I love the winter! no bugs.
If it's above 5 degrees, I xc ski, snowshoe and run. If it's colder than that I tend to stick to the gym. I also ride my horse, but we have a heated indoor arena. My husband got a fat tire bike (Mukluk) last fall, and rode the mountian bike trails all winter. We would go out and showshoe the trails to give him a nice track, then he gets to ride them. He had a blast.
Late fall, winter, and early spring are the best times to ride, but the best time to run as well. Too hot to run in the summer at least at the speed (or lack thereof) that I run. Biking, thank goodness, lets me go fast enough to create a breeze of some sort. Of course, I don't have to worry about ice (or iced bridges) here in Florida.
Can't believe we are talking about winter already, it feels like summer just started.
I usually ride outside on the weekends until about mid-Nov and start up again in March. During the week I do spin classes 3x per week from about Oct-Mar.
Mostly because I don't have enough non-working daylight to ride.
I swim year round as well as run outside year round. In the winter on the weekends we x-c ski and hike.
I usually find that by doing the spinning classes and keeping active all winter I haven't really lost any fitness when I get back on the bike in the spring.
This year, for the first time, I plan to ride. It's been such a hot summer, I can't wait for it to be cooler. I have an indoor trainer I plan to use if the weather is too bad. I hope to start out next season with a good base of fitness and see where that will take me.
