Wha?

So then I had the spontaneous chance to run half a block today, and my stride seemed fine, or at least, much like it was before yesterday's hobbling. A few minutes later I again ran for a bit, and the stride still seemed OK.

Only difference I can maybe think of is that it wasn't as cold, and I had been walking around with my son.

Go figure. Not sure what is going on. But you can bet I plan to re-test tomorrow.
