I'm with Crankin'. Though I will usually ride most of the winter, this past year we switched gears and did a lot more x-country skiing. It was a nice break from the bike, and awesome cross training that translated in the spring. Around here, you can't go to a ski area without bumping into the same people you race bikes with during the season!

Of course, winter activities are always dependent on the weather. Last year was a good snow year for skiing, and bad for trying to stay on the bike outside. We have had years, though, where the opposite was true, and I logged a LOT of miles between January and March outside.

Catrin - if you are going to ride outside, winter shoes are the BEST investment. I have tried the Lakes, which are good, but discovered the Pearl Izumi winter shoes a couple of years ago and LOVE them. They keep your feet dry, and I rarely get cold feet with only one layer of socks.
