To participate in a UTMB event, in particular it is essential: To be completely aware of the length and difficulty of the event and to be adequately prepared for it. To have acquired, before to the race, a real understanding of personal autonomy in the mountains/terrain allowing for the management of potential problems encountered during this type of event, notably:
- Ability to confront, without outside assistance, changing climatic conditions which could be very difficult to deal with at altitude (night, wind, cold, fog, rain or snow).
- Ability to manage, including when one is isolated, physical or mental problems arising from a heavy fatigue, digestive problems, muscle or articular/joint pains, small wounds, etc...
- Aware that the organization’s role is not to help a runner manage these problems.
- Aware that for such an activity in the mountains, safety depends upon the runner's ability to adapt to the problems encountered or foreseen.
- To inform and educate the runner’s supporters towards the respect of nature, people, and the regulations of the race.
Participants are expected to demonstrate the principles of semi-autonomy/self-sufficiency. They should be prepared to carry their own fluids, food, and gear (including inclement weather gear) between aid stations. Participants should also be prepared, within the course safety guidelines, to handle adverse or changing conditions. This self-sufficiency principle implies the following rules:
Throughout the duration of the race each runner must have with them all their mandatory equipment. This equipment will be carried in a pack (backpack or belt) and cannot be changed along the race route. At any moment of the race, the race stewards/marshals can verify the pack and its contents. The runner is obligated to comply with these gear checks. Any non-compliant runner is at the risk of disqualification from the race.
The aid stations provide drinks and food to be consumed on site. The race organizer only provides still water and/or sports/electrolyte drink for filling water bottles or hydration packs. The runner should take care to ensure they have, when leaving each aid station, the appropriate quantity of drink and food to keep them going until the following aid station.
For races of the 100M, 100K and 50K, a personal assistant is allowed at certain aid stations (*), in the area specifically reserved for this use and at the discretion of the team leader. Only one person is allowed to provide assistance, which only includes providing the runner a bag with a maximum volume of 30 liters. Medical assistance given by a member of the runner’s crew, is strictly forbidden, only small cares are allowed like massage and treating a blister as long as the runner remain seated on a chair and does have to lie. The rest of the aid station is strictly reserved for the runners.
It is forbidden to accompany or be accompanied along any part the race route by a person not registered for the race, outside of the spectator run zones which are clearly marked in the proximity of the aid stations. A participant who accepts being accompanied outside of the designated zones violates the principle of self-sufficiency. The assistance zone begins 500m before and ends 500m after the aid station, and there is only one assistant allowed per runner. The race stewards/marshals or team leaders, witnessing this violation, are authorized to penalize the participant in order to enforce the rules. Runners are not allowed to participate with a dog or any other animal, including service animals.
The list of places where assistance is tolerated is available on the website race pages.
In order to ensure their safety, each participant must carry with them all the items listed in the mandatory equipment checklist and must carry all the equipment with them during the duration of the race even if the runner is not using it. Organized and/or random equipment checks will be carried out during the race. A penalty up to and including disqualification will be applied to runners who do not have all the mandatory equipment with them (see PENALTIES).
Please note: the items included in the mandatory equipment checklist are the basic pieces of equipment each runner must carry with them. It is important not to choose the lightest possible clothing. Instead runners should pack clothing that provides adequate protection in the mountains/course terrain against bad weather conditions, including cold, wind, heavy precipitation and snow and will be a better protection and allow better performances. It is important to pack all this equipment in a way that preserves it from rain/snow and keeps it dry when it needs to be used (for example, using waterproof plastic bags). List of mandatory equipment is available on the website race pages
All clothing items must fit the runner - in terms of size - and they must not be altered in any way after leaving the factory. The mandatory gear must be carried in a running pack or belt for the duration of the whole race and must not be changed during the race.
In order to reduce plastic waste, no disposable dishes (cutlery, cups, bowls) will be distributed at any check point or aid station. We invite you to Bring Your Own Utensils (BYOU) if you wish to eat hot meals at the aid stations.
If runners choose to take hiking poles with them, they must carry them for the entire duration of the race. It is forbidden to start without poles and get them during the course of the race. No poles are authorized in the spare bags. The use of poles may be prohibited in certain areas marked by specific signs along the course, for safety or environmental reasons.
If you have further questions about mandatory equipment, do not hesitate to consult the organization.
Music: Listening to music using earphones only, is tolerated, so long as it is safe to do so. Any earphones MUST be removed when crossing any roads, as well as on approach to, and whist at, any checkpoints and when approaching and passing any Safety Team members
Race-bibs are handed over to each runner upon presentation of:
• A valid ID with photo
The race-bib must be worn on the front of torso at all times and must remain completely visible during the entire race.
It must always be placed on top of all clothing and must not be positioned on a leg or on the pack. The runner’s name and partner's logos must not be altered or hidden. The bib is the pass to access the organization transportation, aid stations, medical points, rest rooms, showers, bag drop-off or pick-up areas. The bib is only withdrawn if the runner refuses to comply with the race director’s instruction. If the runner withdraws from the race, the race bib will be cut.
At the race-pack collection, each participant receives at least a 30-liter bag. After filling the bag with the items of their choice and closing them, runners can drop them off at the dedicated event area.
For logistics reasons, UTMB World series events only accept the UTMB World series spare bags that are distributed during the check-In. Those bags are reusable, so we ask the runners who already have received one of those bags to reuse it each time they take part in a UTMB World Series event.
How to get your bags at the finish area: The bags are returned to either the runner or a family member or friend, only upon presentation of the race-bib. The bags must be retrieved no later than 2 hours after the end of the race.
