New Electrolyte Supplementation Policy

The Hardrock 100 Endurance Run does not supply electrolyte supplement capsules, tabs or powders for runners or pacers. There is no clear data to support the use of salt supplementation in ultra endurance events.

Overhydration is major issue in distance exercise. Salt supplementation has not been proven to lessen the risk.

A drink to thirst strategy is recommended during Hardrock.

Hardrock aid stations will have a variety of salty foods.

Tailwind will be available as a pre-mixed electrolyte and calorie replacement drink.
