Gravel loop through the Haut-Languedoc

The ride

Roll out of Castres and the route soon follows the L'Agoût river, then the L'Aybes, before climbing into the Parc naturel régional du Haut-Languedoc. On the way back the Ruisseau de Roudil keeps you company. Of the 63.3 km, roughly half runs unpaved, with 995 m of climbing spread across the loop. You start and finish in Castres, so the rivers and the nature reserve bookend the day.
