Difference in height
The flagship race of the weekend, 2nd stage of the Salomon Golden Trail World Series.
It brings together the best of the discipline who are engaged in a breathtaking battle in a dream setting.
First on the fast and rolling tracks of the first part of the race and then on the steep and technical slopes of the Aiguillette des Posettes, the main difficulty of the course, and then finish facing this incredible panorama of the Mont-Blanc range.
To participate to this race, it’s recommended to have a good mountain race experience, to be comfortable in any ground and to be autonomous for several hours. We draw your attention to the fact that a runner with no ITRA cotation higher than 350 points (check your odds) has very little chance to finish the race. In that case, it’s more recommended to participate in another race of Mont-Blanc Marathon.
Before to register, we strongly recommend that you read the route, profile and estimated passage times to be fully aware of the difficulty of this race. The barriers times indicated take into account possible slowdowns that you may encounter and we strongly advise you to plan your race with a margin over barriers time.

The organisation draws the attention of the riders to the fact that, according to the systems and the settings used, the gpx tracks may give very different results (from 2 407m to 3 192m of elevation gain).

After crossing the village of Montroc, you will take the path towards Tré le Champ, from there you will head for the Col des Montets.

After crossing the footbridge over the bism you will take a north path (a little cool in perspective …) towards Montroc, before crossing the hamlets of Frasserands and Tré-le-champ.

The time restrictions indicated below are given as an indication, they may be modified if necessary for the safety of the participants. In case of bad weather, and for security reasons, the organisation keeps the right to stop the event in progress or to change the time barriers. Any decision will be taken by the trail committee.
The arrival of a runner on a time bar outside the deadline implies his disqualification. The lower right corner of the bib will be “cut” by the postmaster and the runner will be invited to use public transport to return to Chamonix. If the runner wishes to continue the race, his bib number will be recovered by the postmaster and the runner will no longer be considered as a participant in the Mont-Blanc 42 km, so he will no longer be under the responsibility of the organiser.
Anyone who doesn’t respect the volunteers in charge of this function will be banned from racing permanently on all events of the Mont Blanc Marathon.
