Haven't run since last Sunday...

I would normally be crawling out of my skin to run after not running for 2-3 days. Not running for 5 days is almost unheard of for me. In this case, after running a bunch of mileage last weekend, I don't want to jump back in the water too quickly for fear of injury (oh, did I mention that big, honking blister on my heel?!). I try to de-taper after a run the same way as I tapered. So, my next run will probably only be 3-4 miles. Does anyone do anything different than that after a race?
