Assistance and support

Since 2003, we have come a long way! We started with one race with 700 runners: the event now gathers 10,000 runners from 100 nations and 7 races, each one with its own raison d'être. Even if the event is now renowned worldwide, its values have not changed: fair play, respect for people and for nature, hospitality... To ensure that everyone who participates in the UTMB® lives an unforgettable experience, a some rules must be respected along the race itinerary:


The runners, upon registering, have committed to respecting the regulations. Those accompanying them must do likewise to avoid putting them in the wrong with regard to their commitments.Reminder: running beside a participant outside of the zones, which are labelled as such in the proximity of the refreshment posts, is strictly forbidden and exposes the runner to a penalty of between 15 and 10 minutes. Concretely this penalty engenders a regression in the ranking and for certain runners it is the risk of not being within the time limit. Be careful not to confuse the zone of accompaniment (several hundred meters before and after each refreshment post, limits of which are clearly marked) with the zone of assistance (the area of the refreshment post reserved for this use). One could state that in the accompaniment zone you may only be accompanied not assisted!

Support Area

Personal assistance is tolerated only at certain refreshment posts, in the zone specifically reserved for this use, upon the presentation of an "Assistance" ticket (see below) and upon the agreement of the chief of post. This assistance can only be assured by one single person, without specific equipment other one than one bag of a volume of 30 litres maximum. Assistance given by a team professional, or any other professional person, medical or paramedical – even if they are a parent - is strictly forbidden.

1 ticket per assistance post
1 ticket = 1 person

(*) The personal asistance is tolerated in some points :

  • UTMB® : Les Contamines-Montjoie, Courmayeur, Champex, Trient, Vallorcine
  • CCC® : Champex, Trient, Vallorcine
  • TDS® : Bourg St Maurice, Beaufort, Les Contamines-Montjoie

Here are the only posts where you may receive assistance from family or friends. Only family type assistance is tolerated. All assistance at any other point along the route is forbidden.
On the OCC and MCC, no asistance will be tolerated on the race route. 

At the request of the elite runners, we would like to remind you that it is essential that they are left to run serenely. Please help ensure that their unique preoccupation is the management of their effort:

Respect their race space so that they can run without being hampered

Avoid crowding around a runner so as not to disturb them in their progression and concentration.

Protect their tranquility and the equity of the race

Respect the regulations: the race stewards are present throughout the race route.
