Old skool....Liege-Bastogne-Leige...1980:

"They weren't, but they soon were because snow dropped from the sky just before the turn. It fell from the sky so fast that within minutes there was nothing to see but a white road, white air. A Dutch rider called Gerard Keulers broke away and stayed away for 100 kilometres solely because he thought he'd stay warmer that way. Behind him, 50 riders climbed off. The giant Frenchman, Gérard Saint, stopped to pee on his hands to bring them back to life."
