How to use the PurePower Fuel Calculator

The PurePower Fuel Calculator is designed to help endurance athletes – whether you run or cycle – plan their nutrition and hydration for training sessions and races. By entering a few key parameters, you get a personalised recommendation of PurePower products tailored to your specific effort.

Running

For running, the calculator recommends primarily Energy Gel Caffeine and Energy Chew Bars, as these are easy to carry and consume on the move. On longer efforts such as a half marathon or marathon, an Energy Snack bar is recommended 1–2 hours before the start to build a solid carbohydrate base. The calculator takes into account your pace, distance or duration, body weight, temperature, and experience level to estimate your carbohydrate and fluid needs per hour.

Cycling

For cycling, Carbo Race Electrolyte is the primary energy source – mixed into your water bottle at a rate of one sachet per 500 ml. Gels and Chew Bars are recommended as supplements to cover any remaining carbohydrate needs. On longer rides, an Energy Snack bar provides solid food variety and sustained energy. You can optionally enter your average watt output and total elevation gain to get a more precise recommendation.

Experience levels

The calculator offers three experience levels that adjust the recommended carbohydrate intake per hour. Beginner athletes typically benefit from 40–50 g of carbohydrates per hour, while intermediate athletes can absorb 50–60 g/h, and advanced athletes with trained gut absorption may use up to 70–90 g/h. These ranges are based on current sports nutrition research guidelines.

Temperature and hydration

Fluid needs increase significantly in warm conditions. The calculator automatically adjusts the hydration recommendation when temperatures exceed 20°C. Hydro Tabs Electrolyte are recommended to replace electrolytes lost through sweat – one tube of 20 tabs is sufficient for most training sessions and races.

Important note

All recommendations are guidelines based on general sports nutrition principles for endurance sport. Individual needs vary depending on fitness level, metabolism, and personal tolerance. Always test your nutrition strategy in training before race day – never try new products for the first time in a competition. Consult a sports nutritionist if you have specific dietary requirements or health concerns.
