that sucks. especially when you're worn out already.
one time i was on a group ride in an area i didn't know. i wasn't in good enough shape and was in danger of being dropped. i saw riders way off in the distance and i had to struggle to keep them in view. all i wanted to do was stop and lay in the grass, but i knew if i lost them, then i'd be screwed as i had no idea how to get back myself. so, i was worn out, cramping up, pissed that they dropped me, and worried that i'd be stuck out there. pretty ****ty ride actually.
