For a 5k, treat potato crisps as an optional savoury snack rather than your main pre-run fuel. If you want crisps, a familiar single-serve baked pack makes the portion easier to judge, but check its carbohydrate, fat and allergens for the flavour you will eat. The British Dietetic Association advises a low-fat, carbohydrate-led snack or light meal before exercise; University of Birmingham Sport & Fitness also recommends keeping fat and fibre low when eating one to two hours before a run.
If you want crisps alongside a lower-calorie eating plan, compare the calories in the amount you will actually eat. An individual bag and a sharing bag are different portions, even when their per-100 g labels look similar.
If you plan to eat within one to two hours of running, consider whether crisps are simply a snack or whether you need a carbohydrate-led meal or snack. University of Birmingham Sport & Fitness advises high-carbohydrate choices that are low in fat and fibre during that pre-run window.
A plain-sounding crisp flavour does not establish what its ingredients or precautionary allergen statement will say. Check the current pack for the exact flavour, particularly when buying for someone with a food allergy or dietary restriction.
Decide first whether you need pre-run food or just want a savoury snack. Then compare the portion you would eat, not only the figures per 100 g.
Consider when: You want a familiar, portioned savoury snack rather than your main pre-run food.
Keep in mind: Walkers Oven Baked Sea Salt provides 16 g carbohydrate per 22 g pack, so check whether a crisp pack answers your fuelling need.
Consider when: You want an ordinary crisp snack and lower-fat pre-run food is not the purpose of the purchase.
Keep in mind: The named standard crisps with comparable manufacturer labels have more fat per 100 g than Walkers Oven Baked Sea Salt.
Consider when: You are choosing food to provide carbohydrate before the run, especially close to the start.
Keep in mind: Choose a familiar option that fits your timing; it will not necessarily satisfy a wish for something salty and crunchy.
| Priority | What to check | Your needs |
|---|---|---|
| Pre-run timing | Check when you will eat and whether the food is intended as a snack or pre-run fuel. University of Birmingham Sport & Fitness advises high-carbohydrate, low-fat and low-fibre choices particularly one to two hours before running. | I am eating close to the start and want to choose a familiar food that fits that timing. |
| Whole-pack calories | Read the kcal figure for the bag or amount you intend to eat, then use per-100 g values to compare products on the same basis. Walkers UK lists 96 kcal per 22 g Oven Baked Sea Salt pack; Seabrook Crisps lists 164 kcal per 31.8 g Sea Salted bag. | A small bag suits what I want to eat; I do not want to mistake a sharing bag for one portion. |
| Carbohydrate | Check grams per portion, not just per 100 g. Walkers UK lists 16 g carbohydrate in a 22 g Oven Baked Sea Salt pack. The British Dietetic Association advises a carbohydrate-led snack or light meal before exercise. | If I need pre-run food, I want to know whether this portion answers that need or is simply an extra snack. |
| Fat and fibre | Check both values for the specific product and portion. Walkers UK lists 2.8 g fat per 22 g Oven Baked Sea Salt pack; Seabrook Crisps lists 9.7 g per 31.8 g Sea Salted bag. University of Birmingham Sport & Fitness advises keeping fat and fibre low in the one-to-two-hour pre-run window. | I would rather keep a higher-fat crisp snack for another time if I am eating shortly before the run. |
| Ingredients and allergens | Read the current ingredients, dietary-suitability wording and may-contain statement for the exact flavour. Joybuy’s Walkers Oven Baked Sea Salt listing names possible milk, wheat, soya, mustard and other gluten-containing-cereal exposure. | I need the pack I buy to fit my dietary requirements, not just to have a plain-sounding flavour. |
Walkers UK lists 16 g carbohydrate in a 22 g Oven Baked Sea Salt pack. A portioned crisp snack and a carbohydrate-led pre-run meal or snack serve different purposes.
If you are buying food specifically for before the run, consider a familiar, low-fat carbohydrate-led snack or light meal first. Treat crisps as optional.
Walkers UK lists 96 kcal for a 22 g Oven Baked Sea Salt pack, while Seabrook Crisps lists 164 kcal for its 31.8 g Sea Salted bag. Those are calories for different-sized portions, not an equal-weight comparison.
Use per-100 g figures to compare products, then return to the label for the amount you plan to eat.
Manufacturer labels for REAL Sea Salt, KETTLE Lightly Salted and Seabrook Sea Salted list around 30 g fat per 100 g. University of Birmingham Sport & Fitness advises lower-fat food particularly one to two hours before running.
If you want standard crisps, consider them as a separate snack occasion rather than assuming their carbohydrate content makes them a suitable immediate pre-run choice.
Tyrrells says its Lightly Sea Salted crisps may contain milk, and Joybuy’s Walkers Oven Baked Sea Salt listing names several possible allergens.
Check the current pack’s ingredients and allergen statement for the exact product and flavour before buying.
These examples describe named products and ranges; their labels should not be applied to every flavour a brand makes.
Oven Baked Sea Salt is an individually portioned baked crisp to compare when you want a savoury snack.
Lightly Sea Salted is a hand-cooked potato crisp offered in 40 g, 150 g and 600 g packs, according to Tyrrells.
Lightly Salted is a standard potato-crisp option for comparison by its labelled nutrition.
Sea Salted is a crinkle-cut crisp with nutrition stated for a 31.8 g bag.
Anglesey Sea Salt is a potato-crisp option for shoppers comparing sea-salt flavours.
Sea Salt comes in 35 g and 150 g bags, according to REAL Hand Cooked Crisps.
These options include portioned Walkers baked crisps and two other savoury snacks. PopChips and Jacob’s Crinklys should not be treated as interchangeable with the potato crisps discussed above; check each product’s ingredients and nutrition for the portion you intend to eat.

The six individual bags make it straightforward to choose a 22 g portion when you want a savoury snack. Check nutrition and allergens for the particular flavour you take; the published Sea Salt figures should not be applied to every flavour in a variety pack.

Each bag is a defined 22 g portion if you prefer Cheese & Onion to Sea Salt. Check this flavour’s own nutrition and allergen statement rather than using figures for Walkers Oven Baked Sea Salt.

The 85 g bag requires you to decide how much you intend to eat before comparing it with an individual crisp pack. Check the ingredients, allergens and nutrition for that amount rather than assuming a serving figure describes the whole bag.

This is a portioned savoury snack, with six 23 g packs, rather than a traditional potato crisp. Its product information identifies wheat and milk allergens; check the current pack and compare its own nutrition before choosing it for a pre-run snack.
Do not assume a small crisp pack meets your pre-run food needs. The British Dietetic Association advises a low-fat, carbohydrate-led snack or light meal before exercise, while Walkers UK lists 16 g carbohydrate in a 22 g Oven Baked Sea Salt pack. A crisp pack can instead be an optional savoury snack if it is familiar to you.
Not on calories alone. Check carbohydrate, fat, fibre, portion size and how the food fits your timing. University of Birmingham Sport & Fitness recommends high-carbohydrate choices that are low in fat and fibre particularly one to two hours before running; a small crisp pack may not answer the same need as a pre-run snack or light meal.
Base that decision on how long you expect to exercise and what you have tried in training, rather than treating crisps as necessary for every 5k. The British Dietetic Association says carbohydrate during exercise can enhance performance when exercising hard for longer than an hour; that guidance does not establish a need for crisps during a shorter run.
No. Check the current pack for the exact product. Tyrrells says Lightly Sea Salted may contain milk, while Joybuy’s Walkers Oven Baked Sea Salt listing names possible milk, wheat, soya, mustard and other gluten-containing-cereal exposure.
