A revised version of the 2019 Valdrôme / Sigottier stage, this fast-paced test now starts in La Bâtie-des-Fonds, France's smallest village (population: 2) and source of the Drôme river. The route begins with narrow, winding roads to the Col de Carabes (1261 m), marking the natural border between Drôme and Hautes-Alpes. A technical descent to La Piarre follows, leading into a rapid final 8-kilometre stretch to Aspremont.
