A big flaw in my pre-post-season thinking is that riding will continue to be pleasant. It's not. Riding in mid-40's temps is miserable. Clothing is binding. Anything exposed is frozen. Snot happens. Eyes water and fog up glasses. You never know exactly how many layers to put on so you spend the first 20 minutes opening or closing zippers, bouncing between too hot and too cold. Winter riding sucks.
I got 15 miles at an average 19mph today. Not a bad workout. But not fun.
