Course change for the 80km

The security commission met on June 14th to approve the feasibility of the different Mont-Blanc Marathon courses.

After many on-site visits, it was concluded that there was a significant amount of snow above 2200m in altitude and that many snow fields were still present between 1900m-2200m. Furthermore, many trails had deteriorated after the erratic springtime weather conditions.
The trail maintenance crew of the municipality of communes from the Chamonix Mont-Blanc valley are working hard to guarantee the best course conditions for runners.

It is agreed that the course for the 10km, 23km, and 42km races will remain intact.

As for the Mont-Blanc 80km race, with its 6000m vertical gain,
the course does pass through various altitude sectors hence the safety commission has already initiated the first security measures.

The Col de la Terasse (2648m) is under snow from Loriaz (2020m). For ethical reasons the safety commission did not wish to secure this area with hundreds of meters of safety nets that would transform the mountains into a 'stadium'. The ideology to protect the environment is a strong priority and value for our races.
It has therefore been decided not to cross this mountain pass and reach the Emosson dam (1920m) by re-descending the Loriaz towards Vallorcine and then climbing up to col du Passet.

At the end of the course access to the plan d'Aiguille refuge (2233m) is deemed too dangerous due to the many sloping snow fields, especially considering that runners will be passing through this section at night. It is therefore planned that runners descend to Chamonix and pass by the Blatiere pastures.

On Monday June 20th the commission will have another meeting to examine and validate other sensitive sectors of the race: access to Brevent (2525m), la Tete au Vent (2110m), la tete de l'Arolette (2333m) and the Montenvers/Blatiere traverse (2100m).
