Where do your routes go Ivo?
Mainly Ardennes and Eiffel, so quite scenic routes.
200 a big loop around the German city of Aachen, first 100 quite lumpy, 2nd 100 fairly flat towards and through the Maas-valley. I'm currently retracing the last 50k to evade areas prone to flooding.
300 Maastricht-Bastogne-Huy-Maastricht, do I have to say more
400 (new route) night section through the Maas valley, early morning through the Semois valley to the city of Bouillon. Return through the Ardennes.
600 is not usable as a permanent since it follows the Mosel valley and thus doesn't work via the AUk system without adding an enormous amount of info-controls.
