Choose regular cola only as a practised carbohydrate top-up, not as a complete marathon fuel or hydration plan. ASDA Groceries lists 35g carbohydrate in a 330ml Coca-Cola Original Taste can, while Joybuy lists 34g in a 330ml Pepsi Regular can; World Athletics advises 30–60g carbohydrate per hour for endurance exercise lasting 1–2.5 hours, but an individual plan must account for other fuel and fluids. Zero-sugar cola supplies no carbohydrate in the cited Coca-Cola Zero Sugar and Pepsi Max examples, so it cannot serve the same fuel purpose.
If carbohydrate intake during a long session is part of your plan, compare each can with your other fuel. World Athletics advises 30–60g carbohydrate per hour for endurance exercise lasting 1–2.5 hours and up to 90g per hour beyond 2.5 hours; those figures do not prescribe how much cola to drink.
The distinction matters when carbohydrate is the reason for carrying a can. ASDA Groceries lists 35g per 330ml Coca-Cola Original Taste can and 0g per Coca-Cola Zero Sugar can; Joybuy lists 34g for Pepsi Regular and 0g for Pepsi Max in the same can size.
A cola can should not stand in for a fluid and electrolyte plan. World Athletics describes fluid needs as highly variable, so consider the conditions, access to drinks and your practised intake separately from the carbohydrate in a can.
Consider it: When a carbonated drink you have already tried in training fits a planned carbohydrate top-up.
Trade-off: You still need to plan fluids separately and account for the drink alongside other fuel.
Consider it: When you want a cola drink but are not relying on it for carbohydrate.
Trade-off: The cited zero-sugar cans cannot contribute to a carbohydrate-fuel plan.
Consider it: When a long session calls for a deliberate approach to both carbohydrate and fluids rather than a cola can alone.
Trade-off: Products, quantities and carrying arrangements still need trying during training; World Athletics notes that fluid needs vary.
Start with carbohydrate per can and session duration, then check fluids, ingredients and whether the pack size is practical.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Read carbohydrate per can and account for other fuel. World Athletics advises 30–60g per hour for 1–2.5-hour endurance exercise and up to 90g per hour beyond 2.5 hours; neither range specifies a number of cola cans. | I want to know what one can contributes to my planned intake. ASDA Groceries lists 35g per 330ml Coca-Cola Original Taste can, Joybuy lists 34g for Pepsi Regular, and Tesco Groceries lists 14.8g available carbohydrate for Tesco Classic Cola. |
| Fluids and electrolytes | Plan fluid access and intake for the conditions rather than using carbohydrate content as a hydration measure. Check the current salt label; World Athletics describes fluid needs as highly variable. | For a long or hot run, I need a fluid plan that does not depend on cola alone. ASDA Groceries lists 0g salt in a 330ml Coca-Cola Original Taste can. |
| Sugar and ingredients | Check carbohydrate, sugars, caffeine-containing ingredients and sweeteners on the exact pack. ASDA Groceries lists 0g carbohydrate and sugars for Coca-Cola Zero Sugar; Joybuy lists the same figures for Pepsi Max. | If I am choosing cola for carbohydrate, a zero-sugar can will not do that job. If I want a cola drink without carbohydrate, I would still check its ingredients and try the exact drink before using it during a run. |
| Pack and serving size | Confirm the number of cans, volume per can and nutrition per can, not just per 100ml. Consider where a larger case will be stored and how a serving would fit into training. | I want a quantity I can use and store, with can-level figures that make my planned intake straightforward to work out. |
ASDA Groceries lists 0g carbohydrate per 330ml Coca-Cola Zero Sugar can, and Joybuy lists 0g for Pepsi Max. Neither supplies the carbohydrate described in World Athletics endurance guidance.
Read carbohydrate per can. If carbohydrate is the purpose, include a source you have tried in training within your overall intake plan.
World Athletics says fluid needs vary, while ASDA Groceries lists 0g salt per 330ml Coca-Cola Original Taste can. A carbohydrate figure does not tell you whether a drink addresses your fluid or electrolyte needs.
Plan fluids separately and consider the conditions and expected sweat loss when trying your approach on long training runs.
Tesco Groceries lists 14.8g available carbohydrate in a 330ml Tesco Classic Cola can, compared with 35g carbohydrate for the same size of Coca-Cola Original Taste at ASDA Groceries. The cited Tesco case contains eight cans, while the cited Coca-Cola case contains 24.
Compare can size, carbohydrate per can and pack count before deciding what quantity fits your plan.
A larger case also takes more storage space.
The cited regular and zero-sugar colas are carbonated and contain caffeine or caffeine-containing flavourings. How a particular serving fits into a training plan is individual.
Try the exact drink, serving size and timing during comparable training before deciding whether to carry it for an event.
The cited Coca-Cola multipacks include Original Taste and Zero Sugar in 24 x 330ml cans. ASDA Groceries lists 35g carbohydrate per Original Taste can and 0g per Zero Sugar can.
Joybuy lists Pepsi Regular and Pepsi Max in 24 x 330ml cases, with 34g and 0g carbohydrate per can respectively.
Tesco Groceries lists Classic Cola in an 8 x 330ml multipack, with 14.8g available carbohydrate per can.
These regular-sugar Coca-Cola and Pepsi cases are options for comparing can-level carbohydrate as part of a practised long-run plan. They are not complete fuel or hydration plans, and the larger Coca-Cola bundle needs more storage space.

For a practised carbohydrate top-up, the listed 35g per 330ml can can be counted alongside other fuel. This 24-can case contains carbonated cola with caffeine; check the current label and plan fluids separately.

For a planned carbohydrate top-up, Joybuy lists 34g per 330ml can in this 24-can case. The drink is carbonated and contains caffeine-containing flavourings; check the current salt label and plan fluids separately.

Each listed 330ml can provides 35g carbohydrate for a practised fuel plan. This bundle contains 96 cans, so check that the quantity and storage space suit you; the cola is carbonated and contains caffeine, and fluids need separate planning.
No single can establishes a complete fuel plan, though regular cola can contribute carbohydrate if you have tried it during training. ASDA Groceries lists 35g per 330ml Coca-Cola Original Taste can and Joybuy lists 34g per Pepsi Regular can; World Athletics advises 30–60g carbohydrate per hour for 1–2.5-hour endurance exercise and up to 90g per hour beyond 2.5 hours. Account for other fuel and plan fluids separately.
Choose regular cola only if its carbohydrate fits a plan you have tried in training; choose zero-sugar cola when you are not relying on the drink for carbohydrate. ASDA Groceries lists 0g carbohydrate per 330ml Coca-Cola Zero Sugar can, and Joybuy lists 0g for Pepsi Max. Neither choice replaces a fluid plan.
Do not assume it does. ASDA Groceries lists 0g salt per 330ml Coca-Cola Original Taste can, while the Australian Institute of Sport describes electrolyte products as designed to replace fluid and electrolytes, particularly sodium and potassium. World Athletics notes that fluid needs vary, so consider those needs separately from cola’s carbohydrate content.
Check the pack count, can volume, carbohydrate and sugars per can, plus the ingredients if caffeine or sweeteners matter to your choice. Compare the current physical pack with the serving you intend to use, and try the exact drink during training before relying on it during an event.
