Running thru pain

My foot pain has been diagnosed as plantar faciitis, basically an inflamation of the tendons connected to the heal caused by stress (running, in my case). Normally the cure is to take a few weeks off from running, but I don't have that kind of time. I rested/iced/medicated for a few days, then did a 12-mile test run on Saturday and had good results. Constant low-level pain, but it didn't get any worse as the miles went on. And the pain stopped the second I quit running. After two more days rest, I've run on it for four days now, with the pain being a little less each day (with more ice and ibuprofen after each run). It looks like I'll be able to salvage a run for race day. Not an ideal situation (nearly two weeks of missed training) but I'll start the race, and see how it goes.
