Runners who prefer a chewable sweet
A small, labelled piece could add variety to selected training runs if you can count its carbohydrate and are comfortable eating it while moving.
Who might consider mini fudge?
Runners practising an in-run food plan
A training run gives you a chance to try the portion, timing and chewing involved before deciding whether to carry fudge on a more demanding run. Check the exact product’s ingredients and fat content as part of that choice.
People choosing a sweet around training
If you want fudge as a treat rather than a measured in-run portion, an individually weighed bite matters less. A sharing pack still needs portioning if you intend to count its carbohydrate towards a run plan.
What matters when choosing it for a run?
Decide whether fudge is an occasional addition or whether you need a repeatable hourly carbohydrate plan; then compare the nutrition information for the portion you would actually carry.
A measured sweet addition
Consider it when: You can count the carbohydrate in each portion and have practised eating that format during training.
Trade-off: Several confectionery pieces may be needed to make a substantial carbohydrate contribution, bringing their declared fat and the practical task of chewing them too.
A structured endurance-fuel plan
Consider it when: You need to plan carbohydrate intake across a long or demanding session rather than rely on an occasional sweet.
Trade-off: You still need to practise the products, amounts and timing you intend to use; a plan does not establish that any one product will suit you.
| Priority | What to check | Your needs |
|---|---|---|
| Countable carbohydrate | Find carbohydrate per bar or bite, not just per 100 g. Tesco Groceries lists 10 g per 13.5 g Cadbury Fudge Treat Size bar and 8.8 g per Tesco Chocolate Fudge Mini Bite. A review in Ned Tijdschr Geneeskd advises 30–60 g carbohydrate per hour for exercise lasting 1–2.5 hours; its guidance is not a serving instruction for either sweet. | I want to know what the portion I carry contributes, rather than judge it by how small it looks. |
| Format and practice | Compare the declared fat alongside carbohydrate: Tesco Groceries lists 2.1 g fat per Cadbury treat-size bar and 2.6 g per Tesco mini bite. Try the intended amount and timing during training, including the practicalities of chewing while running. | A solid sweet appeals to me, but I need to find out whether I can comfortably eat the amount I have planned during a run. |
| Ingredients and allergens | Read the ingredients and allergen information on the current pack. GOV.UK guidance says the ingredients list for pre-packed food must emphasise the allergens required to be declared; product formulations and warnings differ. | If I avoid particular ingredients, I need the information for this exact flavour and pack, not an assumption based on the word “fudge”. |
Common mistakes to avoid
-
Counting one mini bite as an hourly portion
Tesco Groceries lists 8.8 g carbohydrate per Tesco Chocolate Fudge Mini Bite and 7.2 g per approximately 12 g Thorntons brownie bite. Each is a contribution, not the same amount as the 30–60 g per hour discussed for 1–2.5 hours of exercise in the Ned Tijdschr Geneeskd review.
Calculate the carbohydrate in the number of pieces you intend to take, then practise that amount and its timing on a training run.
-
Treating every “fudge bite” as the same food
The formats include a treat-size bar, a chocolate fudge mini bite and a brownie bite containing fudge pieces. Their declared portions and nutrition values differ.
Compare the exact product name and the label’s unit of measurement before counting pieces towards a plan.
-
Assuming plain-looking confectionery has simple ingredients
For example, Marks & Spencer lists barley, wheat, milk and soya for its Sweet and Salty Pretzel Fudge Mini Bites and states that they are not suitable for people with a nut or peanut allergy.
Read the current pack’s ingredients and allergen statement, especially when changing flavour or format.
Brands and formats to compare
These examples illustrate why the declared serving matters more than a shared “fudge” description; they do not establish that every product from a brand has the same ingredients or nutrition.
Cadbury
Tesco Groceries lists both a Fudge Treat Size bar with nutrition per 13.5 g bar and a separate Fudge Bites product with nutrition per portion.
- The treat-size bar is declared at 10 g carbohydrate and 2.1 g fat per bar.
- Do not interchange the bar’s figures with Fudge Bites: Tesco lists 19 g carbohydrate and 4.2 g fat per declared portion for that different product.
Tesco
Tesco Chocolate Fudge Mini Bites has nutrition declared for one mini bite.
- Tesco lists 8.8 g carbohydrate and 2.6 g fat per bite, allowing the pieces to be counted.
- The product carries a may-contain peanuts and nuts warning; check the current pack if that affects your choice.
Thorntons
Thorntons Chocolate Fudge Brownie Bites is a brownie-bite format, not a piece of plain fudge.
- Tesco Groceries declares 7.2 g carbohydrate and 2.5 g fat per approximately 12 g serving.
- Check that this brownie format, rather than a plain fudge piece, is what you want to carry and eat during a run.
M&S
Sweet and Salty Pretzel Fudge Mini Bites combines pretzel and fudge in a sharing format.
- Marks & Spencer declares 70.8 g carbohydrate and 19.0 g fat per 100 g, which can be used when weighing a portion.
- A per-bite weight is needed to count intake by pieces. Marks & Spencer lists barley, wheat, milk and soya and says the product is not suitable for people with a nut or peanut allergy.
Cornish Fudge Co.
The Cornish Fudge catalogue lists Clotted Cream Fudge and Caramel & Seasalt Fudge in 150 g bag formats.
- A bag format may suit someone choosing fudge as a sweet around training.
- For measured in-run portions, check the particular pack’s nutrition declaration and weigh what you intend to carry.

Cadbury Fudge Minis 100 g
A mini fudge format to consider if you prefer a solid sweet around training. The pack is 100 g; check the current pack for the carbohydrate in the portion you intend to carry, as well as its ingredients and allergen information. Practise eating that portion during training before considering it for a run.
Questions about mini fudge and training
How many mini fudge pieces provide 30 g of carbohydrate?
It depends on the exact product and its declared unit. Tesco Groceries lists 10 g carbohydrate per Cadbury Fudge Treat Size bar, so three bars provide 30 g; its Tesco Chocolate Fudge Mini Bites have 8.8 g per bite, so four provide 35.2 g. Those amounts do not tell you whether either food will be comfortable to eat while running.
Can mini fudge be my main marathon fuel?
Mini fudge can add carbohydrate, but do not assume a few pieces will cover a long run’s planned intake. A review in Ned Tijdschr Geneeskd advises 30–60 g carbohydrate per hour for exercise lasting 1–2.5 hours; for longer high-intensity exercise, it says well-trained endurance athletes can metabolise up to 90 g per hour when glucose and fructose are combined. Work out what your chosen portions contribute and practise your fuelling plan in training.
What should I check if I avoid certain ingredients?
Read the current pack’s ingredients and allergen statement for the exact product. GOV.UK guidance says the ingredients list for pre-packed food must emphasise allergens required to be declared; the listed fudge and fudge-bite formats differ in ingredients and warnings, so one product’s label cannot stand in for another’s.
