This fantastic trail running race in the Chamonix valley covers a distance of 50km and gives the athletes some of the most iconic and fantastic views of Mont Blanc and the valley.
Starting 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 50km and a total ascent of over 4000 metres.
Top athletes can complete this race in around 6.5 hours but for many it will mean a long day of running lasting between 10 and 13 hours.
If you don't want to take part then supporting the event and watching along the way can be just as fun!
