This fantastic trail running race in the Chamonix valley covers a distance of 54km (4,000m altitude gain) and offers runners some of the most iconic and fantastic views of Mont Blanc and the surrounding valley.

Trail des Aiguilles Rouges starts from the town of Chamonix, the route climbs high up into the Aiguille Rouges nature reserve, taking a different path each year. Not for the faint hearted (or unprepared) the race covers a distance of 54km and a total ascent of over 4,000 metres. Top athletes can complete this race in around six and a half hours, but for many it will mean a long day of running lasting between 10 to 13 hours.
