This mountainous route with almost 1000m of vertical drop will delight seasoned runners.

From the Prétairié parking lot, take the forest road towards Lac de Tavaneuse as far as the crossroads where you cross the stream to continue towards Tavaneuse. Take short strides up to the Chalets de Tavaneuse, from where a small flat area allows you to recuperate before climbing up to the lake of the same name. Enjoy the lake, then descend to the left towards the Col d'Entre Deux Pertuis, then the Pirons d'Ardens. Start the descent to Les Chalets d'Ardens. After 600 m, turn left onto the small zig-zagging downhill path, then follow the forest road to Cubourré. Take the left-hand path to Lac des Plagnes. Follow the forest road towards Le Cazot. At the La Séchère intersection, take the downhill path to Prétairié.
