I agree, planning a tour in Eurovelo maps gives enthusiasm at first, but then you see relity is different.

However, the Euroroute R1 is not an abstract Eurovelo line. It's a real route, with real metal signs along the way. And the part I did was almost all along traffic-free routes, and it had also small wooden houses in stop areas [not so clean, in reality...] which you could use as a refuge!
