My results are here. And in case you don't feel like clicking over there, here:
My feet were killing me after the race, but they're fine now. Now I just have tire legs - nothing unusual.
Analysing the splits, I see that I was speeding up through the Half, then I slowed down quite a bit. The second half took me 2:43:14. The splits are goofy after that, though the last 10K (20M to the end) can be compared to the first - 1:19:29 vs 59:11.
I ran a few more numbers, but I know when I hit the wall. It was about Mile 16. For almost an hour after that I just couldn't must any gumption. After Mile 24 I just decided I was going to keep moving at a pace that could be called a run until I finished.
