How tired am I? See my pathetic, sympathy-seeking thread in the Newbie forum. Heck, I got exhausted just reading li10up's workout schedule.

Seriously, though, some days I react the same way (just want to flop down on the couch and stay there forever) and other days I have lots of energy leftover after a ride. I haven't yet figured out the why's of that, though; it seems quite random.
