This west loop is slightly harder than its neighbor with more single tracks and a downhill which will require good technical mastery after Montcléra. The reward is in the varied landscapes and terrains you will discover. This circuit joins the Cazals Quercy Outdoor base on its northern part which allows you, if you wish to extend the ride, to access circuits n°5 and n°6 to reach up to 60 or 75 kilometers in total.
