Duo Étoilé: team spirit
Duo Étoilé
Discover the special atmosphere of a 21km night race with1450m +/- , where team spirit and sharing are the key words: you'll leave with stars in your eyes!
To take part in this race, you'll need to have some experience of mountain running, be comfortable on all types of terrain and be self-sufficient for several hours. We draw your attention to the fact that a runner with an UTMB performance index of less than 240 points has very little chance of finishing the race, so we recommend that you take part in another Mont Blanc Marathon event.

Time barriers
The time limits given below are for guidance only. In the event of adverse weather conditions, and for safety reasons, the organization reserves the right to stop the event in progress or modify the time limits. All decisions will be taken by the race jury.
A runner arriving at a time barrier after the deadline will be disqualified. The lower right-hand corner of the race number will be "cut out" by the station chief and the runner will be invited to return to Chamonix. Should the runner wish to continue on the course, his or her number will be collected by the station chief and the runner will no longer be considered a participant in the Mont Blanc 90km, and will therefore no longer be under the responsibility of the organizer. Anyone disrespecting the volunteers responsible for enforcing the time limits will be banned from all Mont Blanc Marathon events.
