Last week, Hugo Parmentier and I completed our Mega-circuit project, one of our biggest projects of this year so far: sending 100 different 7A boulder in Fontainebleau in a day linking them by fair means (biking or running), a huge circuit in the whole forest starting north in Rocher Canon and finishing south in Nemours.

This was such an incredible day and intense experience!

The idea is born from a discussion between roommates and was fed by the experience of our Font locals friends.

Initially, to celebrate the 70th anniversary of the first 7A of Fontainebleau, aka “La Joker”, we wanted to complete “only” 70x7a, keeping some bonus in case we would be fast enough to climb some more…

After a month and a half of discussion, setting our ethic, our itinerary and the best boulders among the thousands blocks in the forest, we woke up with the early lights on the 14th of May to give a try to our Mega-Circuit.

The idea was to climb only during the daylight as it is forbidden to climb at night in the forest. From waking up at 4h30, starting climbing at 5h30 to finally reaching home at midnight, we biked (70 km), climbed and ran our way through the deepest and most well known parts of the legendary forest of Fontainebleau. Climbing our selection of the most delicate, stunning and classic boulders of the 7a/+ range. In the middle of the day as things were going good and as we were in advance in our schedule, we decided to go hard and add the bonus boulders we had in our list to reach the 100!


We laughed, screamed, sweated (a lot), struggled and shared an ultra intense journey. A week later, we are still struggling with fatigue and skin...

We hope this “multipich” sort of adventure will give ideas to other climbers to try their own low-CO2-emission projects (close to home).

The whole day and every boulder we climbed were filmed by an amazing crew. A film will be produced by Mountains on stage and directed by Jérôme Tanon. All the filming and extra shots were made using fair means as well. Stay tuned, a whole film about this adventure will come!

Thanks to all the people involved in the project: Soline and Tess, the Mountains on stage and shooting crew, our sponsors and partners of the project, Nicolas for his amazing and personalized “Boolder app”, our locals friends for the boulders/itinerary ideas, Bleaumeteo for the annual forecast of the forest. Special thanks to Jerome and Cyril, Elise, Zoé and Hélène who followed us all day long by bike to get some sick shots of the project.
