I haven't ridden because I don't have the layers for it. I have everything for the upper body, but I don't have any cold weather pants or socks. And I am not about to invest in it just yet. Maybe in the future I will but for now I am good, haven't really put too much weight back on, and I do get exercise by shoveling my street clean every time it snows! I usually clear about 20 parking spots alone.
But I am getting cabin fever and I haven't stuck my road bike in the trainer yet, mainly because the trainer is an older design that won't work with QR skewers. Guess I could chuck my MTB/commuter in there.....but then I couldn't ride outside if I wanted to.
