So, electrolyte balancing is always a fun topic. My friend, Lauri, asked me on Facebook after my DNF at P2P what happened. I gave here the raw, simplified answer. Andy Reed, who ended up taking 5th at P2P, chimed in that my cramping was due to fatigue and that I had too much salt in my body (as indicated by the salt on my clothes). I disagree.
I'm always open to all points of view on stuff like this and would love to hear others' opinions on it, expert or not.
