The Koppenberg has been dropped some years because it was deemed too difficult and too dangerous. Particularly when wet weather had made the cobbles slippery, it was hard for riders to take the steep slopes all the way riding. One rider falling could bring many others down and, in turn, halt those behind, who often had to shoulder their bikes and run up the remainder of the hill. In 1984 only two riders - Phil Anderson and Jan Raas - got to the top on their bikes. In 1987 Danish rider Jesper Skibby slipped and fell on the slick cobbles, before being run over by an official's car who tried to pass him. The climb was subsequently banned from the Tour of Flanders for the next 15 years.
