    I have to disagree with the Ben's electrolyte theory. I am a 45 year old ultra marathoner. No electrolyte or minimum electrolyte intake for me will produce severe leg cramping after about 20 miles into a run. I have tried to reduce the amount of salt I take and it always produces cramping. Once cramping starts It is hard to reverse completely and this hurts performance.

    • This can certainly happen if A) you have thyroid issues; B) you have a very low sodium diet; or C) you have not practiced gradually reducing electrolytes in training (vs. quitting cold turkey).

    Thanks Ben for the response. The only limit that I have had in distance running is the cramping issue. The only way that I have been able to manage it is through elecrolyte intake. I generally don't take any salt on runs 16 miles or less. I think that I could probably run a marathon without salt if I worked my way up to it. Anything over that, I don't think my body would allow me to go without salt and plenty of hydration.
