New for 2025, this stage features the 13-kilometre climb of the Col de Penne (1040 m) from Aucelon, renowned among cyclists for its 600-metre elevation gain. Now open to WRC drivers, this narrow, winding route demands full concentration on both the ascent and descent towards Recoubeau-Jansac. Challenging terrain and weather risks, including frost-prone sections, make this a stage not to underestimate.
