Sports Drinks for Cycling: Compare Carbohydrates per Bottle, Not Just Scoops

Sports drinks for cycling are best compared by grams of carbohydrate in the bottle you will actually drink, then by how long it will last. Scoop size and bottle volume alone cannot tell you that. Include food in the same calculation, and keep your fluid plan separate.

For a concrete example, one 40 g serving of Frank Active Focus+Energy contains 36.4 g of carbohydrate. Finish it over an hour and that averages 36.4 g per hour; spread the same bottle across two hours and it averages 18.2 g per hour.

Sports drinks for cycling: when should you plan carbohydrate intake?

The Australian Institute of Sport (AIS) sports-drink guidance (accessed September 2026) gives 30–60 g of carbohydrate per hour as a general target for endurance exercise lasting 1–2.5 hours. It lists no carbohydrate requirement during brief exercise under 45 minutes. These are sport-nutrition guidelines, not a requirement to buy a sports drink for every bike trip.

For this guide, think of a sustained weekend ride rather than a short trip to the shops. A longer or harder session makes a planned bottle-and-food approach more relevant. Your intensity, goals and individual circumstances determine which plan is appropriate.

Why compare carbohydrate per bottle instead of scoops?

A scoop measures powder, not carbohydrate. Different powders can use different scoop sizes and include different proportions of other ingredients. Even a '40 g serving' does not necessarily contain 40 g of carbohydrate.

The Frank Active nutrition panel and directions give the two numbers separately: 40 g powder contains 36.4 g carbohydrate. The serving is two scoops mixed into 450–750 ml of water.

Both examples sit within the directed mixing range. The larger bottle is more dilute, but it still contains the same total carbohydrate. This table compares the contents of a bottle; it does not prescribe how much fluid you should drink.

How do you calculate carbohydrate per hour?

If you finish only half the bottle, count half its carbohydrate: 18.2 g. If you also eat a bar or gel, add the carbohydrate declared for the amount you consume. These are averages for checking a plan, not instructions to drink everything at once.

What could a two-hour bottle-and-food plan look like?

Here is an arithmetic example, not a personalised target. Suppose you have chosen to plan around 40 g per hour for a two-hour ride. That is 80 g across the ride. One full Frank Active serving contributes 36.4 g, leaving 43.6 g to account for through other food or drink.

• Total planned: 40 g/h × 2 hours = 80 g carbohydrate.
• From one Frank Active serving: 36.4 g.
• Remaining in this example: 80 − 36.4 = 43.6 g.

Use the actual labels on your chosen foods to fill that remaining amount; a generic 'one snack' is not a fixed quantity of carbohydrate. You do not need to eat exactly 43.6 g. The decimal shows the calculation, not a precision requirement.

Stay within the product directions: no more than two Frank Active servings per day. That is a daily limit, not an hourly allowance. Do not keep adding scoops or repeat servings indefinitely to match an endurance target. Check Frank Active's current usage directions.

Should you drink more just to reach a carbohydrate target?

Not automatically. The AIS guidance treats fluid and fuel needs as related but distinct: they can differ with the rider and conditions. It describes using food or other sports products alongside a drink when carbohydrate needs are higher than fluid needs.

This is why 'one bottle per hour' is not a universal rule. Work out the carbohydrate your bottle supplies, then consider the fluid you need and what you will carry. A refill stop might change your water supply without adding carbohydrate.

Try your proposed food-and-drink combination during training before relying on it for an important event. Keep a simple note of what you consumed and how the plan fitted the ride, rather than changing several products at once.

Where does Frank Active fit in a cycling kit?

Its practical appeal is a measured powder serving you can prepare before leaving home. For riders who want some of their carbohydrate in a bottle, the declared amount makes it easy to include in a wider food-and-drink plan. The prepared drink is clear and colourless despite its mango flavour.

If you are still choosing a drink category, our isotonic, electrolyte and energy drink comparison covers that decision. Here, the next step is simpler: compare the carbohydrate in your planned bottle, check how long it will last, and see whether Frank Active fits your ride routine.

Frequently asked questions

How many carbohydrates are in a Frank Active bottle?

A bottle made with one 40 g serving contains 36.4 g of carbohydrate. Use the directed 450–750 ml of water; the total carbohydrate stays the same across that dilution range.

Does one bottle provide enough carbohydrate for a two-hour ride?

One full Frank Active serving supplies 36.4 g in total, or an average of 18.2 g per hour over two hours. Whether to add food depends on your ride and fuelling plan.

Can I add extra scoops to reach an hourly carbohydrate target?

Do not increase the powder beyond the directions to chase a target. Frank Active directs 40 g in 450–750 ml of water and a maximum of two servings per day; other food or drink can provide additional carbohydrate where appropriate.

Should a mango-flavoured Frank Active drink look yellow?

No. The prepared drink is clear and colourless; mango describes its flavour, not its colour.

Follow the product directions, including the maximum of two servings per day. Seek individual advice from a sports dietitian if you need a tailored fuelling plan.
