Final miles

I ran my final training miles tonight - 2.3 miles without even leaving my neighborhood - before the Dallas marathon on Sunday. I really took it slow, averaging 10:24.
I've been looking all week for my rubber heel cups, which I want to wear during the race to help prevent soreness in the bottom of my left foot. I never could turn them up, so before my run tonight I made my own out of an unused pair of running shoe inserts. They aren't quite as comfortable as the real thing, but they're not bad. I might change my mind about wearing them, but at least I'll have them if I want to use them.
I've pretty much decided my only goal for this race is to finish. If being under-trained is better than over-trained, then I definitely have that edge. Because of the torn tendon in the bottom of my left foot, I missed my last long run of 20 miles and about two weeks of running beginning about Nov. 1.
I think I'll have to take it pretty easy, especially early, if I'm going to make it to the finish line without pulling up lame. I was thinking the other day that I might run the first 6 or 7 miles at a 10 min. pace, then the middle 13 at 9, and the last 6 or so at whatever pace I can muster. In theory, that might result in about a 9:30 pace, or a 4:09 marathon. Anything around that time would be fantastic.
