I would of said get out today and ride but then the way it is raining down here, your window of opportunity has slammed shut.

I rode once in the rain on the road and not that far, and not that much rain. Way too much debris and water spray from cars and it wasn't even a busy road. I turned around and went home. It wasn't worth getting clobbered by a car or getting pitched over the handle bars while getting half way submerged in a giant, unavoidable, puddle.

Go to the gym and crank out some miles or just cross train (jog, elliptical) for an hour or so.

Better yet, do some flexibility to keep injuries away...
