Finally. Recently it's been either appointments immediately after work with the trainer and too dark (also: too sore) to ride home afterward, or too cold and I don't have the right clothes. I need better gloves to ride when it's under 25. I have a face mask, I have fleece pants. I just need gloves.
Anyway, I rode. Definitely my legs are stronger, if not the pistons of my youth. I rode 2-7 (is there a technical way to enumerate gears?) wherever it was flat (up from 2-5), and 2-5 instead of 2-3 or -4 wherever there was slight incline.
(And there is slight incline, despite Denver's overall flatness. From my house to work is upstream. Not that the slight incline is enough of a hill really to justify the lower gears.)
I expected, going home, to be 3-x all the way, but I didn't count on a strong biting wind. Still, I rode.
