Randonnée VTT La Milliacoise

La Milliacoise is an annual MTB and gravel randonnée organised by the Club Cycliste de la Vallée de l'École, with the start and finish in Oncy-sur-École near Milly-la-Forêt. The event offers multiple route lengths, from short family loops to long-distance circuits of around 100 km, mainly through the Trois Pignons forest in the Essonne. Routes mix sandy singletrack, forest paths and gravel sections typical of the Fontainebleau massif.
