For a typical 5k, choose food or a suitable carbohydrate drink if you need fuel, and water to replace fluid lost through sweating, in line with UK Sports Institute and NHS guidance. Choose a fizzy-drink multipack for an occasional post-run drink rather than assuming its sugar makes it suitable running fuel.
If you are choosing between breakfast, a snack and a canned drink, start with what you can comfortably eat or drink before running. UK Sports Institute guidance includes a carbohydrate drink as an option when you have missed breakfast; it does not make a fizzy-drink multipack the default choice.
If the can is for flavour rather than fuel, compare its sugar information with what you want from the drink. After sweating, the NHS identifies water as the best way to replace lost fluid.
Check the exact can’s ingredients when caffeine, sweeteners or a phenylalanine statement affects your choice. Similar-looking multipacks need not have the same formulation.
Decide whether you need fluid, carbohydrate or simply a drink you enjoy after the run. Then compare cans by their serving labels, not just the multipack size.
| Priority | What to check | Your needs |
|---|---|---|
| Replacing fluid | Consider what you will drink after sweating. The NHS identifies water as the best way to replace lost fluid; a preferred fizzy flavour is a separate consideration. | I want a straightforward drink after my run and can choose a fizzy can separately for its flavour. |
| Carbohydrate before running | Check whether you have time for food and whether you tolerate it before a run. UK Sports Institute guidance also allows for a carbohydrate drink if breakfast has been missed. | If I cannot eat beforehand, I need a carbohydrate option I can trial before the event, rather than relying on a canned soft drink by default. |
| Sugar per can | Compare the same serving size. Tesco lists 35 g sugars per 330 ml for Coca-Cola Original Taste and 0 g for its listed Sprite No Sugar; its Fanta Orange Zero listing gives 2.0 g despite the no-added-sugar wording. | For a taste-led drink, I want to know what one can contains. I will not assume that “no added sugar” means zero sugars. |
| Caffeine and ingredients | Read the current ingredients for caffeine, sweeteners and any phenylalanine statement. The researched Coca-Cola Original Taste and Pepsi Classic listings include caffeine; Tesco labels its listed Sprite No Sugar product caffeine-free. | Caffeine matters to me, so I need to check the particular multipack and account for other drinks I have. |
Tesco lists 35 g sugars in a 330 ml Coca-Cola Original Taste can, but that figure alone does not establish whether the drink suits your run, its timing or your tolerance.
Decide whether you need carbohydrate before choosing a drink. If you do, trial a suitable food or drink before the event rather than making cola your default.
Tesco lists 0 g carbohydrate per 330 ml for its Sprite No Sugar product. Its Fanta Orange Zero listing gives 2.0 g per 330 ml. Neither label makes those products a substitute for planning food when you need it.
Choose a no-sugar drink for flavour if that suits you, and consider your pre-run food separately.
The researched Coca-Cola Original Taste and Pepsi Classic listings include caffeine, while some of the listed drinks contain sweeteners or carry a phenylalanine statement.
Read the ingredients on the exact can, particularly if you limit caffeine or need to check sweeteners or phenylalanine.
Ingredients and nutrition information can change, so an earlier listing may not describe the can you receive.
Check the pack in hand when sugar, caffeine or specific ingredients affect your choice.
These label examples describe particular UK product listings, not every drink or pack sold under each brand.
Original Taste is a regular cola option for a flavour-led purchase.
Pepsi Classic is another regular cola to compare by its per-can label.
The researched Sprite No Sugar listing is a lemon-and-lime option for a taste-led drink without listed sugar.
Fanta Orange Zero offers an orange-flavoured alternative to the researched colas.
The researched Dr Pepper 8-pack is a flavoured fizzy-drink choice rather than a running-specific drink.
These canned multipacks are options for an occasional fizzy drink around a 5k. Choose pre-run fuel and fluid replacement on their own terms rather than treating the cans as a running plan.

A multipack to consider if you want a fizzy can after running. Check the current label for sugar, caffeine, sweeteners and any phenylalanine statement where these affect your choice.
No image available
Another 24-can option for a taste-led drink after a run. Read the can label if sugar, caffeine, sweeteners or phenylalanine information matters to you; plan any needed carbohydrate separately.
No image available
The No Sugar variant is a smaller multipack for an occasional fizzy drink, not a substitute for planning pre-run food. If you avoid caffeine or need to check sweeteners, read the label on this exact pack.
No image available
A cola multipack for someone choosing flavour after a run rather than a drink-based fuelling plan. Check sugar and caffeine information per can, along with sweeteners, on the current label.
No image available
The Zero Sugar variant is an option if you want cola flavour without choosing regular sugary cola. It is not a pre-run food choice; check caffeine, sweeteners and any phenylalanine statement on the current can if relevant.
No: do not choose one on the assumption that its sugar makes it suitable running fuel. UK Sports Institute guidance gives carbohydrate-containing food before a run as an option, or a carbohydrate drink if breakfast has been missed; trial timing and tolerance before an event.
Do not rely on it for carbohydrate. Tesco lists 0 g carbohydrate per 330 ml for its researched Sprite No Sugar product and 2.0 g per 330 ml for its Fanta Orange Zero product. If you need pre-run food, plan that separately.
You can choose cola for its flavour, but the NHS identifies water as the best way to replace fluid lost through sweating. Keep that rehydration need separate from whether you fancy a fizzy drink.
Compare the can size and sugars per can, then read the ingredients for caffeine, sweeteners and any phenylalanine statement. Check the pack you receive, because ingredients and nutrition information can change.
Count caffeine from all sources, including cola: the NHS advises no more than 200 mg a day during pregnancy. Check the caffeine information for the particular drink before choosing it; a product name or pack colour is not enough to establish its caffeine content.
