Walking a lot
I keep looking at my trainer in the basement, and then at the walking trails in the area, and the trails are winning.
Right now there is a sheet of snow and/or ice over just about everything, and the lows at night have been about 12F.
I have no desire at 68yo to break something skidding on the ice, nor do I enjoy it in any way. So, I have been walking 3-4 miles daily, starting at 6:30 am, seeing deer and coyotes and very much enjoying myself. I can walk fine without fear of falling, and I can walk in just about any kind of weather - snow, near blizzard, etc.
I don't mind riding down to about 40F with cleared streets or trails, but I just don't enjoy the snow riding and the ice riding.
To me it is about 2 things:
1. The exercise;
2. Relaxing and enjoying myself.
The trainer just does not satisfy the "enjoyment" criterion.
