For a snack 60–90 minutes before a 5k, a sharing bag of potato crisps is a poor match for University College London Hospitals NHS Foundation Trust’s pre-workout guidance, which calls for carbohydrate and minimal fat. If the crisps are for a bowl after the run or well before the start, choose by pack size, salt per 100g and the exact flavour’s ingredients and allergen statement.
If you are choosing a snack 60–90 minutes before a 5k, consider its fat content as well as its carbohydrate. University College London Hospitals NHS Foundation Trust’s pre-workout guidance calls for carbohydrate and minimal fat.
A sharing bag can be divided into portions after the run. Check the weight and stated servings so the bag fits the number of people eating, then check the label for salt and allergens.
Salt values, ingredients and dietary declarations vary by flavour. Read the current pack for the particular bag you intend to serve, especially when someone needs to avoid an allergen.
Decide when the crisps will be eaten, then compare the pack and its label rather than relying on the flavour name.
| Priority | What to check | Your needs |
|---|---|---|
| Timing | For food 60–90 minutes before exercise, compare carbohydrate and fat per serving. University College London Hospitals NHS Foundation Trust advises a pre-workout snack containing carbohydrate and minimal fat. | If I am eating shortly before the start, I want a familiar snack that fits that guidance rather than using a crisp sharing bag as my main fuel. |
| Salt | Compare salt per 100g, then the stated serving size. NHS food-label guidance describes 0.3g or less per 100g as low and more than 1.5g per 100g as high; those thresholds refer to the food, not the whole bag. | For a shared bowl, I want to know how much salt is in the portion I am likely to eat, not just whether the front says “lightly salted”. |
| Bag size | Check the net weight and servings per pack. Tyrrells lists five servings in its Naked 150g bag; Kettle Chips lists a 130g Lightly Salted bag in its selection box. | I am putting crisps into bowls after the run and want a pack size that suits the group rather than a single-serve bag. |
| Dietary details | Read the ingredients, allergen statement and any dietary declaration on the exact flavour. ASDA lists milk in Real Hand Cooked Strong Cheese & Onion 150g; Tyrrells gives its Naked bag a may-contain-milk warning. | Before serving guests, I need to check the particular bag against their dietary requirements instead of assuming another flavour has the same ingredients. |
Timing and the full nutrition panel matter. University College London Hospitals NHS Foundation Trust advises minimal fat in a snack 60–90 minutes before exercise, while Tyrrells lists 8.9g fat in a 30g serving of Naked crisps.
For food close to the start, choose a familiar option that fits the pre-workout guidance. Keep the sharing bag for another eating occasion.
A flavour description does not tell you how much salt is in your portion, particularly when people take different amounts from a sharing bag.
Compare the per-100g figures between bags, then use the pack’s serving information to assess the portion you expect to eat. NHS food-label thresholds provide context for the per-100g figure.
Declarations belong to particular products: Tyrrells Naked carries a may-contain-milk warning, while ASDA lists milk as an ingredient in Real Hand Cooked Strong Cheese & Onion.
Check the current ingredients and allergen statement for each flavour before putting it into a shared bowl.
These named products illustrate label differences; a brand name alone does not establish the pack size, ingredients or nutrition of another flavour.
Tyrrells lists Naked (no salt) as a 150g bag with five servings, making it a reference point for a plainly seasoned sharing bowl.
Kettle Chips lists a 130g Lightly Salted bag within its sharing selection box.
ASDA lists Real Hand Cooked Strong Cheese & Onion as a 150g sharing bag.
Pipers Anglesey Sea Salt offers a named plain-flavour product for comparing nutrition labels.
Walkers Lightly Salted and Oven Baked Sea Salt are distinct products whose labels can be compared with a sharing bag.
Seabrook is a UK crisp brand to consider if you are browsing crinkle-cut options.
These three 130g and 150g potato crisp bags suit a shared bowl after a 5k or another eating occasion away from the start. They are different products from Tyrrells Naked, so its no-salt label and nutrition figures must not be applied to them.

The 130g format is an option for a post-run sharing bowl. Kettle Chips lists potatoes, rapeseed and sunflower oils, and sea salt for its Lightly Salted version; check the current bag’s allergen statement before serving guests.

This 150g bag provides a lightly sea-salted option for a shared bowl. It is not Tyrrells Naked (no salt); compare the salt per 100g and read the allergen statement on this exact bag.

The 150g Furrows bag offers a sea-salt flavour and crinkle-cut crisps for sharing after the run. Check its own nutrition panel and allergen statement rather than using figures from another Tyrrells product.
A sharing bag is a poor match for a snack eaten 60–90 minutes before the start. University College London Hospitals NHS Foundation Trust advises carbohydrate and minimal fat for a pre-workout snack, while its listed 30g serving of Tyrrells Naked crisps contains 8.9g fat. Choose food you already know suits you near the start, and save the crisps for another occasion.
Compare salt per 100g first, then check the stated serving size against the amount you expect to eat. NHS food-label guidance describes 0.3g or less per 100g as low and more than 1.5g per 100g as high; the flavour name alone does not provide that comparison.
Read the current ingredients and allergen statement for each exact flavour. Tyrrells Naked carries a may-contain-milk warning, and ASDA lists milk in Real Hand Cooked Strong Cheese & Onion even though that bag is marked suitable for vegetarians and gluten-free. Do not transfer a declaration from one flavour to another.
