At the school, there is a tap on an outbuilding. When heading towards Foix, this is the last tap directly on the cycle path that we noticed. It makes sense to refill your supplies here.

One of many old train stations on the route, all of which are inhabited as private homes. How we wished that one of them housed a café. Nostalgic memories of the Alpe-Adria journey are awakened!

The Lac de Mondély is a picturesque reservoir in the French department of Ariège, about 10 km from Mas-d'Azil. With its emerald green color and wooded shores, it is a popular destination for walks, picnics, and nature observation. A circular trail about 8 km long leads around the lake and is well-suited for a leisurely hike. Fishing is permitted (with a valid fishing license). However, swimming has been prohibited since 2023. There are parking spaces on site and a snack bar during the season.

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
