I hope your do-over is a huge success.

I will not do another full unless I can figure out what is going on with my back. Nothing is worth going through that again. I tried sitting down at the W tent after the marathon and it was so bad I couldn't sit until I hobbled back to the massage tent and let them "unlock" it.
After that I was fine. I got up and ran a mile the next morning and Mike and I went to the water park and went up and down all the stairs. I agree, I don't have anything to prove to anyone else, just myself. This was not about the temps for me that day--I finished with too much energy left. Honestly, unless the doctor/pt can help me figure out what is going on, I think I am done with long distance (longer than a 10k) running. I ran 9 miles on Saturday and I have been miserable all week. It's just not worth it anymore--to go through all that training and have a miserable experience and a miserable race.
