only be provided to race competitors by email 48 hours before the race. 
  • In case of bad weather and fog, greater attention is required, as rain, snow or fog can significantly reduce the visibility of signs. This principle applies similarly to driving.




There are several aid stations along the route, connected by radio or telephone to the race headquarters (PC race). A medical control team will be active at the race PC or along the route for the entire duration of the event. These stations are intended to assist anyone in need of medical help. It is the responsibility of any runner in difficulty or injured to request assistance:

  • Going to an aid station
  • By calling the assistance number on the bib
  • Asking another runner to alert the emergency services
  • By sending a WhatsApp message to the number indicated on the bib. Each runner is required to assist people in danger and report the need for help. In case of impossibility to contact the race control center and only in absolute emergency situations, it is possible to call the emergency services directly, using the specific emergency numbers of each State, indicated in the runner's guide. Various environmental and race-related factors can prolong the wait to receive help; therefore, safety depends on the quality of the equipment in your race backpack.

Medical and paramedical staff, rescuers and guides, as well as any individual designated by the race direction, have the authority to:

  • Force any competitor judged unfit to continue the race to withdraw
  • Request the use of mandatory material
  • Evacuate runners deemed to be in danger by any means
  • Refer patients to the most appropriate medical care By accepting care, the runner submits to the authority of medical personnel and accepts their decisions. IV treatment entails the obligation to withdraw from the race. An infirmary will be available upon arrival for runners with health problems, with assistance based on the discretion of the medical staff. It is mandatory to stay on the marked route, even to sleep, and voluntarily moving away from the route excludes the organisation's responsibility.



The time barriers (maximum times) for leaving the refreshment points are available on the event website. Any changes will be communicated via SMS and WhatsApp. With departures in multiple brackets, the maximum authorized times and time barriers are the same for everyone and calculated to allow you to reach the finish line within the maximum time, including any stops. To continue the race, you must leave the checkpoint before the time limit, regardless of your arrival time. Runners who withdraw, are stopped or exceed the time barriers cannot continue, their bib will be cut off, and they will be transported to the main area by the organization. Time barriers and time limits are specified on the event website.




The competitor can withdraw from the race only at a checkpoint, except in cases of injury occurring along the route. You must inform the checkpoint manager or report your intention to withdraw via WhatsApp, as well as notifying the helpline number. In case of withdrawal in a section between two checkpoints, the competitor must reach the closest one and communicate his withdrawal to the person in charge. It is essential to keep your bib, which serves as a pass for access to shuttles, meals, the infirmary, etc. Return can take place in the following ways:

  • Return buses are available from some refreshment points, identified with the "bus" symbol on the maps and passage tables, to bring withdrawn competitors to the arrival area.
  • Competitors who withdraw at an aid station or a refreshment point not served by the shuttle, but in health conditions that do not require emergency transport, must reach the nearest return point as quickly as possible and independently.
  • As regards the refreshment or rescue points accessible by car or 4x4:
    • When the checkpoint closes, the organization can arrange for the return of the withdrawn competitors, based on the availability of vehicles.
    • In the event of adverse weather conditions requiring the total or partial interruption of the race, the organization undertakes to organize the return of the competitors as quickly as possible.



Article 19 – REST

During the race, runners will have rest areas available at some refreshment points, as indicated on the event page. Those who have completed the race and wish to extend their stay will have to provide their own accommodation.
