In 1987, Skibby rode solo at the head of the race, when he reached Koppenberg. He had an advantage of two minutes, but climbing the hill he became slower and slower and the peloton came closer.
The car of the race commissaire followed Skibby so close, that when they wanted to move away, the car knocked Skibby, who fell to the ground. The car run over his back wheel and narrowingly missed his legs. Skibby’s race was over.
