Marathon Fueling Interval Calculator

Calculate optimal gel/sports drink intake intervals for a marathon based on target race pace, body weight, and sweat rate to prevent glycogen depletion and maintain optimal hydration

Each component has a specific meaning:

• Target race pace — The target race pace recorded for the scenario being assessed.
• Body weight — The body weight recorded for the scenario being assessed.
• Sweat rate — The sweat rate recorded for the scenario being assessed.

Note: Interpret the marathon fueling result against the thresholds and context described above.

Enter the target race pace, body weight, sweat rate for the scenario you are assessing. Calculate optimal gel/sports drink intake intervals for a marathon based on target race pace, body weight, and sweat rate to prevent glycogen depletion and maintain optimal hydration. Use the marathon fueling result to inform your calculation.
