Stage 12 of the 2027 Tour de France runs 162 km from Chambéry to Valence on Thursday, July 15, a flat day built for the sprinters after the Alps. ASO counts about 1,600 meters of climbing, none of it categorized.
The route leaves Chambéry through Saint-Laurent-du-Pont and Voiron, crosses the Isère by way of Tullins-Fures and Vinay, passes Roybon, at 541 meters its highest point, and Hauterives, and drops through Romans-sur-Isère into the Rhône valley. ProCyclingUK flags crosswind in the last 25 km as the risk.
Valence hosted sprint finishes in 2021, when Mark Cavendish won stage 10 from Albertville, and in 2025, when Jonathan Milan won stage 17 from Bollène.
Stage 13 is another flat day, and the Tour reaches Montpellier the next day.
