Marathon du Mont-Blanc - Chamonix-Mont-Blanc

The Mont-Blanc Marathon challenges runners with a demanding course through alpine landscapes, offering stunning panoramas. You'll traverse forests, plains, and mountains, with the snow-capped peaks of Mont Blanc always visible. Expect a significant physical and mental challenge, requiring semi-self-sufficiency. Whether you explore the Tête du Prapator, Le Petit Balcon Nord, or l’Aiguilette des Posettes, each path presents its own difficulties. The Kilomètre Vertical is known for being as splendid as it is steep.
