I was planning to do a slow journey also, but again this wind.... the good part is that everything was so clear and perfect for pictures.
The statistical part was :72,93km in 5:08:24, Average 14,19km/h, Max Speed 47,04km/h, trip total 642,69km bike total 5998km
As for the audio and as Radio FM4 is from Austria and has FM coverage, this radio will be my main soundtrack as I love their diversity (spoken in English and German with news also in French), and of course by their music taste. This was the sound I listened once crossed the border: Oliver Koletzki feat. HVOB - Bones
