Choose plain sparkling water if you want a fizzy drink for hydration around a 5k, not carbohydrate fuel. The NHS advises replacing fluid lost through physical activity, while the Australian Institute of Sport describes sports drinks as supplying carbohydrate and fluid together; consider that different type of drink when your exercise plan calls for it, rather than simply because the run is 5 km. If cans matter to you, check the container type as well as the pack count before buying.
The useful distinction is whether you want a drink for fluid intake, a particular pack format or a product that also supplies carbohydrate.
A sparkling-water multi-pack may suit your preference for a fizzy drink before or after a run. If you are shopping for run fuel, check that separately: the Australian Institute of Sport describes carbohydrate-containing sports drinks as serving a different purpose from plain water.
If avoiding sugar is part of your choice, read the ingredients and nutrition panel for the exact product. A flavoured sparkling drink should not automatically be treated as plain sparkling water; Marks & Spencer describes its lemon-and-lime sparkling water as lightly sweetened.
Check the container and individual volume, not just the words “sparkling water multi-pack”. The sparkling-water packs shown in Tesco and Sainsbury’s category listings include 500 ml bottles, which will not meet a can-format preference.
Decide what the drink needs to do first, then compare the label and the exact pack format. A 5k distance alone does not establish a need for a carbohydrate-electrolyte drink.
Choose it when: You want water for fluid intake and prefer carbonation.
Keep in mind: Plain sparkling water is not carbohydrate fuel; check the listing separately if you need cans rather than bottles.
Choose it when: You want water without carbonation around your run.
Keep in mind: Like plain sparkling water, it does not take the place of carbohydrate fuelling when your exercise plan calls for it.
Consider it when: Your activity and individual plan call for carbohydrate, fluid and electrolytes together, the role described by the Australian Institute of Sport.
Keep in mind: It is a different product from plain water, so check its label against what you intend to drink.
| Priority | What to check | Your needs |
|---|---|---|
| Hydration or fuel | Read the drink type and carbohydrate information on the label. The NHS discusses water for replacing lost fluids; the Australian Institute of Sport describes sports drinks as providing carbohydrate and fluid together. | I want a drink for fluid intake around a 5k, but I do not want to mistake plain sparkling water for carbohydrate fuel. |
| Container and portion | Confirm cans or bottles, units per pack and volume per unit. Tesco and Sainsbury’s list sparkling-water bottle packs in formats including 12 x 500 ml and 8 x 500 ml. | Will individual containers be convenient to carry, chill and store, or am I buying a pack for use at home? |
| Plain or flavoured | Check the product name, ingredients and nutrition panel. Marks & Spencer describes its Lemon and Lime Sparkling Water as lightly sweetened, so the flavour description alone does not settle what is in the drink. | I prefer plain sparkling water and want to know whether the particular flavoured drink I am considering is sweetened. |
Plain sparkling water supplies fluid but not the carbohydrate role that the Australian Institute of Sport describes for sports drinks. It leaves a separate fuelling decision unanswered.
Decide whether you want water for fluid intake or a drink that supplies carbohydrate, then read the nutrition label rather than judging by the packaging.
Tesco and Sainsbury’s sparkling-water listings include bottle multi-packs. A bottle pack may not suit the way you intended to carry or store individual drinks.
Check the container type, pack count and volume per unit on the exact product listing before ordering.
A flavour name does not tell you whether a drink is sweetened. Marks & Spencer describes one of its lemon-and-lime sparkling-water products as lightly sweetened.
If you want plain water, confirm the product name, ingredients and nutrition information for the specific variant.
A brand’s range can include different containers and pack sizes. Use these examples to narrow your search, then check the exact product listing rather than assuming every format is a can multi-pack.
S.Pellegrino lists a 33 cl can on its own product page, while Tesco and Sainsbury’s list a 6 x 500 ml sparkling-water bottle pack.
Perrier describes a slim-can format for its carbonated mineral water on its product page.
Highland Spring describes its sparkling water as having nothing added but bubbles; Tesco and Sainsbury’s list an 8 x 500 ml sparkling-water bottle pack.
Tesco lists its own-label British Natural Mineral Water Sparkling in a 12 x 500 ml format.
Sainsbury’s lists its own-label British Bottled Sparkling Spring Water in a 12 x 500 ml format.
M&S lists still, sparkling and flavoured waters, with availability dependent on the selected Foodhall.
These options are plain sparkling-water multi-packs for shoppers choosing a fizzy drink around a 5k. The listed packs contain bottles rather than cans, and plain sparkling water is not carbohydrate run fuel. Compare individual bottle sizes before choosing one for home storage or for taking out.

A plain sparkling-water option for fluid intake around a 5k, rather than carbohydrate fuel. This pack is described as six 500 ml bottles, not cans; check that the individual size suits how you plan to use it.

Choose this for plain sparkling water if eight individual 500 ml bottles suit your storage and carrying plans. It is a bottle pack, not a can pack, and serves a hydration rather than carbohydrate-fuelling purpose; check the product label if specific nutrition details matter to you.
No image available
This plain sparkling-water pack offers eight 500 ml bottles for fluid intake around a run. The listing identifies carbonated natural mineral water and states 0 g carbohydrate and sugars per 100 ml; it is not a can pack or a carbohydrate-fuelling drink.
No image available
Six 1 L bottles make this a larger-unit option for keeping sparkling water at home. Check whether that bottle size suits your storage and portions: these are not cans, and the water does not replace carbohydrate fuel.
No image available
This six-bottle pack provides 1 L units of sparkling natural mineral water for shoppers who prefer larger bottles at home. It does not meet a can-format preference; compare the bottle size with the portions you want, and treat the drink as hydration rather than carbohydrate fuel.
No: plain sparkling water is a drink for fluid intake, not a source of the carbohydrate supplied by carbohydrate-electrolyte sports drinks. The Australian Institute of Sport describes those sports drinks as providing carbohydrate and fluid together, so keep fuelling and hydration as separate decisions.
Consider a carbohydrate-electrolyte sports drink when your activity and individual exercise plan call for carbohydrate, fluid and electrolytes together. The Australian Institute of Sport describes that combined role; running 5 km by itself does not determine which drink you need.
No. Tesco and Sainsbury’s list sparkling-water multi-packs containing bottles, including 12 x 500 ml own-label formats. Check the container, number of units and volume on the exact listing if cans are important to your purchase.
Read the ingredients and nutrition panel for the exact variant rather than relying on its flavour name. Marks & Spencer describes its Lemon and Lime Sparkling Water as lightly sweetened, so a flavoured sparkling drink should not be assumed to be the same as plain sparkling water.
