Stage 15: Millau to Carcassonne. 181km.

Passing under the impressive Millau Viaduct (the tallest bridge in Europe when it was opened in 2004), today’s stage throws up some amazing geological features. We’ll get gorges, caves, cliff faces and green, green plateaux and pastures in between. It also features the Tour’s first ever ascent of the Pic de Nore – relatively gentle gradients, but topping out at 1,211m – before rolling down towards the flatter lands of the wine-growing region of Languedoc-Roussillon and our destination Carcassonne, a fully restored and breath-taking medieval city.
