Two-days-later-update: I'm not even in pain. A sore saddle at the end that went away in a few hours and a little stiffness in the leg the next day.
I'm still buzzed, too.
Um, but yeah... this is a huge motivator. I am realizing that I can do impressive cycling feats and that's exciting to me. And it's *fun* doing this in ways that going to the gym is just plain NOT. I can do this. Already plotting how I'm going to do the 100mi ride.
, your route did have more climb than mine did. I had 1400 ft up, 1400 ft down, and then it was mostly level terrain after that.
