Marathon Training!!!!!!!!

I have about two months till the marathon. I've been training pretty hard. I just got back from 16 miler. Ouch!!!!!!!!!!!!!!! I was fine for the first 11 or so miles, then mile 12 started hurting. I started getting pain in my thighs, shins, and ankles. That pain lasted until about mile 14 or so, then the pain turned up a few notches. I wanted to give up an quit.... but i kept up an finished in 2:26:16, which i'm very happy with, that comes out to a 9:15 miles. I hope I can run that pace for the marathon, but I don't know. I was in a lot of pain and wanted to give up those last few miles, Oh well, we'll see how it goes.
