LYTEWORK SYSTEM
Hydration Calculators
Hydration is a performance variable you can control. Sodium loss, sweat rate, temperature, and duration all influence how much electrolyte support you need. The tools within the Lytework Hydration Intelligence System translate sweat rate, sodium loss, and environmental conditions into clear hydration protocols.
THE LYTEWORK SYSTEM
Explore the Hydration Intelligence System
Use the tools within the Lytework Hydration Intelligence System to estimate sweat loss, sodium intake, hydration strategy and race fueling before race day.
Hydration Intelligence System
Build a personalised hydration and fuelling strategy using your physiology, environment, and session details.
Sweat Rate Calculator
Estimate sweat loss during training and racing to guide your plan.
Lytework Sodium Protocol Calculator
Estimate how much sodium you lose through sweat and determine your optimal mg/hour sodium target.
Race Fueling Calculator
Build a carbohydrate, fluid and sodium strategy for endurance races.
Ironman Hydration Calculator
Estimate sodium loss, capsule needs, and a complete race-day hydration strategy for Ironman and 70.3 events.
Race Nutrition Diagnostic
Diagnose what went wrong in your last race or session. Identify the likely root cause of cramping, bonking, or GI distress — and learn what to refine next time.
How to use the system
Turn hydration into a repeatable system
The Lytework tools work together to help endurance athletes estimate sweat loss, refine sodium intake and build practical hydration strategies for training and racing.
