From Giroussens you roll out for a 77.6 km loop, all of it paved. The route follows the L'Agoût, passes the castle of Mézens, then the Hôtel de Rolland and the castle of Saint-Géry. Later you meet the Tarn and the Dadou rivers, with the castle of Lézignac along the way, before turning back to Giroussens.
