    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.

    Pour moi le trail c\'est avant tout la découverte de nouveaux territoires, les rencontres et les échanges avec d\'autres passionnés, le respect de la nature. Mes 3 stages avec Caroline m\'ont permis de retrouver ces fondamentaux dans un cadre toujours bon enfant, mais pas moins professionnel. Caroline est une passionnée de montagne et de tout ce qui y touche (sport, culture, gastronomie) et elle sait comme personne transmettre sa passion et ses bons conseils, toujours avec le sourire. Je garde un excellent souvenir des rencontres avec les autres stagiaires et mais aussi avec les autres encadrants, Guillaume, Seb, Cédric, Lydie et tant d\'autres rencontrés au cours de ces stages.

    J\'ai fait deux stages avec Caro, c\'est devenu une amie, et chacun de ces stages m\'a laissé des souvenirs inoubliables. Le premier stage en 2014 en Haute Savoie à l\'occasion du Trail du Gypaète. Le Deuxième stage en 2015, dans les Calanques de Marseille. Ces stages auront été parfaits à tous les niveaux: Paysages grandioses (on sent qu\'ils ont été choisis avec soin), des échanges techniques avec des \"pros\" (un grand moment quand Caro inspecte les sacs à dos...), pleins de conseils nutrition - mode de vie etc... La découverte des autres stagiaires mais aussi des autres encadrants (très bon contact avec Guillaume Lenormand par ex.). Des conditions matérielles top (hébergement, repas, organisation etc...). Seule critique: le temps passe trop vite, c\'est toujours trop court! Donc au final quand c\'est fini, on n\'a qu\'une envie... c\'est de repartir pour un autre stage! Et vu le nombre de personnes que l\'on croise sur les stages qui en sont à leur n-ième participation, je peux affirmer que ce sentiment est partagé!
