The reason why I am sharing this story with you is that I broke the number one golden rule. We take care of ourselves first, then we help another. During the final 1.20 miles I was barely hydrating myself.
No, your main error was that you were pushing forward when, because of your conditions, you should have already turned back.
How do you know that you were dehydrated?
What was the color of your hydration indicator?
Going 1.2 miles without hydration is OK.
Anyway, dehydration is overrated (e.g. see Waterlogged by Timothy Noakes).
