Choose cordial for a flavoured drink, but do not assume that a can or multipack provides fuel for a long run. The British Dietetic Association says carbohydrate intake during hard exercise lasting more than an hour can enhance performance; for those sessions, check the prepared drink’s carbohydrate content and plan it alongside anything else you intend to consume.
If you want a drink to contribute to your fuelling plan, compare carbohydrate in the drink as prepared, not just its flavour or pack format. The British Dietetic Association identifies carbohydrate intake as relevant to hard exercise lasting more than an hour.
If flavour is the main reason for buying cordial, a diluted squash may meet that preference without being part of a measured carbohydrate plan. Check the particular product’s nutrition panel and dilution instructions.
Ingredients differ between cordials. ASDA Groceries lists barley and sulphur dioxide/sulphites for Robinsons Fruit & Barley Peach; check the current label of the exact flavour you intend to buy.
Decide whether you want a flavoured drink or one that contributes a known amount of carbohydrate during a run, then compare labels at the strength you will actually drink.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Check grams per 100ml of prepared drink and how much your other drinks or food contribute. The British Dietetic Association says carbohydrate intake during hard exercise lasting more than an hour can enhance performance. | For a long run, I want to know what the drink contributes to my wider fuelling plan rather than rely on the pack format. |
| Drink formulation | Check whether the label states carbohydrate and electrolyte content. NHS Tayside describes isotonic drinks as containing electrolytes and 4–8g carbohydrate per 100ml; that description does not establish the composition of a particular cordial. | If I want both fluid and a known carbohydrate content during exercise, flavour alone will not tell me whether a drink fits. |
| Dilution and sugar | Follow the product’s dilution ratio and compare nutrition at that strength. ASDA Groceries lists 4.1g carbohydrate per 100ml diluted for Robinsons Lime & Mint; its listing describes Robinsons Fruit & Barley Peach as no added sugar with negligible carbohydrate. | I may want a flavoured drink without relying on it for carbohydrate, or I may want to account for the carbohydrate a sugared cordial provides. |
| Ingredients | Read the current ingredients and allergen statement for the exact flavour. ASDA Groceries lists barley and sulphur dioxide/sulphites in Robinsons Fruit & Barley Peach and warns that product information can change. | When I need to avoid an ingredient, I cannot assume every flavour in a familiar range has the same recipe. |
| Pack format | Confirm the container type, pack count and volume per container. A convenient multipack does not establish the drink’s carbohydrate or electrolyte content. | If I specifically want cans, I need to check that the pack contains cans rather than bottles before ordering. |
Pack size and container type say nothing about how much carbohydrate the prepared drink supplies. NHS Tayside describes isotonic drinks as containing electrolytes and 4–8g carbohydrate per 100ml; a cordial needs to be assessed from its own label.
For a long session, check the drink’s prepared nutrition information and account for any other drinks or food in the plan you practise during training.
ASDA Groceries describes Robinsons Fruit & Barley Peach as no added sugar with negligible carbohydrate. Its flavour does not make it a substantial carbohydrate source.
Choose it for a flavoured drink if that is what you want; if you plan to consume carbohydrate during a run, identify where that carbohydrate will come from.
Changing a cordial’s dilution changes the concentration of the prepared drink. Ingredients also vary: ASDA Groceries lists barley and sulphur dioxide/sulphites for Robinsons Fruit & Barley Peach.
Follow the exact product’s mixing instructions, check its current label and follow any storage directions after opening.
These are cordial references for comparing formats and labels, not a list of marathon-fuelling products or Joybuy stock.
The range includes fruit cordial and no-added-sugar squash for dilution with water.
M&S Food lists cordials intended for dilution with still or sparkling water.
Waitrose lists own-label cordials alongside branded products.
These multipacks are sports drinks for shoppers considering a drink for longer training sessions. Both listed packs contain bottles, not cordial cans; check each product’s nutrition label against your own fuelling plan.

A three-bottle electrolyte-drink pack to consider if you want bottles rather than cordial cans for training. Check the nutrition label to establish its contribution to your plan, and practise your choice during training.

A 24-bottle sports-drink pack rather than a cordial-can multipack. Use the product’s nutrition label when planning what to drink during a run, and practise the plan in training.
Not automatically. A cordial’s contribution depends on its recipe and dilution: ASDA Groceries lists 4.1g carbohydrate and 0.02g salt per 100ml diluted for Robinsons Lime & Mint, while NHS Tayside describes isotonic drinks as containing electrolytes and 4–8g carbohydrate per 100ml. Check the exact drink and practise any wider fuelling plan during training.
Do not count on it without checking the label. ASDA Groceries describes Robinsons Fruit & Barley Peach as no added sugar with negligible carbohydrate, so it should not be counted as a substantial carbohydrate source in a fuelling plan.
Follow the ratio on the exact product. ASDA Groceries specifies one part Robinsons Lime & Mint concentrate to six parts water; changing that ratio changes the prepared drink’s concentration.
Check the current label for the flavour you are buying. ASDA Groceries lists barley and sulphur dioxide/sulphites in Robinsons Fruit & Barley Peach, and notes that product and allergy information can change.
Check the pack you receive as well. ASDA Groceries advises reading the label because ingredients, nutrition and allergy information may change.
