So...having spent a few minutes doing some research on this, my cramping may have had to do more with muscle fatigue than my electrolyte content. I found a good online article discussing this that will give me food for thought for future training as well. Unfortunately it's hard for us to replicate the altitude impact on our local bridges.
Here's the link to the article: http://www.irunfar.com/2013/07/cramping-my-style.html

The heat affected me as well, and I am used to it as I come from South Florida. I run with EFS which is a carb and high electrolyte beverage. I set a timer to drink often but I started cramping in my quad and foot after 3 hrs and could not work it out. I got cleared to go ahead at the A frame aide station but did not make it to the A frame chip timer in time so had to go back down. After Barr Camp on the way up I had to keep stopping to try to stretch out my quad so I knew I would not be able to make it to the top anyways in that condition. If I attempt to do this again, I'll have to do something to address the cramping in addition to my beverage. I did not bring enduralites because I thought my drink would be enough, but I learned that lesson the hard way. I did eat salty snacks on the way but that wasn't enough either. It was funny how everything, including my hammer gels, stuck to the roof of my mouth. That was a new experience.
Despite this...I'm really proud of how far I got on my first attempt. The volunteers were awesome and so friendly. I'm amazed at how the city got cleaned up so fast. We're a little used to damage from hurricanes, and we never get cleaned up that fast. Congrats to everyone.
