Well, the good news is that the past few runs have been irritation free. The bad news is that I am kind of fat and not in very good shape.
I am going to stick to my plan for fear of re-aggravating the injury and also because I need to get back into shape. I am building up my mileage now and will try for a 4k on Jan 27 and starting a training cycle on Jan 30th. Provided everything goes according to plan, of course.
