FATMAP difficulty grade
This race takes place in the form of a time trial. Be careful, it's an alpine race! The end of the course is an aerial via ferrata (not recommended for people with vertigo) with steps, cables, pedals, handrails...
with a finish at 2000m. Poles are not allowed because of the technical nature of the end of the course. A bonus for the record time will be given to the 1st man and the 1st woman of the KM Vertical. https://www.marathonmontblanc.fr/fr/les-courses/km-vertical-du-mont-blanc/
