Back to square one?

I ran on Sunday and couldn't walk without a limp Monday. Ugh. The current plan is to pool run or elliptical until the end of Sept (or until I get impatient again). If I do an hour of exercise a day and keep my weight down for the next two weeks, and I'm all better on 1 October, I think two months of running will be enough to take a crack at the Jingle All the Way 10k in early/mid-Dec.
