Simply brutal the rise! If only over 2km from Waldzell from 200HM increase, so uncomfortable! Single-lane road with large trucks and Polish small trucks (GPS controlled?) so that you can only drive up narrowly at the roadside and no individual serpentines for relief. With full luggage but hard! Once I parked my bike next to the tarmac and myself next to it for a short rest. Because of oncoming traffic, cars would have to slow down and be considerate of each other. A driver showed me the bird! Dodging into the field would have been too much for me!
