  • An official and full tour of the Mt Blanc ultra trail running race

  • Personalized advice to prepare better for the race

  • Comfortable accommodation


This trip around Mont Blanc takes traces of the legendary ultra trail running race in the world trail calendar (168 km and 10000 meters of altitude change). You will progress in breathtaking landscapes in the company of an experienced trail running leader. We will cover many topics, for example: recognition of the path, advice on physical preparation and nutrition, equipment advice, technical improvement…

The opportunity to take care of key aspects of a good physical and mental preparation for this legendary ultra trail. The trip is for runners with ample experience. In addition, you must have already participated in long trails or steps (a race book is required upon registration).

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

During these 4 days we will run on average 35km a day and go up from 1500 to 2500 meters. We will mainly be on single tracks and technical trails (stone, névé…). We will partially run off trails and be on aerial paths.

Does this trail running training around Mont Blanc sound interesting? Then please don’t hesitate to contact me! We will have the opportunity to discuss your level.

If this course is not appropriate, we will talk about all the others trips that I organize this year in the Alps and elsewhere, for beginners and experienced trail runners. If you are looking for a longer trip here, I also offer this Ultra Trail race trail training in 7 days.