For any runner that drops out of the race, the organization will take the bags to the finish area, as long as the runner’s withdrawal is registered with the race organizer. Because of logistical factors, the organization cannot guarantee that all bags are brought before the end of the race.
Only bags supplied by the organization will be transported. Poles are not allowed in these bags. As the items in the bags are neither checked nor controlled, the race organizer is not responsible for the items in the bags. We recommend not to put any valuable items in the bags. We advise runners to keep toiletries and spare clothes at their accommodation.
See drop bags location on the website race pages
When registering for one of the UTMB® events, participants agree to respect the environment and the natural areas they pass through. In particular:
- Littering is strictly forbidden (gel tubes, paper, organic detritus, plastic wrappers...). Trash/rubbish bins are available at each aid-station and they must be used. The race stewards will be checking all along the race route.
- All participants must keep their rubbish and wrappers with them until they can throw them in the bins at an aid station. Runners should carry a bag or pouch to carry their waste to the next bin. Plastic bags for soiled paper are handed out with the race-bibs. They must be used for collecting any paper used during any urgent need along the route.
- All runners must follow the paths as they are way-marked, without short-cutting them. Actually, short cutting a path causes erosion thus damaging the site.
- No disposable dishes (cutlery, cups, bowls) will be distributed at any check point or aid station. This is to reduce plastic waste by runners, as well as by the volunteers of the UTMB®. We invite you to bring your own utensils if you wish to eat hot meals at the aid stations.
Along the race route, there are points where runners are provided food and drinks. Aid stations supply drinks and food for consuming within the aid stations. The organization supplies still water and electrolyte/sports drink for filling the mandatory water bottles/hydration packs and personal collapsible cups. The runner must make sure, when leaving the aid station, that they have the necessary quantity of food and drinks to keep them going until the next aid station. **To enter the aid stations, runners must wear their race-bib. ** The race guide and the relevant pages on our website provide full list of aid stations and what kind of food/drinks runners may find there.
Runners are checked upon arrival at an aid station and at some security points along the course. Unexpected check points are set up along the route. Their location will not be publicized.
Way markers are made of a reflective material that catches the light from the runner’s headlamp, so that they are easily visible at night.
WARNING: if you can't see any way markers, turn back!
Because we respect the environment, we do not use any paint on the trails.
There are several medical stations along the route. These stations are directly linked to the command center. There is medical staff at the command center or on the course during the events. Medical stations are intended to assist any runner in need of medical assistance. It is up to a runner in need of assistance or injured to call for help:
- By going to a medical station
- By calling the command center (phone number should be saved in mobile/cellphone)
- By asking another runner to call for help
- By using the SOS function on the LiveRun app (if applicable)
Runners must provide assistance to any person in danger and alert the command center.
If a runner is unable to call the command center, and only if it is an absolute emergency, runners may call directly one of the national security services (especially if you are crossing an area where only emergency calls are possible): local emergency number will be specify on the race guide.
A number of unexpected events, including inclement weather events, could make you wait for help longer than expected. Your safety therefore depends upon the quality of the items that you have put in your pack.
All medical, paramedical, first aid and guide staff, as well as any person appointed by the race direction are able to:
- Remove any participant who is deemed unable to continue the event
- Demand any competitor to use any item of the mandatory equipment
- Evacuate any runners deemed to be in danger
- Refer runners to the most appropriate care facility
A runner who is treated by a doctor or reached by the search and rescue staff will defer to the professional’s authority and agrees to accept their decisions.
If a runner's state of health justifies treatment via intravenous drip, the runner shall compulsorily withdraw from the race.
There is a medical center at the finish area available for runners with severe medical problems. Comfort care is based on the decision of the medical staff within the limits of care available.
Runners must stay on the marked path, even when they sleep.
All runners who voluntarily venture from the way-marked course are no longer under the responsibility of the organization.
You may find the time limit (cut-off times) for leaving the main aid stations on the event web site and in the Runner's Guide. In case of any changes (see Exceptional Conditions), the new cut-off times will be announced via SMS/text message.
When start is organized in several waves, the maximum authorized time and time barriers are calculated taking into account the departure time of the runners from the LAST wave.
Cut-off times are calculated to allow participants to reach the finish within the time limit. In order to be authorized to continue a race, all participants must leave the check point/aid station before the cut-off time (whatever their time of arrival at the check point).
All runners who drop out, are stopped by the organization, or are behind official time barriers are not allowed to continue the race. Their bib will be cut and they will be transported back to the event area by the organization transportation.
Time limit and cut off times are specified on the website race pages.
Except in case of injury, a runner wishing to withdraw the race must do so only at a check point. They must inform the person responsible for the point or report their withdrawal via the LiveRun app (if applicable) and inform the command center.
If a runner wishes to withdraw while on the route between two checkpoints, he/she must reach the nearest checkpoint where he/she must report their withdrawal.
Runners who withdraw must keep their race bib because it is the pass to access organization transport, meals, treatment rooms...
Repatriation works as follows:
- Vehicules are available at some aid stations to take runners who drop out back to finish line.
- Runners who drop out at any other aid station or check point but whose state of health does not require them to be evacuated must return as quickly as possible and by their own means to the nearest point of repatriation.
- For aid stations or security points accessible by car or 4x4:
- after the closing of the aid station/security points, the organization might repatriate any runners who have abandoned and haven't left the aid station yet.
- in the event of bad weather conditions justifying the partial or total stop of the race, the organization will make sure that all runners are transported as soon as possible.
During the race, runners will have some rest areas in some aid stations, with camp beds and blankets. Runners having finished their race and wishing to prolong their stay, must have their own accommodation.
All the post race services are listed on the website race pages
