Choose diluted cordial if you want a flavoured drink and can prepare it with water; choose ready-to-drink cans if unopened single servings matter more. They are different drink formats, and neither should be assumed to provide carbohydrate fuel for a 5K. The American College of Sports Medicine says most people exercising for less than 60–90 minutes in normal weather are unlikely to become dehydrated or depleted of electrolytes; check the drink’s nutrition and ingredients for the purpose you have in mind.
If you want something to drink around a short run, start with a drink you are comfortable consuming rather than assuming you need a sports drink. The NHS identifies water as the best way to replace fluids lost through physical activity.
A multipack may suit a preference for unopened, ready-to-drink servings. Check the product description: the Tesco and Sainsbury’s ranges list canned soft drinks separately from bottled cordials.
Check nutrition for the prepared drink if carbohydrate matters to your choice. Sainsbury’s lists 2.1g carbohydrate per prepared 250ml serving of its no-added-sugar lime cordial; that figure describes that product, not all cordials.
Decide whether you need a drink that is ready to open or a concentrate you can dilute, then compare nutrition on the basis you will actually drink it.
| Priority | What to check | Your needs |
|---|---|---|
| Drink purpose | Consider run duration and weather before choosing a drink for electrolyte replacement. Check carbohydrate per prepared serving or per can if you expect the drink to provide fuel. | For a short run in normal weather, I want a drink I can comfortably have, without assuming I need an electrolyte product. The American College of Sports Medicine says most people exercising for less than 60–90 minutes in normal weather are unlikely to become dehydrated or depleted of electrolytes. |
| Pack format | Check whether the product is a concentrate requiring water or a ready-to-drink can. Tesco and Sainsbury’s list canned soft-drink multipacks separately from bottled cordials. | If I’m taking an unopened single serving with me, a can fits that plan. If I choose cordial, I need water and a container to prepare it. |
| Nutrition and ingredients | Read the dilution directions, prepared-serving nutrition and ingredient list. Sainsbury’s specifies one part of its no-added-sugar lime cordial to four parts water and lists sulphites among its ingredients. | I want to know what is in the drink as prepared, especially if carbohydrate, sweeteners or an ingredient I avoid affects my choice. |
Tesco and Sainsbury’s list ready-to-drink canned soft drinks separately from bottled cordials. A can may meet a portability need without being the concentrate you intended to buy.
Decide which format you want before comparing packs, and read the product description rather than relying on flavour or packaging.
Sainsbury’s lists 2.1g carbohydrate per prepared 250ml serving of its no-added-sugar lime cordial. Fruit flavour alone tells you little about carbohydrate content.
Compare the prepared-serving nutrition with your intended use; do not treat the word ‘cordial’ as a fuel claim.
The American College of Sports Medicine says most people exercising for less than 60–90 minutes in normal weather are unlikely to become dehydrated or depleted of electrolytes. Heat, prolonged exercise and heavy sweating change the circumstances.
Consider duration, conditions and your fluid needs rather than treating a specialist drink as the default for every short run.
Cordial concentrate needs preparing before drinking. Sainsbury’s no-added-sugar lime cordial lists sodium metabisulphite (sulphites), which matters to shoppers avoiding that ingredient.
Follow the directions on the current pack and check its ingredient and allergen information before use.
Tesco and Waitrose list Robinsons bottled squash and cordial, including different bottle sizes and strengths.
Tesco lists own-label bottled squash in its squash and cordial range, while its adult soft-drinks range includes canned drinks.
Sainsbury’s no-added-sugar lime cordial is a bottled concentrate with directions to dilute one part cordial with four parts water.
M&S describes its cordials as drinks to dilute with still or sparkling water.
Waitrose lists bottled cordials from its own range and brands including Robinsons.
These options cover ready-to-drink canned multipacks and a bottled concentrate to dilute. Choose by the format you will use, then check the current pack’s nutrition and ingredients for your intended drink.

The can format suits a preference for unopened single servings. This is a soft drink rather than cordial concentrate; do not assume it provides run fuel or electrolyte replacement.

This ready-to-drink multipack is an option when individual servings matter more than buying cordial. It is a sparkling soft drink, so consider whether carbonation suits the occasion and check the current nutrition label if carbohydrate matters to you.

Choose the bottled concentrate if you want to prepare a flavoured drink with water rather than carry a ready-to-drink can. Follow the pack’s dilution directions, and check nutrition for the prepared drink and the current ingredient label before deciding whether it meets your needs.
Not solely because the distance is 5K. The American College of Sports Medicine says most people exercising for less than 60–90 minutes in normal weather are unlikely to become dehydrated or depleted of electrolytes; heat, prolonged exercise and heavy sweating call for a more individual fluid plan.
Do not assume it will. Sainsbury’s lists 2.1g carbohydrate and less than 0.5g sugars per prepared 250ml serving of its no-added-sugar lime cordial. Check the prepared-serving figures for the particular cordial you intend to drink.
Follow the bottle’s preparation directions instead. Sainsbury’s instructs shoppers to dilute its no-added-sugar lime cordial one part cordial to four parts water, while the NHS advises diluting squash and cordial well to reduce sugar content.
Read the current pack’s ingredient and allergen information for the exact drink. Sainsbury’s no-added-sugar lime cordial, for example, lists sodium metabisulphite (sulphites).
No: a ready-to-drink can and a cordial concentrate have different preparation requirements. Tesco and Sainsbury’s list canned soft drinks separately from bottled cordials, so check the product description before comparing their nutrition or convenience.
