The difference-maker
Why electrolytes are a game changer
When you sweat you don't just lose water — you lose sodium, potassium, magnesium and chloride. Those minerals carry the electrical signals that fire your muscles and keep your heart rate steady. As they drain away you get the classic mid-WOD wall: cramping, heavy legs, a racing heart and foggy focus — even when your fuel and your fitness are perfectly fine.
01Water alone dilutes what's left — replacing minerals keeps your muscles firing.
02Steady sodium means a steady pump and a clear head from run one to the final sprint.
03Less cramp, faster turnover between stations, and a stronger finish on the last 1 km.
When to take them — your Stage / WOD timeline
During · 45 min+
Sip steadily
Anything over ~45 minutes or heavy sweat: small sips between runs and stations. Don't chug — drip-feed it.
Right after
Rehydrate
A final serving to replace what you lost, alongside your protein, so the next session doesn't start in a hole.
Rule of thumb → if your kit is soaked or you can see salt on your skin, you're losing more than water. Add electrolytes.

Built with coaches.
Tested in competition.
We work with the athletes and coaches in the box to dial in what actually holds up on race day — at the start line and everywhere the timing matters. If it doesn't perform under a clock, it doesn't make the stack.
