For activity lasting 60–120 minutes, University College London Hospitals NHS Foundation Trust says carbohydrate-only snacks can be suitable. Choose a bar for use during a run by checking its carbohydrate per serving and trying it in training; a protein-containing multipack may make more sense as a snack before or after a session. Before buying several bars, check the portion count, best-before date and ingredients against how you plan to use them.
If you want something portable during a run, distinguish carbohydrate-focused snacks from bars chosen mainly for their protein content. University College London Hospitals NHS Foundation Trust says carbohydrate-only snacks can be suitable for activity lasting 60–120 minutes.
Individually wrapped bars can be convenient to keep at home or in a bag. Choose the pack for the time you expect to eat the bars, rather than assuming a snack for after training will also suit you while running.
Check the ingredients and allergen information on the exact flavour and pack before committing to several bars. A brand’s wider range does not establish the suitability of every product it makes.
Start with when you intend to eat the bar, then assess whether its portions and ingredients work for your training plans.
| Priority | What to check | Your needs |
|---|---|---|
| Training moment | Check carbohydrate per serving for use during a run. For snacks before or after training, check the full nutrition panel rather than selecting by protein alone. Try unfamiliar foods in training. | For a 60–120-minute run, I want a snack I can eat comfortably while moving. For another time of day, a protein-containing bar may serve a different purpose. |
| Usable pack size | Compare bar count, weight per bar and individually wrapped portions. Check the best-before date against how often you expect to use them. | A larger box only works for me if I can use its portions before the date on the pack. |
| Ingredients and allergens | Read the current label for each flavour, including allergen and ‘may contain’ statements. Check any vegan or gluten-free claim on the exact product. | I need bars that meet my dietary requirements, not just a familiar brand name or a claim made for another flavour. |
A bar selected for its protein may not match the carbohydrate-focused snack you want during a longer session. University College London Hospitals NHS Foundation Trust says carbohydrate-only snacks can be suitable for activity lasting 60–120 minutes.
Decide when you will eat it, compare carbohydrate per serving, and practise with the food during training before relying on it for an important run.
Pack count alone does not tell you whether every portion fits your plans before its best-before date.
Check the number and size of the bars, then match the pack to the sessions and snacks you have planned.
An ingredient or allergen warning can make a whole multipack unsuitable for someone with a relevant dietary restriction. A bar that feels comfortable as an everyday snack may also feel different while running.
Read the current label for the exact flavour and try a smaller pack during ordinary training before buying a larger quantity.
These ranges contain different kinds of snacks; assess the specific bar or pack rather than treating a brand as one training-fuel option.
The range includes Crunchy, Sweet & Salty Nut and Protein bars. Its Protein Peanut & Chocolate Big Pack contains eight 40 g bars, according to Nature Valley UK.

For a bar you might take on a run, compare the carbohydrate per serving on this oat bar’s label with your plan and try it during training first. The pack contains three 50 g bars; check its current allergen information before use.
Not automatically. University College London Hospitals NHS Foundation Trust says carbohydrate-only snacks can be suitable for activity lasting 60–120 minutes. Check a prospective bar’s carbohydrate per serving and try it during ordinary training before relying on it for an important run.
It can be an option as a pre-training snack, but choose it for the time available before you run and how you tolerate its portion and ingredients. Do not assume that being labelled a protein bar also makes it the right food to eat during the session.
Compare the number and size of the bars with how often you expect to eat them, then check the pack’s best-before date. If a flavour or texture is unfamiliar, trying a smaller pack first also lets you assess it during training.
Read the current label for the exact flavour, including its ingredients, allergen statements and nutrition per bar. A brand-level dietary claim or an older listing is not a substitute for checking the pack you intend to use.
