Some winter days locally are so nice, you can see the light and the joy of getting out on a bike. 60* last Saturday. 50* and dry yesterday.
The winter triple means enjoying the hills at a slightly lower exertion level.
But it's damp & wet a lot, so I rotate bikes on the trainer. Views are the same.
One positive thing about indoor riding, you sure can work out the little niggles to find a perfect position. Or (for me), those little tweeks necessitated by an ungracefully aging body.
Reposition the brake levers, saddle tilt and/or height, etc.
