    Three days of trail to practice in the area of the Mont Blanc marathon and to share information about preparing for this circuit. Indeed, it’s now unavoidable on the international calendar of mountaineering runners. In order to be closer to the information, you will be received at the Maison des Sports Chamonix by the staff organization of the race. It is the opportunity to receive the best advices and details of the tour!

    You will stay in a familiar hotel 3*. The setting is exceptional in the heart of a large park opposite to the Mont Blanc and the Bossons glacier. Besides, the menus are planned according to specifications for the practice in the track. In addition, you will have a spa and sauna available for optimal recovery!

    In the ‘extra’ section below, you’ll find information about the required trail running level you need to have. You will also see the equipment that you need to bring with you.

    During these 3 days we will run on average 20-35km a day and go up from 1000 to 2000 meters. We will mainly be on single tracks and technical trails terrain. We will partially be on aerial paths.

    Is the Marathon du Mont Blanc in the list of the next races you want to run? Then please contact me! I would love to introduce you to its beautiful trails and share with you my extensive mountain experience. If this program does not match your wishes, your level… I can bring in other courses I organize so you can choose the one that best suits your needs. In the Mont Blanc area I also have this 80km trail and the UTMB training.

    What People are Saying about Caroline Freslon

    Great experience, but definitely favored toward elite runners. One of our guides, JC, was amazing. He cared about every runner. The other guide seemed only to care for the elites (and himself). On top of Col des Montets, I asked if we had time to put on warm layers. The guide said \"of course,\" but then quickly proceeded to run off with the entire group while I stood bare and freezing with my gear unpacked. Total lack of consideration for the well-being of his runners. Otherwise a great tour.
