The race-bib must be collected in Chamonix at la place du triangle de l’Amitié between 14:00 and 16:30.

The race bib must be worn on the chest or the stomach and must be permanently and fully visible throughout the entire race. It must, therefore, always be positioned over any clothing and cannot for any reason be fixed onto the back or a leg. The name and logo of the sponsors must neither be modified, nor hidden.  The race number is the pass necessary to get to the shuttles, buses, refreshment posts, nurses, rest areas, showers, areas for depositing or recuperating spares bags…Except in the case of refusal to comply with a decision taken by a race official, the race bib is never withdrawn, but in the case of retirement, it is deactivated.


First aid posts are positioned at different points throughout the course. These posts are in radio or telephone liaison with Race Control. A medical control team is present during the entire duration of the events at the Chamonix Race Control. The rescue posts are aimed at bringing help to any person in danger with the means particular to the organisation or registered.

If it appears that a runner is in difficulty or seriously injured to call for assistance :

• go in person to a first aid point • telephone the course controller

• ask another runner to alert the first aiders It is essential that each runner helps anybody in danger and alerts the first aid point.

Do not forgot, that due to the problems related to the environment and the type of event, one might have to wait for assistance for longer than anticipated. Your security, therefore, depends upon the quality of the materials that you have in your pack.


Each runner is equipped with 2 electronic chips: 1 fixed to the race-bib and 1 fixed to the back-pack.

Runners who are not in permanent possession of their chips will be penalised. The first automatic control is made when crossing the starting line. To avoid all unnecessary searching, all participants are obliged to notify their abandonment as soon as possible, at a control post or by telephone to the race HQ (PC course).

Following their abandonment, each runner whose state of health does not require an evacuation, must return as fast as possible, by their own means, to the finishing area.


The Yrun takes place in autonomy. No refreshments will be organised along the route.

Refreshments, food and drink, will be available at the arrival area in Chamonix on the the day of the Prologue (Tuesday) and on the Champs du Savoy (Wednesday).
