For a short ride, a zero-sugar fizzy drink can be a choice for taste before or afterwards, with fluids for the ride planned separately; choose a labelled caffeine-free version if you want to avoid caffeine. For longer rides, plan carbohydrate and fluids rather than relying on a zero-sugar drink: British Cycling’s guidance for indoor rides over 90 minutes suggests 30–60 g of carbohydrate per hour. Regular cola contains sugar, but sugar content alone does not establish that it meets a ride’s fluid and electrolyte needs.
If the drink is for enjoyment rather than ride fuel, compare regular and zero-sugar varieties by their labels. A caffeine-free version gives you another choice if you do not want caffeine; plan fluids for the ride separately.
Carbohydrate and fluids matter more than whether a drink is fizzy. British Cycling’s guidance for indoor rides over 90 minutes suggests 30–60 g of carbohydrate per hour, so check how a drink fits alongside any food you plan to take.
Zero sugar does not mean caffeine-free. Look for an explicit caffeine-free label and consider caffeine from other drinks or cycling products you use.
Decide whether the drink is for taste or part of your ride plan, then compare the exact pack’s nutrition and ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Ride fuel | Check carbohydrate per 100 ml and per serving, then consider the amount you would drink alongside food. British Cycling suggests 30–60 g of carbohydrate per hour in its guidance for indoor rides over 90 minutes. | For a longer session, I need a carbohydrate plan, not just a drink chosen for its flavour or fizz. |
| Sugar choice | Compare sugars per 100 ml and per serving on the exact pack. Pepsi UK lists 0 g sugars per 100 ml for Pepsi Max; a zero-sugar choice is not a source of ride carbohydrate. | After an easy ride, I might want a fizzy drink without adding sugar from the drink, while keeping my ride fuel and fluids separate. |
| Caffeine | Look for an explicit caffeine-free designation rather than assuming that “zero sugar” means no caffeine. Include coffee, tea and cycling products when considering your intake. | I want to know whether my drink adds caffeine, especially if I use other caffeinated products. |
| Practical use | Check the pack’s ingredients and serving size. British Cycling advises using training rides to establish which foods and products work for you on the bike. | If I plan to drink it while riding, I want to find out in training whether it suits my routine. |
A zero-sugar fizzy drink is not a meaningful source of the carbohydrate needed in a longer-ride fuel plan.
Plan food or a carbohydrate-containing drink for the session. British Cycling’s guidance for indoor rides over 90 minutes suggests 30–60 g of carbohydrate per hour.
Sugar content alone does not tell you whether a cola provides the fluid and electrolyte combination you intend to use on a ride.
Compare its carbohydrate content and ingredients with your full ride plan rather than treating “contains sugar” as a complete fuelling strategy.
A zero-sugar cola may still contain caffeine, which also appears in some coffees, teas and cycling products.
Choose a drink explicitly labelled caffeine-free when that matters to you, and consider your other caffeine sources.
Sugar, sweeteners and caffeine statements can differ between drinks in the same brand range.
Check the current pack for the specific flavour and size you are buying, including its ingredients and nutrition per 100 ml.
These ranges illustrate different label choices; a brand name alone does not establish whether a particular drink suits a ride plan.
Coca-Cola Great Britain lists Coca-Cola Zero Sugar and a separately named Caffeine Free version.
Pepsi UK lists Pepsi Max with 0 g sugars per 100 ml and a distinct Pepsi Max No Caffeine product.
Sprite is a lemon-and-lime alternative to cola for riders choosing a fizzy drink for taste.
Coca-Cola Great Britain lists Fanta among its drink brands.
Coca-Cola Great Britain lists a Dr Pepper Zero variant for shoppers comparing regular and zero-sugar drinks.
Tesco lists both a Diet Cola with caffeine and a separate Caffeine Free Diet Cola.
These options include fizzy drinks for choosing by taste, sugar or caffeine, alongside sports drinks to consider when planning carbohydrate and fluids for a ride.

This 325ml carbonated drink is an option to examine if you want a fizzy sports drink rather than a zero-sugar soft drink. Check its current pack for carbohydrate and electrolyte amounts, and for caffeine if that affects your choice; work out how it fits your full ride plan.

A 24-pack of 330ml cans for a zero-sugar fizzy-drink choice when ride fuel is not the purpose. Check the current pack for its caffeine statement, sweeteners and phenylalanine information if those affect your choice; plan carbohydrate separately for a longer ride.

This 24-pack of 330ml cans is a cola option when a caffeine-free variant matters more than ride fuel. Check the current pack’s sugar, sweetener and phenylalanine statements; arrange fluids and carbohydrate separately for longer cycling sessions.

This four-pack of 500ml sports drinks is an option to assess for a longer-ride carbohydrate and fluid plan, rather than assuming it is a fizzy soft drink. Check the current pack’s carbohydrate, electrolyte, caffeine and ingredient information, and try your chosen plan in training.
Not as the carbohydrate source in a longer-ride plan: a zero-sugar drink supplies little or no sugar. British Cycling’s guidance for indoor rides over 90 minutes suggests 30–60 g of carbohydrate per hour. Plan food or a carbohydrate-containing drink alongside your fluids, and try the plan in training.
Sugar in cola does not, by itself, establish that the drink is isotonic or supplies the electrolytes you want for cycling. British Cycling describes isotonic drinks as having a concentration of around 5–8%; check the exact drink’s carbohydrate and ingredients against your ride plan rather than judging it by sweetness.
Choose a drink explicitly labelled caffeine-free, rather than relying on a zero-sugar name. Coca-Cola Great Britain lists Coca-Cola Zero Sugar Caffeine Free, Pepsi UK lists Pepsi Max No Caffeine, and Tesco lists Caffeine Free Diet Cola. Check the current pack of the variant you buy.
Yes. Compare the exact pack’s sugars per 100 ml and per serving, ingredient list and caffeine statement. Flavours and variants need not share a formulation, and Tesco advises shoppers to read the pack because product information can change.
