Wind gusts whipped across the summit ridge as you crossed the final switchbacks toward the Mt Baldy sign.You paused to take a breath, holding the two Nuun sticks against a backdrop of snow-speckled peaks — a snapshot of data and discipline merged in the thin air.
This was the third and final field test in the Register Ridge Electrolyte Series (Nuun vs LMNT vs ATH).By keeping conditions and route nearly identical, it isolated electrolyte composition as the key performance variable.Findings will inform TrailGenic’s adaptive hydration research and future Science Hub reports.
