How to use it in a race
Dose by sweat rate, not by the packet. Heavy sweaters in heat may need 500 to 1000 mg of sodium per hour, which at 345 mg per serving is 2 servings an hour as a middle estimate.
Take it with water, and take it on a schedule from the first hour rather than waiting for cramps or a headache. Sodium has no effect on cramping, but it does keep you drinking and keeps plasma volume up.
Servings per hour assume the 0 g per serving on the label. The finder sets your own g/hr target from race distance, sweat and gut.
