Fueling Sources are the basis for every Fueling Plan. Your Fueling Sources are grouped by Type. Click + beside any Type heading to add Sources of that Type.

- The app contains a list of commonly used sources — Liquids, Drink Mixes, Electrolytes, Gels, Bars, and Chews — along with their nutritional content per serving (carbohydrates, fluid, and sodium)
- Use the Type dropdown to switch between lists of Liquids, Drink Mixes, and so on
- Use the Sort dropdown to sort by Name, Carbs, Fluid, or Sodium
Universal Sources (built into the system) are available to all users. Custom Sources — marked with a colored dot — allow Athlete and Coach Edition users to add Sources not included in the universal list.
Selecting Active Sources #
Your Fueling Sources list shows every Source you’ve added, grouped by Type. Use the Active checkboxes to indicate which Sources will be used when creating a Fueling Plan.

- Tick the checkbox in the B column to make a Source Active for the bike, in the R column for the run
- A Source can be Active for one sport, both, or neither
- Only Active Sources are used when adding or regenerating a Fueling Plan
Click the at the end of a row to remove a Source from the list entirely. (The Source will be removed from the list but not the library.)
Note: Drink Mixes and Electrolytes include only the mix, tab, etc. A Drink Mix must be assigned to a Liquid when you build the Fueling Plan, so you’ll want an Active Liquid, such as a water bottle. If there isn’t one, you can add it during Step 2 of creating the Plan.
Prioritizing Active Sources #
Give Active Sources a priority to control the order they’re listed in your Fueling Plan and used by the Auto-Fill feature.
- Type a number in the Priority column, separately for Bike and Run
- 1 is highest; the rest renumber themselves as you go
- Priority is optional — leave it blank and the Source is used after any prioritized ones
