So I'm at Sesame Place in Langhorne, Pa., on Saturday. Sunny day, hot day and the fam is up on this net contraption. I'm getting ready to crawl through my second gauntlet of nets - Josh really wanted to do this - when I take a step toward it and with full force I knock my right kneecap into the side of the thing.

Pain. Pain. Pain.

Stiff for the rest of the day, I iced it Saturday night. Still, it was pretty sore throughout Sunday's five-miler. Then it was fine Monday when my workout was derailed by J's tonsilitis. Probably a good thing, because the last mile of this morning's run featured the steady throbbing of my knee.

You sign up for something like the Philadelphia Marathon, and the only thing you know for sure is that on Nov. 22, you'll be running it. You never know what's going to happen between points A and B that will make the journey easier, harder or a lot more painful.

But I'll grind through it; better that it happen now than six or seven weeks from now.
