Recovery Race?

So I have been down without running...I have a serious hip/knee/leg issue on the right side and I have the Achilles thing on the left.  I went to the doctor and they told me no more running, they sound like a broken record.  I have not run for over 7 days at this point and plan on staying off of my feet until Thursday at least.  The biggest question right now is...can I use my upcoming race on Saturday as a "recovery race"?  I am running the Red River run in Alexandria, LA...barefoot...and am thinking that a nice easy 6 miles would be okay...slow without shoes and try to just take it easy and have fun...we'll see what happens on Thursday when I go for a quick 2 mile run...stay tuned...
