Bike tour on a hot day, even on the summit of the Venn and the Eifel national Park. 65 km on unpaved ways. Several drink/water shopping on the way. Great landscapes. Wasn’t sure if I would make it to Cologne.
Warm with a breeze and mobile office on the back. Busy cycleways but empty roads. 102 km in Luxembourg, 11 km in France and 53 km in Germany. When I arrived home, I thought I could just repeat it.
