After a departure from the Plastics Valley from the Espace Loisirs d’Arbent (01), the circuit starts with a climb towards the “hautes-combes” of the Jura. The Haut-Jura, ideal territory for the practice of the bicycle with its splendid combes, its forests, its lakes and its picturesque villages. The journey continues in the Jura mountains towards Lamoura, the historic village of the TransJurassienne, a long-distance cross-country skiing event. We will then join the small mountain of Moirans-en-Montagne, capital of the toy industry. The cyclo route goes through the emerald land, surrounded by lakes, mountains and rivers that are a delight for cyclosportifs. The ascent ends at the edge of the Vouglans Lake on the nautical base of Bellecin, a real seaside resort and a preparation center for sportsmen and professional teams like the French rowing team.
