Nowhere to Boston in 12 Weeks

I'm registered for the Boston Marathon and it will happen April 16th whether I'm ready or not. The left knee still doesn't feel right, but after three weeks of easy running, at least it hasn't gotten worse. I'm down to buying new shoes. My work shoes were completely worn out, so I have a new sturdier pair (you have to walk a couple miles a day at the nuke plant). I ordered a pair of Saucony Mirage running shoes, hoping they're similar to the old Tangents. We'll see how it goes.
