For a typical 5K or parkrun, there is no need to buy a box of biscuits or chocolates as dedicated run fuel: the UK Sports Institute advises against fuelling a parkrun as though it were a marathon. A small, familiar custard-cream portion can be an optional pre-run snack; if the purpose is a gift, choose the biscuit or chocolate format the recipient would actually want and check the pack’s ingredients and allergens.
Who is this choice for?
Recreational 5K and parkrun runners
If you are considering biscuits specifically for a run, start with your usual pre-run eating routine. The UK Sports Institute says a parkrun does not call for marathon-style fuelling; a familiar biscuit is an optional snack, not a requirement.
People buying a runner a gift
Decide whether the recipient would prefer ordinary custard creams, a chocolate-coated biscuit or a chocolate gift. Tesco describes standard custard creams as vanilla-filled sandwich biscuits, while M&S describes its chocolate-coated version as a different, more chocolate-led treat.
Shoppers checking allergens
Check the exact packet before buying for someone who avoids particular ingredients. The McVitie’s Tasties and Asda custard-cream examples list wheat and milk; Asda also lists several possible cross-contact allergens.
What matters when choosing?
Separate the run-day decision from the gift decision, then compare the serving and label of the exact product you might buy.
Usual 5K routine
Choose when: The runner has eaten as they normally would before a 5K and does not want an extra snack.
Keep in mind: UK Sports Institute advice that parkrun does not need marathon-style fuelling does not rule out an individual preference for a snack.
Optional biscuit snack
Choose when: The runner wants a small portion of a food they already know suits their pre-run routine.
Keep in mind: A custard cream is an ordinary biscuit, not a specialised running product; check the serving rather than treating the pack as one portion.
Gift or post-run treat
Choose when: Giving a treat matters more than choosing something to eat before the run.
Keep in mind: Chocolate-coated custard creams remain biscuits, while a chocolate assortment is a different gift format; neither should be presented as necessary 5K fuel.

What to check |
Your needs |
| Purpose |
Is this for eating before a usual 5K, or for giving afterwards? The UK Sports Institute says parkrun does not require marathon-style fuelling. |
I want to know whether a snack is needed at all, rather than buying a larger pack because it looks like run fuel. |
| Portion |
Compare nutrition per biscuit as well as per 100 g. Sainsbury’s lists 8.6 g carbohydrate, 2.4 g fat and 1.2 g saturates per biscuit for its Custard Creams 200 g. |
If I choose an optional biscuit, I want to judge the portion I might eat, not the size of the packet. |
| Gift format |
Check whether the item is a vanilla-filled biscuit, a chocolate-coated biscuit or chocolates in a gift pack. Tesco and M&S describe distinct custard-cream formats. |
I’m buying a treat for a runner and want the contents to match what they would expect from the gift. |
| Ingredients |
Read the current packet for ingredients and allergens. Asda lists wheat and milk in its Custard Creams 400 g and warns of possible rye, barley, oats and sesame. |
Before I share or give the food, I need to check the exact product against the recipient’s requirements. |
Buying mistakes to avoid
-
Treating a whole pack as necessary 5K fuel
For a typical parkrun, the UK Sports Institute says runners do not need to fuel as if preparing for a marathon. A gift-sized pack does not establish an appropriate pre-run serving.
Start with the runner’s normal routine. If they want a biscuit, consider a small portion of something familiar rather than using the packet size as a guide.
-
Looking at calories without checking the serving
Sainsbury’s lists 59 kcal, 2.4 g fat and 1.2 g saturates per biscuit for its Custard Creams 200 g. A per-biscuit figure answers a different question from a per-100 g label.
Read both measures on the product you are buying so you can judge the portion and compare its composition with other options.
-
Assuming every custard cream is a chocolate gift
Tesco’s standard custard creams are vanilla-filled sandwich biscuits. M&S separately describes a chocolate-coated variant; coating does not turn every custard cream into boxed chocolates.
Check the contents and packaging if the recipient is expecting chocolates, rather than relying on the words “custard cream” alone.
-
Relying on a previous pack’s allergen label
McVitie’s Tasties and Asda custard-cream examples list wheat and milk. Ingredients and warnings need to be checked for the exact product being shared.
Read the current packet before buying or gifting it, particularly when the recipient has specified ingredients they must avoid.
Custard cream brand references
These UK grocery examples illustrate differences in biscuit format and labelling; they are separate from the Joybuy products below.
McVitie’s
McVitie’s Tasties Custard Cream Biscuits 300 g are a standard custard-cream option listed by Iceland Foods.
- A familiar biscuit format for a snack or household treat.
- Iceland’s ingredient listing includes wheat and milk; check the current pack for the recipient.
Tesco
Tesco describes its Custard Cream Biscuits 400 g as sandwich biscuits with a vanilla-flavour filling.
- A clearly identified standard biscuit format.
- A standard custard-cream pack is not, by itself, a boxed-chocolate gift.
Sainsbury’s
Sainsbury’s Custard Creams 200 g have published per-biscuit nutrition figures.
- Sainsbury’s lists 59 kcal, 8.6 g carbohydrate, 2.4 g fat and 1.2 g saturates per biscuit, allowing a portion-level comparison.
- Those figures describe this Sainsbury’s biscuit, not every custard cream or a recommended running portion.
Asda
Asda lists an own-label Custard Creams 400 g pack.
- The listing identifies the standard biscuit format and declares allergens.
- Asda lists wheat and milk and warns that the biscuits may contain rye, barley, oats and sesame; check the packet before sharing.
M&S
M&S describes a milk-chocolate-coated custard cream as a chocolate-led biscuit treat.
- The coating distinguishes this variant from a standard vanilla-filled custard cream when choosing a gift.
- M&S’s description is about the treat’s format, not its suitability as running fuel; check the exact variant and label.

Questions about 5K snacks and gifts
Do I need custard creams to fuel a 5K?
No special custard-cream purchase is needed for a typical 5K. The UK Sports Institute says parkrun does not require marathon-style fuelling. A small snack remains an individual choice if it already fits the runner’s usual routine.
Are custard creams a box of chocolates?
Standard custard creams are not boxed chocolates: Tesco describes them as vanilla-filled sandwich biscuits. A chocolate-coated custard cream is another biscuit format, so check the actual contents and packaging when buying a chocolate gift.
What should I check before eating a custard cream ahead of a run?
Check the exact biscuit’s ingredients and per-biscuit nutrition, and choose a portion that fits your familiar pre-run routine. For comparison, Sainsbury’s lists 8.6 g carbohydrate, 2.4 g fat and 1.2 g saturates per biscuit for its Custard Creams 200 g; those figures do not describe other products.
Can I give standard custard creams to someone avoiding wheat or milk?
Do not assume they will be suitable. The McVitie’s Tasties and Asda examples list wheat and milk, so read the current ingredients and allergen information on the exact packet before giving it to the recipient.
