Cycling loop starting from Magnac-Bourg. This loop owes its name to the various major roads that it follows over short distances (D420 and D82) or that pass nearby such as the A20. It is a 17 km itinerary combining sunny and shady areas in the summer season. It is a touring cycle route in the heart of the Limousin, in a very natural setting. We can see several beautiful landscapes during this itinerary, and long railways.
