Another suggestion for winter fitness: hiking. Not so easy in snow, but when there's no snow (as is usually the case here in NC), I found that I stayed pretty fit over the winter by taking long weekend hikes (lots of hills) in state parks with my DH. The scenery was gorgeous as well, and you stay much warmer than riding since you're going slow and generating lots of heat on the climbs. Some fitness is very sports-specific, so when I first got back on the bike after all the hiking, I still had work to do, but I gained "bike fitness" much more quickly than I expected.
I also ride on a trainer. I enjoy Spinervals some days, but others I just like to put on some hard-pumping music (XM satellite radio stations broadcast over out DirecTV connection - no ads) and jam. Sometimes the music motivates me more than Coach Troy, though his drills are good and very difficult. Of the Spinervals tapes I have (about 6), Uphill Grind is all women and quite a challenge!
Unfortunately, with the time change at the end of the month, it's going to be time to pull the trainer out again. I always dread that, but when it's quite chilly, I am glad not to have to ride outside. I just don't care for winter riding, at least on the roads. I might try some mountain biking on less frigid days, though!
