WELL, I DID IT!!
I finished the mini-marathon. I can tell you my knees did not like it. Not one bit. But, regardless, I crossed the finish line in a blistering 3:57:34. (By contrast, my son finished in 2:20:18. but he's a show off.) I finished an eye opening 27,344th. (Yeah, really.)
While walking around the Indy track, I was passed by a guy with a prosthetic leg and a heavy set middle aged woman wearing flip-flops. On the west 10th Street leg, around mile 10 of the course, a local bar gave out small cups of beer. I passed, but my son had three. He said it was the greatest run he's ever done (and the best beer he ever drank.)
It was a good day. My knees will ultimately forgive me (I hope.) Woo-hoo!
