13,5 km each way, and as of this winter I try to commute every day, year-round.
That is, I try not to wimp out because of the weather or light conditions, only if I have to transport something large, or if I'm going to a party or suchlike after work...
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
