One of the things that helps me is to tell people that in the winter I can burn 800 - 1000 calories a day by riding my bike to work. It's extra effective if people happen to be munching on holiday treats at the time.
The other thing that helps me is to accept the fact that riding my bike this time of year is well outside the norm of typical behavior for this part of the world, and that people will naturally make comments and ask questions. In fact if I'm being honest with myself, there's a lot of days where fanaticism plays a role in getting me on that bike in the morning.
While I wouldn't say you're crazy, there are a lot of pretty die hard commuters who put the bike away once the snow flies.
