Fueling Sources, Targets, and Plans work together to define your nutrition strategy for training and racing. Once your Sources have been chosen, Targets define the hourly nutrition goals, and the Plan brings it all together — optimizing serving quantities for each Active Source to best achieve the Fueling Targets.
Fueling Targets define the hourly nutrition goals during exercise:
- Sodium (mg/24oz) — sodium concentration goal per 24 oz of fluid consumed
- Carbs (g/hr) — carbohydrate intake goal per hour of exercise
- Fluid (oz/hr) — fluid intake goal per hour of exercise

The Fueling Tool offers default Carb, Fluid, and Sodium Targets to meet a range of individual fueling needs. Athlete and Coach Edition users can add individual Fueling Targets for greater specificity. Review the Fueling Guidelines to learn more about Fueling Targets for different exercise sports, durations, and environments.
