"My half marathon was AMAZING! 7-minute PR! The fuel was great. Everything just clicked. Big confidence boost and I feel ready to get back to my training tomorrow. I’m happy! My experience has been wonderful. I also love the fact I don’t feel lightheaded after running. I know 100% of that is from fueling properly."

“Hydrating to maximize blood volume is essential for thermoregulation, maintaining cardiac output, and supporting gut comfort. Optimizing sodium intake for hydration is critical.”
