hm. Very good point, pooks. I will have to contemplate that!

I'm sure a bunch of you engage in "pain calculations."

I generally spend all week obsessing about whether my knee's going to be painful enough to keep me from riding on the weekend (a certain amount of pain is acceptable, but if I can barely stand up w/o pain, it's not a great idea for me to be out on a bike). This past weekend, knee allowed me to ride Saturday, and I also rode Sunday and Monday (and Monday I was practicing hills for about a half hour and messed up my knee), so knee thinks it might need Saturday off. I am pissed. It is a Cindy training ride, and I need the practice, but I think it's too much climbing for my knee this weekend.
