Estimates nutritional needs (calories, fluids, electrolytes) during triathlon training or racing.
Start with your values, or try a preset.
Enter Body Weight, Activity Duration, Intensity Level, Ambient Temperature, and Estimated Sweat Rate in the units shown.
Read Sodium Intake per Hour (approximate), Fluid Intake per Hour (approximate), Calories per Hour (approximate), Total Sodium Intake (approximate), Total Fluid Intake (approximate), and Total Calories Needed (approximate) in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
See the inputs and their calculated results.
