I bring my bike to work with me everyday anyway so no changes in that plan. (I drive a Tahoe and keep the bike with me 24/7) However, once the days start getting really short, I have a route mapped out from my work that I ride. I just change clothes as soon as I get off work and go hop on the bike right away. I can still get in a good 20 miles up until late in the fall almost early winter. After that I use the trainer (which I hate BTW) until about mid February when I can start getting in some real rides again right after work. Usually in Feb/Mar I'm pushing to get in 12/13 miles but hey, at least I'm on the bike.
