The pain will go away after a little while; I went through a few days at work with a few foam blocks between my posterior and the "ergonomically correct" chair at my desk.
Coffee: Where do you usually ride?
If you're in the Citrus Heights/Folsom area, I've found that the hills on Central make a great warmup, followed by a ride down Oak until it meets Auburn-Folsom. Turn right, then make another right on greenback and go up the hill that leads out of Folsom, into Citrus Heights. Gives a good workout to the quads, and the downhill on Auburn-Folsom can lead to some pretty amazing speeds. Watch for the cagers (as always).
