Frequently Asked Questions
Do I need high-sodium sticks for runs under an hour?
For most runners, plain water is sufficient for runs under ~60 minutes. High-sodium sticks are most useful for long runs, hot conditions, heavy sweaters or when you want to prevent cramps — otherwise a low-sugar, mild-electrolyte stick is fine.
Will zero-sugar sticks cause stomach trouble while running?
Zero-sugar sticks are generally gentler on the stomach than sugary sports drinks. However, some runners are sensitive to certain sweeteners (like stevia) or concentrated flavors — try a short run first to confirm tolerance before race day.
How should I carry sticks during a run?
Most single-serve sticks fit standard shorts pockets, handheld bottles with a sleeve, or small running belts. Pack them in a zip bag if you sweat heavily or store multiple sticks in a compact sachet to protect packaging.
