cycling on snow didn't end well for me. SPD pedals unclipped in very steep descend, rear wheel jumped in the air, i landed upside down, heard a loud crack and bye bye collar-bone. Shit, i wanted to go to bicycle race before christmas...
My first words after crash were - Where the f**k are my sunglasses? And a lot of swearwords later. Well at least my bike, helmet and everything else except that f**king bone is ok... Even my sunglasses aren't broken. Good, that i'm insured.
