Two things at play contributing to cramping. Dehydration and electrolyte depletion. The muscles switch to an "on" condition and can't shut off. Pickle juice contains lots of salt which is composed of two necessary electolytes; sodium and chloride (NaCl). Drinking the pickle juice will help. But, it does not contain other necessary electolytes; magnesium and potassium. Also, loading with salt causes hypertension and other health issues as well as ironically, dehydration. So, balance. Hydrate every day. Supplement day of event with logical amounts of electrolytes and water.
