On Friday, we (Marie-Luise, Samuel and me) started from Landshut down the river Isar. Cycling down a river is rather nice. First of all it can be really beautiful, downhill (most of the time) and last but not least you always find your way. No more searching for the right directions because it is clear.
On this day, we made 130km from Landshut to Passau more or less on flat roads with one small exception. The Youth Hostel in Passau is located in the castle on top of the hill and the road leading to it has a 22% gradient. A real killer after a long day of cycling.
