This is done to ensure the safety, security and equity for all. Every runner's relevant medical information is attached to the bib number and is referenced in case of medical intervention. The bib is also the source of truth if leading search and rescue efforts (name, phone number and emergency contact information). In the interest of everyone's safety, it is essential that each bib is worn exclusively by the person registered.

The following stations are accessible to spectators :

Yes, there will be random mandatory gear checks during the race. These can take place anywhere on the course.

Drop Bags are available only to 100K category runners.

At the race-pack collection, each participant will receive a 30-liter bag. After filling the bag with the items of their choice, labelling it and closing it, runners can drop them off at the start. For logistics reasons, UTMB World series events only accept the UTMB World series drop bags that are distributed during the check-in. These bags are reusable, so we ask the runners who have already received one 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.

Poles are permitted.

If you choose to use poles, it is for the duration of the race. It is forbidden to start without poles and retrieve them during the course of the race. Poles are not allowed in drop bags. The use of poles may be prohibited in certain areas that will be marked for safety or environmental reasons.

Yes, headphones are permitted. Listening to music is only allowed using headphones, provided it is safe to do so.

Headphones MUST be removed when crossing any road, approaching and while at any checkpoint, and when approaching or overtaking any member of the Safety Team.
