Recreational 5k runners who prefer fizz
Plain sparkling water offers the carbonation you prefer when choosing a drink around a run. It does not take the place of carbohydrate in food or a fuelling drink.
Who is this choice for?
Runners planning harder or repeated sessions
Keep fluid and fuel as separate decisions. The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles; sparkling water alone does not provide a carbohydrate-fuelling plan.
Shoppers comparing flavoured drinks
If flavour matters, check the ingredients and nutrition panel rather than treating every sparkling drink as plain water. Products labelled as flavoured sparkling water can include sweeteners or acidity regulators.
What should you check?
Decide whether you want plain water or a flavoured drink, then check the pack format for where you plan to use it. Consider carbohydrate fuelling separately from the water you choose.
| Priority | What to check | Your needs |
|---|---|---|
| Plain or flavoured | Read the ingredients for flavourings, sweeteners and acidity regulators. Check the nutrition panel as well as any front-of-pack wording. | I want fizz without added flavourings, or I prefer a flavoured drink and know what is in it. |
| Carbohydrate fuel | Check the carbohydrate entry on the nutrition panel. The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles; do not use the word “water” as a guide to a drink’s fuel content. | Will this drink provide fluid only, or am I also looking for carbohydrate for a demanding training session? |
| Pack format | Compare the volume of each container and the number in the pack. Decide whether you want to carry one container or keep a larger bottle for before or after the run. | A single container I can carry matters more to me than the total size of the multipack. |
| Fluid needs | Consider the session, weather and how much you sweat rather than treating a bottle size as a drinking target. The NHS advises extra fluids after sweating from physical activity. | My choice needs to work for the conditions of this run, not a fixed amount printed on a bottle. |
Common buying mistakes
-
Expecting plain sparkling water to fuel the run
Plain sparkling water can be a fluid choice, but it is not a carbohydrate source. The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles.
If your training calls for carbohydrate, plan food or a separate carbohydrate-containing drink rather than relying on plain water.
-
Assuming flavoured sparkling water is just water with bubbles
Flavoured products can contain other ingredients. Volvic’s Touch of Strawberry Sparkling lists an acidity regulator and sweeteners, unlike Highland Spring’s description of its plain sparkling range.
Check the ingredients and nutrition panel of the particular drink you are buying, especially if you want plain water.
-
Using the bottle size as a race-day drinking rule
A 500ml container is a pack format, not a personal fluid requirement. The NHS advises extra fluids after sweating from physical activity.
Think about the conditions and your activity when deciding what to bring. Seek personalised advice if a medical condition affects your fluid or salt intake.
-
Reading mineral figures as a 5k performance ranking
A published mineral composition describes a water product; it does not by itself show that one plain sparkling water improves 5k performance over another.
Compare the ingredients, taste and container format for the way you intend to use the water.
Brand and retailer references
These ranges illustrate label and format differences; a brand’s presence here does not mean every product in its range has the same ingredients.
Highland Spring
Its plain sparkling spring-water range includes individual-bottle and larger-bottle formats.
- Highland Spring describes the plain range as water with nothing added but bubbles.
- That description does not make the water a carbohydrate fuel for running.
Buxton
Buxton offers sparkling natural mineral water, including individual-bottle formats.
- Buxton publishes mineral information for its sparkling water.
- A mineral listing is not evidence of a 5k fuelling advantage.
Volvic
Volvic offers flavoured sparkling spring-water drinks alongside its water range.
- The Touch of Strawberry Sparkling ingredients list identifies carbonated spring water, an acidity regulator and sweeteners.
- Check the particular flavour’s label rather than treating a flavoured drink as plain sparkling water.
Tesco
Tesco’s sparkling-water range includes own-label plain sparkling natural mineral water and flavoured products.
- Its grocery listings provide a way to compare container and multipack formats.
- Check the individual product label to distinguish plain water from a flavoured drink.
Sainsbury's
Sainsbury's has own-label flavoured sparkling-water drinks.
- Its Lemon & Lime product is labelled as a no-added-sugar flavoured spring-water drink with sweetener.
- “No added sugar” does not mean the ingredients are the same as plain sparkling water.

San Pellegrino Sparkling Natural Mineral Water 6 × 0.5L
Consider this plain sparkling mineral water if you want individual 0.5L bottles around a run. Choose carbohydrate separately if your training calls for fuel; the bottle size is not a drinking target.
No image available
Highland Spring Sparkling Spring Water 8 × 500ml
The eight individual 500ml bottles suit a preference for plain sparkling spring water in smaller containers. Highland Spring describes its plain sparkling range as having nothing added but bubbles; it is not carbohydrate fuel.
No image available
Buxton Sparkling Natural Mineral Water 8 × 500ml
Another plain sparkling-water option in eight individual 500ml bottles. Buxton’s published mineral information describes the water, but should not be treated as a running-performance claim or a reason to use it for carbohydrate fuelling.
No image available
Cano Water Sparkling Resealable 12 × 500ml
Consider this plain sparkling spring water if a resealable 500ml container suits how you carry a drink. The pack contains twelve cans rather than bottles; it is a water choice, not carbohydrate fuel.
No image available
San Pellegrino Sparkling Natural Mineral Water 6 × 1L
The six 1L bottles are an option if you prefer a larger container for before or after a run. A 1L bottle may be less convenient to carry during a run than a 500ml one; neither size sets how much you need to drink.
Questions about sparkling water and 5k runs
Can plain sparkling water fuel a 5k run?
No: plain sparkling water is a fluid choice, not a carbohydrate fuel. The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles. If your training calls for carbohydrate, consider food or a separate drink that supplies it.
Can I choose sparkling water for a drink around exercise?
Yes, if you prefer it and it suits you. The NHS advises extra fluids after sweating from physical activity; choose an amount that takes account of your activity and conditions rather than following the size of a particular bottle.
How can I tell plain water from a flavoured sparkling drink?
Read the ingredients and nutrition panel. Highland Spring describes its plain sparkling range as having nothing added but bubbles, while Volvic’s Touch of Strawberry Sparkling lists an acidity regulator and sweeteners. “No added sugar” does not mean a flavoured drink has the same ingredients as plain water.
Does a natural mineral water label show that it is better for running?
No. For natural mineral water produced and labelled in England, Department for Environment, Food & Rural Affairs guidance requires its composition to remain stable when tested. That product-category requirement does not establish a 5k performance advantage.
Should one bottle be my exact 5k drinking plan?
No. Container volume describes the product, not your individual fluid requirement. The NHS advises extra fluids after sweating from physical activity, so consider the run and its conditions when deciding what to bring.
