Mini marshmallows can be a portionable sweet if you want a small amount of carbohydrate around a run and have tried the product and timing in training; they are not a requirement for every 5K. World Athletics lists 0–20 g of carbohydrate per hour as an option for 45–75 minutes of endurance exercise, while the British Dietetic Association says people following a general fitness programme can meet their carbohydrate needs through their normal diet. Choose the format by the portion you want to measure, the ingredients you can use and whether you want loose mini pieces or twists.
Loose mini pieces may appeal if you would rather measure a little confectionery than carry a full snack. For a 45–75 minute endurance effort, World Athletics presents a small carbohydrate amount as an option, not an automatic need for a 5K.
If you are considering marshmallows before or during a run, try the particular product, amount and timing in training first. A familiar routine matters more to this decision than choosing a sweet solely for its carbohydrate figure.
Waitrose and Tesco list pork gelatine in their plain mini marshmallows. M&S lists a vegan alternative, but warns that it is not suitable for people with milk, nut or peanut allergy; check the current pack for the product you intend to use.
Start with the run and your usual eating routine, then decide whether a measured sweet adds anything useful for you. If it does, compare the portion, shape and ingredients rather than treating all marshmallows as interchangeable.
| Priority | What to check | Your needs |
|---|---|---|
| Run and routine | Consider how long the effort will take and what you normally eat beforehand. World Athletics gives 0–20 g carbohydrate per hour as an option for 45–75 minutes of endurance exercise; the British Dietetic Association says a normal diet can meet the needs of a general fitness programme. | If my 5K is short or follows a normal meal, I may not want a separate sweet for the run. |
| Portion | Use carbohydrate per 100 g or a declared serving to work out the amount you plan to carry. Tesco lists 3.8 g carbohydrate per 5 g of its mini marshmallows; Tesco lists 19.3 g per declared 25 g serving of Barratt Mini Flumps. | I want to measure a small amount, rather than assume a handful or a whole bag is one portion. |
| Piece shape | Check whether the pack contains loose mini pieces, twists or regular marshmallows. A stated serving weight can help with portioning, but does not make twists the same shape as loose minis. | Small individual pieces matter to me if I plan to pack only a few; otherwise, a twist or regular marshmallow may suit the portion I have in mind. |
| Ingredients | Read the current ingredients and allergen information. Waitrose and Tesco mini products list pork gelatine; M&S labels its regular marshmallows vegan but gives separate milk, nut and peanut allergy warnings. | My dietary requirements come before piece size. I need to check the exact pack rather than rely on the word ‘vegan’ for allergy suitability. |
| Timing | Try the exact product and amount during training if you intend to eat it near a run. For general exercise planning, the British Dietetic Association describes a light meal or carbohydrate snack two to three hours beforehand as an option. | Before an event, I would rather follow a food and timing routine I already know than introduce an unfamiliar sweet. |
A 5K distance alone does not tell you how long you will be exercising or whether you want extra carbohydrate. World Athletics’ optional 0–20 g-per-hour range applies to 45–75 minutes of endurance exercise, not to every 5K.
Consider the expected duration and your usual eating routine before buying a run-day portion.
The listed Waitrose and Tesco mini products contain pork gelatine. The M&S vegan alternative carries milk, nut and peanut allergy warnings, so vegan labelling does not settle the allergy question.
Check the ingredients, allergen information and dietary suitability statement on the current pack before purchase and use.
A carbohydrate figure tells you what a portion supplies, not whether its taste, texture or timing will suit your run-day routine.
If you plan to use marshmallows near a run, try the same product and measured amount in training first.
These product lines show how loose minis, twists and a vegan non-mini option differ; their inclusion does not mean they are Joybuy products.
Its Mini Pink & White Marshmallows come as loose mini pieces in a 150 g bag.
Tesco Mini Marshmallows are pink-and-white mini pieces in a 60 g bag.
Barratt Mini Flumps are marshmallow twists in a 150 g bag, rather than loose mini pieces.
Its Vegan Marshmallows offer a regular-marshmallow format when avoiding animal-derived ingredients matters more than mini size.
The Joybuy option here is a bag of marshmallow twists for shoppers willing to check piece size and measure a portion by weight. If loose, bite-size minis are essential, confirm the twist dimensions before choosing it.

For a planned portion around training, the listed 80 g carbohydrate per 100 g lets you work from the weight you choose. This is a 140 g bag of twists; check the piece size if you specifically want bite-size minis, and weigh your portion rather than assuming a particular number of pieces. The description identifies beef gelatine and labels it halal, so check the current pack if that designation is essential; the gelatine also makes it unsuitable for a vegetarian or vegan requirement.
No, not automatically. World Athletics lists 0–20 g carbohydrate per hour as an option for 45–75 minutes of endurance exercise, while the British Dietetic Association says a normal diet can meet the carbohydrate needs of a general fitness programme. Consider your expected run duration and usual meals before deciding whether to carry a sweet.
Use the pack’s carbohydrate figure and a measured weight or declared serving, rather than guessing from a handful. Tesco lists 3.8 g carbohydrate per 5 g for its mini marshmallows, Waitrose lists 77.3 g per 100 g for its minis, and Tesco lists 19.3 g per 25 g serving for Barratt Mini Flumps. Check the current label for the pack you buy.
Use a product, amount and timing that you have tried in training rather than introducing a new sweet just before an event. For general exercise planning, the British Dietetic Association describes a light meal or carbohydrate snack two to three hours beforehand as an option; choose a routine that fits the session.
Check the particular product: Waitrose and Tesco list pork gelatine in their mini marshmallows, while M&S labels its regular marshmallows vegan but says they are not suitable for people with milk, nut or peanut allergy. Read the current ingredients and allergen information on the pack rather than inferring suitability from the product category or vegan label.
