The target is separated from estimated energy, so products close a chosen carbohydrate plan without implying all calories must be replaced.
How to use this calculator
- 1Choose power-based or manual energy.
- 2Enter your own hourly or weight-based carbohydrate target.
- 3Add product servings and review whole gels and timing.
Formula
kcal = kJ ÷ efficiency ÷ 4.184
Rate × hours sets the carbohydrate target; products close the remaining grams.
Calculation steps
- Estimate energy.
- Calculate selected carbohydrate target.
- Count products and round gels upward.
Worked example
A 3-hour ride at 60 g/h targets 180 g; products supplying 160 g leave one 25 g gel.
Assumptions
- The rate is user selected.
- Efficiency varies.
- Product labels are accurate.
- Hydration and daily nutrition are excluded.

Frequently asked questions
Does calorie burn equal carb target?
No; they are different planning quantities.
Why round gels up?
Products are whole items; surplus is reported.
Is more than 90 g/h always better?
No; tolerance and context matter.
Does the schedule assign products?
No; it evenly spaces target grams.
