How we calculate this

Sweat rate

  • Light: ~0.4L/hr. Moderate: ~0.8L/hr. Intense: ~1.5L/hr.
  • Sweating level multiplier: low ×0.7, medium ×1.0, heavy ×1.4.
  • Heat uplift: at 25°C to 30°C ×1.15, above 30°C ×1.30.
  • Weight scaling: sweat rate adjusted by bodyweight / 70kg.

Electrolyte content of sweat

  • Sodium: around 900mg per litre of sweat.
  • Potassium: around 200mg per litre of sweat.

One sachet replenishes

  • Sodium 195mg. Potassium 300mg.
  • You might need more than one sachet on very long or very sweaty sessions.
Sweat sodium ranges widely across individuals from ~400mg to 1500mg per litre. 900mg used as a usable average. Method follows WHO oral rehydration solution standards. Sources available on request.
