Choose flavoured crisps as an occasional savoury snack, not as a direct replacement for your long-run carbohydrate and fluid plan. World Athletics’ endurance guidance describes planned carbohydrate intake for longer events; if you want crisps around training, compare the portion, carbohydrate, fat, salt and allergen information for the exact flavour.
If you are considering crisps instead of gels, drinks or other foods during a long run, start with your practised carbohydrate and fluid plan. World Athletics describes carbohydrate intake by event duration, while its published endurance-nutrition advice emphasises an individualised strategy rehearsed in training.
When the snack is separate from your main fuelling plan, the flavour you enjoy is only one consideration. Compare the bag size and its nutrition panel so that a single pack and a sharing bag are not treated as the same portion.
Salt declarations and ingredient lists differ between crisp flavours, including varieties from the same brand. Check the current pack for dietary claims and allergen or cross-contact statements rather than relying on a flavour name.
Decide whether you need food for a long run or a snack at another time; then compare crisp labels on the same portion basis.
| Priority | What to check | Your needs |
|---|---|---|
| Long-run fuelling | World Athletics lists 30–60 g carbohydrate per hour for events lasting 1–2.5 hours and up to 90 g per hour beyond 2.5 hours, subject to its guidance on carbohydrate types. Plan fluids separately and practise the approach during training. | For a long run, I need a carbohydrate and fluid plan I have rehearsed, rather than assuming a bag of crisps serves the same purpose as my usual fuel. |
| Portion and nutrition | Read carbohydrate and fat per 100 g for comparison, then check the figures for the amount you intend to eat. A 25 g individual bag and a sharing bag represent different portions. | I want a savoury snack away from the main fuelling window and need to know what one bag—or my portion of it—contains. |
| Salt by flavour | Compare salt per 100 g, then salt per bag or intended portion. Tyrrells lists 0.65 g/100 g for Lightly Sea Salted, KETTLE Chips lists 0.7 g/100 g for Lightly Salted, and McCoy’s lists 2.1 g/100 g for Salt & Malt Vinegar. | If salt matters to me, I want to compare the exact flavours on the same basis—not assume that “sea salt” or a stronger flavour tells me how much a portion contains. |
| Dietary suitability | Check the exact variety’s ingredients, dietary claims and allergen statements on the current pack. Walkers lists milk ingredients in Cheese & Onion; a plain-sounding flavour does not settle an allergy question. | Before choosing a flavour, I need its own label to meet my dietary requirements, including any relevant cross-contact warning. |
Crisps contain carbohydrate, but their label also includes fat, and a bag of crisps does not provide a fluid plan. World Athletics’ endurance guidance calls for carbohydrate intake matched to event duration and a strategy practised in training.
Keep the carbohydrate and fluid approach you have rehearsed at the centre of a long-run plan. Treat crisps as an optional snack unless your individual plan specifically accounts for them.
Manufacturer labels put Tyrrells Lightly Sea Salted at 0.65 g salt/100 g and McCoy’s Salt & Malt Vinegar at 2.1 g/100 g. The words on the front of a bag are no substitute for its nutrition panel.
Use the per-100-g figure to compare flavours, then check the amount in the portion you expect to eat.
Walkers Cheese & Onion lists milk-derived ingredients, while McCoy’s Salted lists possible milk, soya, gluten and mustard. Ingredient and cross-contact information can differ by variety.
Read the current ingredient and allergen statements for the precise product, particularly if you need to avoid an ingredient or possible cross-contact.
Pack formats in the reviewed ranges include individual bags and larger sharing bags. Nutrition figures per 100 g do not tell you what your chosen portion contains on their own.
Check the pack weight and per-serving information; if choosing a sharing bag, decide what portion you intend to have.
These examples show why it is worth comparing individual flavours and pack labels rather than making a decision from the brand name alone.
Its Lightly Sea Salted potato crisps provide a plain-flavour reference for comparing labels.
The Lightly Salted and Sea Salt & Balsamic Vinegar varieties illustrate differences within one range.
Ready Salted and Cheese & Onion offer a clear example of why flavour-specific details matter.
Sea Salted is a crinkle-cut option with both per-bag and per-100-g figures on its product page.
Its Salted and Salt & Malt Vinegar varieties have different declared salt levels.
Sea Salt and Sea Salt & Black Pepper provide another flavour-by-flavour label comparison.
These Joybuy options are flavoured or salted crisps to consider as occasional snacks around training, with sharing bags and individual-pack formats. Choose a pack by flavour, portion and its current ingredient and nutrition information—not as a replacement for planned long-run fuel.

A sweet-chilli flavoured option for an occasional savoury snack. The 150g bag is a sharing format, so check its serving information and current allergen label when deciding on a portion.
No image available
A lightly salted choice when you want a savoury snack rather than long-run fuel. KETTLE Chips declares 0.7 g salt and 53.7 g carbohydrate per 100 g for Lightly Salted. The manufacturer labels the variety gluten-free and suitable for vegans and vegetarians, but the retailer’s cross-contact information differs; check the current 130g pack carefully if you have an allergy.

Individual 25g bags offer a defined snack portion in two flavours. Walkers lists milk-derived ingredients in Cheese & Onion, so check each flavour’s current ingredient and allergen statement if dietary suitability matters.

Six individual 25g bags make it straightforward to check the nutrition for one snack pack. Walkers declares 0.34 g salt per 25g bag and 52 g carbohydrate per 100 g for Ready Salted. Check the current pack for its allergen and cross-contact statements.

A paprika-flavoured crisp for an occasional savoury snack. The 140g bag is a sharing format; check the current pack’s serving, ingredient and allergen information before choosing your portion.
Do not treat crisps as a direct replacement for a practised carbohydrate and fluid plan. World Athletics lists 30–60 g carbohydrate per hour for events lasting 1–2.5 hours and up to 90 g per hour beyond 2.5 hours, subject to its guidance on carbohydrate types. A crisp label may list carbohydrate, but it does not provide the same planned fuel-and-fluid approach.
Keep race-day food choices within a strategy you have practised in training. World Athletics’ published endurance-nutrition advice calls for an individualised, well-practised approach, so race day is not the occasion to find out whether an unfamiliar snack fits yours.
For the specified flavours, Tyrrells declares 0.65 g salt/100 g for Lightly Sea Salted and KETTLE Chips declares 0.7 g/100 g for Lightly Salted. Those figures compare manufacturer labels for particular products, not their suitability as running fuel. Check the portion you would eat as well as the per-100-g value.
No: check the exact flavour’s current pack. KETTLE Chips labels Lightly Salted gluten-free and suitable for vegans and vegetarians, as Seabrook does for Sea Salted, but other varieties can contain milk ingredients or carry cross-contact warnings. The retailer information for the listed Kettle Chips pack also differs from the manufacturer’s dietary claims, making the pack label particularly important for an allergy-sensitive purchase.
The NHS advises adults to have no more than 6 g of salt a day in total. A crisp label gives the amount in that product or portion; it does not establish an individual runner’s needs during exercise. Use the per-pack figure to understand the snack’s contribution, and follow any personalised advice you have been given.
