Proper electrolyte balance isn't a nice-to-have — it's the difference between hitting your splits and blowing up mid-race. When you sweat, you lose sodium, potassium, magnesium and chloride. Water alone doesn't replace them. That's why serious Hyrox athletes, endurance runners and functional fitness competitors build electrolytes into every training session and race-day plan.

Interval's Electrolyte+ is built specifically for the demands of high-intensity functional fitness. Whether you're grinding through a Hyrox double or deep into a long-course training block, it delivers the electrolyte profile your body actually needs — no sugar overload, no unnecessary fillers, just clean hydration support that keeps your muscles firing and your head clear.

Use it before training to prime your hydration, during long sessions to maintain performance, or post-workout to kickstart recovery. Pair it with Pre-Shot for a complete pre-race stack trusted by Hyrox athletes across the UK.
