The calculation is a general estimate based on type of training, duration, body weight, intensity, temperature, and weather conditions. Fluid and sodium loss are shown as ranges because sweating rate and sodium concentration in sweat vary greatly between individuals. The recommended intake per hour is deliberately lower than the total loss, for safety reasons — but the number of sachets is always based on the entire estimated sodium loss for the duration of the session, not the more conservative hourly intake, so that the need is not underestimated. Each ELECT single-serving sachet contains 1000 mg of sodium. View the result as a guideline, not an exact or medical recommendation.

The calculation is based on your measured sweat volume and a selected sodium profile (low/average/high salt content), which is a simplification of the actual sodium concentration in your sweat. The replacement range of 70–100% is a more cautious recovery recommendation, but the number of sachets is always based on the entire measured sodium loss — not just the replacement amount — so that the need is not underestimated. Each ELECT single-serving sachet contains 1000 mg of sodium. You can find your sweat loss in, for example, Garmin Connect or your Coros profile, or estimate it by weighing yourself before and after training.
