French N roads should I or shouldn't I
I am off on my first tour in a couple iof weeks. I will be heading across the Pyrenees the east to west. I am in the process of working out my route and have noticed that my routes take me along N roads for most of the way, red on the maps. I was told to avoid these roads by someone as they are main national roads and very busy with heavy traffic. Has anyone ridden along the N116, N32 and N20 in that area and can they confirm this or advise alternatives please.
