ridus interruptus

Last night, one of my least favorite cycling related things happened(other than crashing). The infamous Ridus Interruptus. This time it was due to compatability issues btw the Garmin and the Pwrtap. By the time I got it sorted, priorities shifted to child 1.0 and his homework.

Why am I always so grumpy when the ride doesn't happen or gets cut short? Is it because I'm mentally in "attack mode" ready to push thru the pain, only to be dropped back into normal interpersonal realtionships?

Is it testosterone related?

All I know is that I turn into a testy bitch, that even I don't like.

Lucky for me, I only had to wait a few hours for the furly run to get all that angst out. 6 miles or so @ 5 am seems to leave me drained and ready to deal with people. The post run coffee and pancakes(thx Z) didn't hurt either.
Now I just have to stay awake thru work....always a challenge.
