    This ultra trail running course around Mont Blanc takes up traces of the legendary event in the world calendar of trail running in Chamonix. 

    We’ll move along the breathtaking sceneries. In fact, it’s the opportunity to get into the key aspects of a good physical and mental preparation in this legendary trail. Or it can simply be to discover this mythical and sportive tour.

    Beyond the sporting aspect, this trip allows us to discover the magnificent sceneries of the Mont Blanc massif. Indeed, we get to experience the culture through 3 countries: France, Italy and Switzerland.

    This course is also an opportunity to discuss the essential aspects of a good physical and mental preparation: training, nutrition, equipment, techniques…

    This course is unique because:
    – It has a high level of trail coaching;
    – It’s a legendary trail with incredible sceneries;
    – Stages are accessible and balanced to take the time to discover and enjoy the itinerary.

    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 20-35km a day and go up from 1000 to 2000 meters. We will mainly be on single tracks and varied terrain. We will partially be on aerial paths.

    Did you find this trip interesting? Then I invite you to contact me for more information! I will be happy to guide you on these paths and coach you throughout these 6 days. If you are looking for something different, we’ll have the opportunity to discuss together other courses. I have many options in the Alps and surroundings, for all levels. For example, you might enjoy some intense Trail running training in Annecy.
