Runners packing for long training runs
Look at carbohydrate per bar and whether the wrapping and portion work for what you plan to carry. Try the bar while training rather than assuming one bar covers a whole run.
Who is choosing these bars?
Runners concerned about pre-run stomach discomfort
Compare fat and fibre as well as carbohydrate, and consider when you will eat the bar. The UK Sports Institute advises lower-fat, lower-fibre foods when minimising gastrointestinal distress around training is important.
Runners choosing a snack after training
A protein-and-nut bar may suit a between-meal or post-run snack instead of a carbohydrate-led running snack. Nature Valley UK lists 10.2g protein and 11g carbohydrate per 40g Protein Peanut & Chocolate bar; check its allergens before choosing it.
What should you compare?
Start with the portion you would actually pack, then compare its nutrition and ingredients for the point in training when you intend to eat it.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate per bar | Compare carbohydrate per serving and the bar’s weight, rather than relying on a front-of-pack description. Kellogg’s UK lists 25g per 37g Nutri-Grain Apple bar and 18g per 25g Frosties Cereal Milk Bar. | I want to know what each bar contributes to the food I pack for a run. |
| Fat, fibre and timing | Read fat and fibre per bar, then try the portion at the intended time in training. The UK Sports Institute advises lower-fat, lower-fibre foods when gastrointestinal distress is a concern. | Before a run, I want a bar I know I can tolerate at that time. |
| Protein-led snacks | Compare protein alongside carbohydrate, fat and fibre. Nature Valley UK lists 10.2g protein, 11g carbohydrate, 11.3g fat and 4.4g fibre per 40g Protein Peanut & Chocolate bar. | For a snack after training or between meals, protein matters more to my choice than it does for the bar I pack to eat during a run. |
| Allergens and ingredients | Read the current pack’s ingredients, allergen declaration and any ‘may contain’ statement. A gluten-free label does not answer questions about peanuts, soya or milk. | I need to check whether this exact flavour and pack meet my dietary requirements. |
| Pack format | Check the number of bars, the weight of each portion and whether each is wrapped separately. | I want portions I can pack for the training sessions I have planned. |
What can catch you out?

Choosing by ‘protein’ or ‘energy’ wording alone
Those words do not tell you the carbohydrate in one bar. Kellogg’s UK lists 25g carbohydrate for Nutri-Grain Apple, while Nature Valley UK lists 11g for Protein Peanut & Chocolate.
Compare carbohydrate, fat, fibre and protein per bar for the occasion when you plan to eat it.

Assuming a high-fibre flapjack suits the time just before a run
Graze describes its Oat Boost flapjacks as high-fibre oat products. The UK Sports Institute advises lower-fibre foods when minimising gastrointestinal distress around training matters.
Try the exact product, portion and timing in training before packing it for a key session.

Overlooking allergens on a familiar-looking bar
Nature Valley’s gluten-free-labelled Protein Peanut & Chocolate bar contains peanuts, soya and milk and may contain tree nuts. The Kellogg’s examples also have cereal, milk or soya allergens.
Check the current pack’s ingredient list and allergen declaration for every flavour you choose.

Planning around an old Alpen flavour
Alpen Muesli lists several former bar varieties as no longer being made.
Confirm the exact bar’s current availability and pack label before making it a regular part of your training bag.

Common questions
Should a protein cereal bar be my main running snack?
Compare carbohydrate per bar before choosing it for that purpose. Nature Valley UK lists 11g carbohydrate and 10.2g protein per 40g Protein Peanut & Chocolate bar, while Kellogg’s UK lists 25g carbohydrate per 37g Nutri-Grain Apple bar. The Nature Valley bar may fit a protein-led snack after training or between meals instead.
What if bars cause stomach discomfort before a run?
Compare fat and fibre, then try the exact bar, portion and timing during training. The UK Sports Institute advises lower-fat, lower-fibre foods when minimising gastrointestinal distress around training is important; avoid making an untested bar part of a key session.
Are oat and cereal bars automatically gluten free?
No. Check the exact pack: Nature Valley labels its Protein Peanut & Chocolate bar gluten free, while Kellogg’s Nutri-Grain Apple contains wheat, oats and barley, and its Frosties Cereal Milk Bar contains barley and may contain gluten from other cereals.
How should I check allergens in a mixed grab bag?
Read the current ingredient and allergen statement, including ‘may contain’ information, for each product and flavour. Nature Valley’s Protein Peanut & Chocolate bar, for example, contains peanuts, soya and milk and may contain tree nuts.
Can I plan around an Alpen bar flavour I used before?
Check that exact flavour before adding it to a regular training bag. Alpen Muesli lists several former bar varieties as no longer being made, so confirm current availability and read the current pack label.
