    The famous and mythical GR 20 from South to North – from Conca to Calenzana – with a lightweight backpack!

    During the course, we will enjoy the scenery of this “mountain in the sea”. Passages in the forest, a hundred peaks over 2000 m, block routes, a technical group to make of this route an exceptional playground.

    Two experienced guides will supervise you. We have a perfect knowledge of the terrain and will assist the group during the stay.

    Since your travel bags will be transported from stage to stage, you will only need to carry your equipment for the day. An important asset to enjoy the maximum you can and put the odds on your side.

    This tour is for experienced trail runners, used to technical fields and mountains.

    There are several reasons why this trail running is fantastic:
    – A mythical course with demanding and beautiful steps
    – A transfer of the travel bags and daily assistance for light running
    – 7 steps from the South towards the North for a balanced course
    – The ideal preparation for the UTMB due to its distance or the Diagonale des Fous due its technicality
    – Professional advice on how to best prepare the course
    – Logistics: transfers, assistance, baggage transportation, accommodation, meals.

    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 7 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.

    Are you interested in this beautiful adventure on the GR 20? Then I invite you to contact me. We will have the opportunity to discuss the details, your level and your desires… It will be a pleasure for me to be your guide and coach during these 7 days! And if you want to practice trail running on traces of the UTMB, have a look at this trip!
