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.

It is a MUST of the Pyrenees, without a doubt, that should be included in any route that crosses the Pyrenees from side to side. Any of its slopes 2 is spectacular and tough. The views from its summit are wonderful, feeling the wild side of the Pyrenees. Of course, once at the summit of this pass... you have to descend to the Étang de Lers and enjoy a quiet rest on the shores of the lake. It is a pass that has been part of the Tour de France route on several occasions, although always far from the finish line. The first professional rider to crest it in the lead was the unforgettable Marco Pantani in 1995.

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.

I liked the climb from the north side (from Massat), very scenic and alpine landscapes towards the end at the étang de Lers

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
