Well, I did it. I did not improve my time today. But at least I finished this crawl. For me, and for a lot of others, it was not so much a race as a test of endurance in the heat and humidity.
I couldn't quit early, though I was tempted to several times, because Caleb told me as I was starting out, "If you finish this race today, I'll be so proud of you."
And so I finished it.I'll post more photos later.
