Sorry to hear this was a bad race for you.

Don't let it discourage you to much, just gives you something to go back and reclaim next year.

Out of curiosity did you take any pain meds or anti-inflammatories before the race started?

I noticed this season that I cannot take ibuprofen before I run otherwise I end up with stomach cramping pretty badly. At first I thought it was a fueling issue, but it turned out to be that. Might be something to consider. *shrug*

I too applaud you for all the races you do. Keep it up! You are an inspiration.
