Energy Gel Calculator — How Many Gels for Your Ride
Calculate how many energy gels to carry for your ride duration and intensity.
How We Calculate This
Gel Requirement Calculation
- Carb target: 30 g/hr (easy) to 80 g/hr (race pace)
- Fuelling window = Ride duration - Time before first gel
- Total carbs needed = Carbs/hr x Fuelling hours
- Carbs from gels = Total needed - Carbs from other sources
- Gels needed = Carbs from gels / Carbs per gel
