I climbed it from its easier side, the one that starts from Foix and stretches for 28 kms, crossing the Col de Marrous. It's a steady climb, with a few tough kilometers, and very pleasant. It's the side used by the Tour de France to descend it. The best thing about the Mur de Peguère are the views from its summit.

I can only speak about my experience descending it from the south side, the one that starts in the village of Biert. It's simply a great pass, with a very tough final section, very similar to its close brother Mur de Peguère. With hardly any traffic, it has the appeal that the road is very narrow and very winding, which helps mentally.

Be careful, since yesterday, June 19th, the descent to Rivèrenert has been freshly graveled and dangerous. I had a rear puncture due to small, sharp gravel sticking to the tire when braking. So, don't go crazy on this descent, friends.

Because around 12pm and >31°C, the climb from Biert is mostly in the shade, and this pass generally ends a series of small linked passes (like Portech, Catchaudégué or La Core, Saraillé, etc.). And the challenge of the last 3 km is worth experiencing to strengthen your mental strength. Get to your pedals

This is the longest tunnel on the greenway: it's super fun to go through. Be careful: it's a bit chilly!

A very beautiful viaduct, it's a bit impressive and truly unusual on a greenway. The train used to go there, now the bikes go there!
