For a prolonged training run, plan a carbohydrate-and-fluid strategy rather than relying on potato crisps as your main fuel. A 2015 sports-nutrition article indexed by PubMed advises 30–60g of carbohydrate per hour for exercise lasting 1–2.5 hours, while the Tesco and ASDA ready-salted listings each give around 13–14g per 25g bag. If you want crisps as a savoury snack around training, compare pack sizes and portions, then check the nutrition and allergen information on the exact product.
If a run calls for a planned carbohydrate-and-fluid intake, a small bag of crisps is not a straightforward substitute. The Tesco and ASDA ready-salted listings give 13.7g and 13g of carbohydrate respectively per 25g bag.
If crisps are for snacking rather than fuelling a run, compare the number and size of portions in a multipack with a sharing bag. Choose a format you can use as intended, without treating pack size as evidence of fuelling suitability.
If milk, gluten or vegan labelling matters to your choice, check the exact pack. The reviewed Tyrrells Lightly Sea Salted product, for example, carries a may-contain-milk statement despite its gluten-free claim.
Decide whether you are buying fuel for a run or a snack for another time. That distinction changes which details on the pack matter most.
| Priority | What to check | Your needs |
|---|---|---|
| Run fuelling | Check carbohydrate per portion against your planned intake for the session. A 2015 sports-nutrition article indexed by PubMed advises 30–60g per hour for exercise lasting 1–2.5 hours; Tesco and ASDA list 13.7g and 13g respectively per 25g ready-salted bag. | For a prolonged run, I need a carbohydrate-and-fluid plan I can practise in training, not a small snack bag treated as a complete hourly portion. |
| Pack format | Compare total pack weight, the number of bags and grams per portion. A sharing bag and a multipack of individual bags serve different snacking habits. | I want to know whether individual bags or a sharing pack will fit when I plan to eat the crisps. |
| Label details | Read salt per stated serving and check that serving size before comparing packs. Check ingredients, dietary claims and may-contain statements on the exact product. | If salt or an ingredient restriction matters to me, the current label tells me more than words such as “lightly salted” or “plain”. |
Multiple small bags would be needed to reach the 30–60g hourly carbohydrate range cited for 1–2.5 hours of exercise in the 2015 sports-nutrition article indexed by PubMed. The reviewed Tesco and ASDA 25g bags also contain 7.3g and 9g of fat respectively per bag.
Plan and practise what you will eat and drink during longer runs; keep crisps in their role as a snack if you enjoy them.
A gluten-free claim does not rule out a separate milk warning: the reviewed Tyrrells Lightly Sea Salted pack may contain milk. Salt declarations also use stated serving sizes, which can differ between packs.
Read the current ingredients, allergen statement and nutrition panel for the exact flavour and pack size before buying.
These references describe specific reviewed products, not every pack made by each brand. Check the label for the variant you choose.
The reviewed Ready Salted 14 x 25g multipack has individual bags for ordinary snacking.
The reviewed Lightly Salted product comes as a 5 x 25g multipack.
The reviewed Lightly Sea Salted product is a 150g sharing bag with a stated 30g serving.
The reviewed Sea Salted product is a 6 x 25g multipack.
The reviewed Anglesey Sea Salt product is a 150g sharing bag.
These are crisp and potato-snack formats for snacking around training, including salted multipacks, a mixed-flavour pack and larger portions. They are not presented as primary fuel for a marathon run.

Six individual 25g bags suit someone looking for ready-salted crisps as a snack. Check this pack’s own nutrition and allergen label rather than applying figures from a different Walkers multipack.
No image available
This six-pack offers individual 24g bags for snacking when you prefer the Salt & Shake format. Check the pack’s ingredients and seasoning instructions if salt or allergens matter to you.

This 12 x 25g multipack combines two flavours for ordinary snacking, so it is not a plain-salted-only choice. Check the ingredients for each flavour separately, particularly if you avoid milk.

The 40g tubes are a different portion format from the 25g crisp bags discussed above. Read this product’s own ingredients and nutrition panel before comparing a tube with a bag.

This 150g sharing bag offers a flavoured alternative to the plain salted multipacks. If dietary claims affect your choice, check the current pack label and its stated serving size.
They are not a practical primary choice for a planned long-run fuelling strategy. A 2015 sports-nutrition article indexed by PubMed advises 30–60g carbohydrate per hour for exercise lasting 1–2.5 hours, whereas Tesco and ASDA list about 13–14g in each reviewed 25g ready-salted bag. Practise a carbohydrate-and-fluid plan during training rather than relying on those bags to make up an hourly intake.
No. Read the numerical salt declaration and its serving size on the exact pack. Tesco lists 0.20g salt per 30g serving for the reviewed Tyrrells Lightly Sea Salted bag and 0.33g per 25g bag for the reviewed Seabrook Sea Salted multipack; those serving sizes differ.
Check the current ingredients and may-contain statement for the exact flavour before eating it. The reviewed Tyrrells Lightly Sea Salted product may contain milk, so its gluten-free claim does not answer a milk-allergy question. Do not carry an allergen statement over to another pack or variant.
Follow the storage, best-before and after-opening instructions on the pack you buy. Keep unopened packs cool and dry; for a sharing bag, check its instructions once opened rather than assuming they match those for individually sealed bags.
