Choose regular cola only when you want a measured carbohydrate contribution during a longer or harder ride, with water and an electrolyte plan handled separately. Choose zero-sugar cola for the flavour rather than ride fuel, or a caffeine-free version if you want to avoid caffeine. Check the exact can: the sugar content of regular colas differs substantially.
On a longer or harder ride, a regular cola can make a measurable contribution to a carbohydrate plan. British Cycling discusses carbohydrate alongside fluids and electrolytes, so cola should not be the whole drinks plan.
For an easy ride, after a ride or when carbohydrate is coming from elsewhere, a zero-sugar cola offers the flavour without a meaningful carbohydrate contribution from the drink.
A labelled caffeine-free cola is the relevant choice if you want to avoid adding caffeine from a can, particularly when you also use coffee or caffeinated ride products. A zero-sugar label alone does not mean caffeine-free.
Start with carbohydrate per can, then check caffeine and whether a fizzy drink suits how you plan to use it. Keep water and electrolytes in the ride plan separately.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate per can | Compare carbohydrate and sugars for the exact can size and recipe. Joybuy lists 35g sugars per 330ml Coca-Cola Original Taste can; Pepsi UK lists 15g per 330ml Pepsi Classic can, and Tesco Groceries lists 14.5g per 330ml Tesco Classic Cola can. Check the pack rather than applying another product’s figure. | For a longer or harder ride, I want to know what one can contributes to my planned carbohydrate intake. |
| Zero-sugar choice | Read both the sugars and carbohydrate lines. Pepsi UK lists 0g of each per 330ml Pepsi Max can; its caffeine-free Max has 0g sugars and 0.2g carbohydrate per 330ml. | If my ride fuel comes from food or another product, I may want cola flavour without treating the drink as a carbohydrate source. |
| Caffeine | Check whether the exact variant contains caffeine and account for other sources. Coca-Cola GB states that a 330ml Coke can contains 34mg; Pepsi Max contains caffeine, while Pepsi Max Caffeine-Free is labelled caffeine-free. | I want to avoid adding caffeine on a later ride, or keep track of it alongside coffee and caffeinated gels. |
| Fizz and carrying | Try the chosen carbonated drink during training before relying on it at an event. Consider whether a 330ml can is practical to carry, open and finish on your route. | I would rather establish how a fizzy can fits my ride before buying a multipack for an event. |
| Regular use | Distinguish deliberate ride fuelling from repeatedly drinking sugary cola for hydration. The NHS gives a general adult limit of 30g free sugars a day; UK government oral-health guidance also identifies sugar-containing drinks as relevant to dental caries. | Outside a planned fuelling use, I want water to cover my ordinary hydration needs. |
A 330ml Coca-Cola Original Taste can is listed by Joybuy at 35g sugars, while Pepsi UK lists 15g for Pepsi Classic and Tesco Groceries lists 14.5g for Tesco Classic Cola. The same can size does not mean the same carbohydrate contribution.
Read carbohydrate and sugars per can on the exact pack before counting it towards a ride plan.
Pepsi UK lists Pepsi Max at 0g carbohydrate and 0g sugars per 330ml can; a zero-sugar cola does not provide a meaningful carbohydrate contribution.
If you need carbohydrate during the ride, plan it from food or another drink rather than relying on zero-sugar cola.
A 330ml Coca-Cola Original Taste can lists 35g sugars. The NHS advises a general adult limit of 30g free sugars a day, while UK government oral-health guidance links sugar-containing drinks with dental caries.
Keep any use of regular cola tied to a deliberate fuelling plan, and use water for ordinary hydration.
Caffeine from cola adds to other sources. A 1992 study published in the International Journal of Sport Nutrition found no significant overall difference in perceived stomach comfort or exercise performance with carbonation in eight male cyclists, but those trials cannot predict how an individual will respond.
Check the variant’s caffeine and ingredients information, and try the drink during training before using it at an event. Choose a labelled caffeine-free variant if avoiding caffeine matters to you.
Compare individual recipes rather than treating a brand name as a guide to carbohydrate or caffeine content.
Original Taste is a regular-cola option for a measured carbohydrate contribution; Zero Sugar serves a different, non-fuelling purpose.
The listed Pepsi recipes cover regular, zero-sugar caffeinated and zero-sugar caffeine-free choices.
Tesco Classic Cola is an own-label regular-cola reference for comparing carbohydrate per can.
These 24 x 330ml can packs include regular cola for a planned carbohydrate contribution and zero-sugar choices for cola flavour without ride fuel, including a caffeine-free variant.

For a planned carbohydrate contribution during a longer or harder ride. Joybuy lists 35g carbohydrate and sugars per 330ml can; Coca-Cola GB states that a 330ml Coke can contains 34mg caffeine. Keep water and electrolytes in a separate ride plan.
No image available
For cola flavour when you want to avoid caffeine, not for carbohydrate fuelling. Pepsi UK lists 0g sugars and 0.2g carbohydrate per 330ml can for this caffeine-free variant. Check the pack ingredients if sweeteners are relevant to your choice.

For cola flavour without carbohydrate from the drink when caffeine is acceptable. Pepsi UK lists 0g carbohydrate and 0g sugars per 330ml can; its ingredients include caffeine. Plan ride fuel separately if you need it.

A sugar-containing regular cola to consider for a planned ride contribution. Check carbohydrate and sugars per can on the exact pack before calculating that contribution; do not assume another Pepsi listing describes this pack’s recipe. It contains caffeine and does not replace separate water and electrolyte planning.
No: regular cola can contribute carbohydrate, but it does not cover the whole fluid and electrolyte plan. British Cycling treats carbohydrate, hydration and electrolytes as separate parts of prolonged-ride nutrition. Check the exact can’s carbohydrate content and plan water and electrolytes for your ride separately.
Not a meaningful amount of carbohydrate. Pepsi UK lists Pepsi Max at 0g carbohydrate and 0g sugars per 330ml can. It may suit someone who wants cola flavour while getting planned ride carbohydrate elsewhere.
Not necessarily, but a study cannot establish your individual tolerance. In a 1992 International Journal of Sport Nutrition study involving eight male cyclists, carbonation did not significantly change perceived stomach comfort overall during 120-minute trials. Try your chosen drink during training before relying on it at an event.
Count cola alongside other caffeine sources, including coffee and caffeinated ride products. Coca-Cola GB states that a 330ml Coke can contains 34mg caffeine. If you want to avoid caffeine, check that the exact multipack says caffeine-free; zero-sugar Pepsi Max and Pepsi Max Caffeine-Free are different variants.
Check can size, carbohydrate and sugars per can, caffeine status and the ingredients on the exact variant. Those details tell you whether the can contributes to your planned ride carbohydrate and whether it fits your caffeine preference; pack count alone cannot answer either question.
