For a run lasting more than an hour, plan carbohydrate intake around a format you can portion and use while running rather than relying on mini toffee as your sole fuel. The Gatorade Sports Science Institute gives a 30–90 g carbohydrate-per-hour range for exercise lasting more than 60 minutes; Werther’s Original lists just 4.5 g per Butter Candy, making it a small supplementary sweet to assess in training, not a complete hourly plan.
Who needs to think about the format?
Runners planning longer training sessions
For exercise lasting more than 60 minutes, the Gatorade Sports Science Institute gives a during-exercise carbohydrate range of 30–90 g per hour, depending on the situation. A repeatable plan matters more than whether a sweet looks small enough to carry.
Runners considering a pocket sweet as backup
Werther’s Original lists 4.5 g carbohydrate in each 5.2 g Butter Candy. That figure makes a supplementary portion countable, but several sweets would be needed to make a substantial contribution while moving.
Runners checking ingredients and sugar-free options
Tesco lists milk and soya for Werther’s Chewy Toffees. Werther’s Original also warns that excessive consumption of its sugar-free sweets may have laxative effects. Check the current pack against your own dietary requirements rather than assuming that a small or sugar-free sweet will suit a run.
What should you check before choosing?
Start with the carbohydrate amount you intend to use, then consider whether the portion, packaging and ingredients work during your run.
| Priority | What to check | Your needs |
| Hourly intake |
Compare carbohydrate per piece or serving with your planned hourly amount. The Gatorade Sports Science Institute gives a 30–90 g-per-hour range for exercise lasting more than 60 minutes; the appropriate intake depends on the situation. |
I want to know how each portion contributes to my plan, rather than count on a bag of sweets to provide an unspecified amount. |
| Portion handling |
Werther’s Original lists 4.5 g carbohydrate per Butter Candy; seven pieces provide 31.5 g. Consider how you would carry, open and consume the portions while running. |
A small sweet could be a supplementary option, but I need a format I can use repeatedly if it forms part of my planned intake. |
| Sugar-free sweets |
Read the sweetener information and pack warning. Werther’s Original warns that excessive consumption of its sugar-free range may have laxative effects. |
I do not want to mistake “sugar-free” for a measured carbohydrate-fuel option during a long run. |
| Ingredients |
Check the current ingredient and allergen label for the exact product. Tesco lists milk and soya for Werther’s Chewy Toffees and advises that food formulations can change. |
If milk or soya matters to me, I need to assess the particular pack before putting it in my running kit. |
Common buying mistakes
-
Treating one mini sweet as an hourly fuel plan
Werther’s Original states that one Butter Candy provides 4.5 g carbohydrate. Seven provide 31.5 g, at the lower end of the Gatorade Sports Science Institute’s 30–90 g-per-hour range for exercise lasting more than 60 minutes; handling seven hard sweets is a separate practical consideration.
Calculate portions from the pack’s carbohydrate figure before a session. If you need deliberate intake throughout a long run, choose a format whose labelled serving you can use in a repeatable plan.
-
Picking sugar-free toffee as a fuel substitute
Werther’s Original warns that excessive consumption of its sugar-free sweets may have laxative effects. “Sugar-free” does not tell you that a sweet will supply the carbohydrate in your running plan.
Do not use sugar-free Werther’s in place of a planned carbohydrate serving. Check the current pack warning if buying it as confectionery.
-
Overlooking ingredients in a small sweet
Tesco lists milk and soya in Werther’s Chewy Toffees. The size of a sweet does not change the importance of its ingredients for someone who needs to avoid them.
Read the current label for the exact variant you intend to carry, particularly if you have an allergy or intolerance.
-
Assuming “mini bites” means running portions
Marks & Spencer presents its Mini Bites as shareable cake bites. The word “mini” describes size, not a carbohydrate amount per piece or a way to schedule intake during a run.
Compare the nutrition information and serving size with your own plan instead of choosing by the product name alone.
Brands and retailers to compare
These confectionery references help distinguish formats; a retailer’s range does not establish that a particular sweet suits endurance fuelling.
Werther’s Original
Its Butter Candies, chewy toffees and sugar-free sweets raise different portioning and ingredient questions.
- The brand gives 4.5 g carbohydrate per 5.2 g Butter Candy, allowing a per-piece calculation.
- The brand warns that excessive consumption of its sugar-free sweets may have laxative effects; check ingredients for the exact variant.
Tesco
Its Werther’s product listings can help distinguish hard sweets from chewy toffee.
- The Chewy Toffees listing gives nutrition per 100 g and identifies milk and soya.
- Tesco advises that ingredients and nutrition information can change, so use the current pack for the final check.
Sainsbury’s
Its toffee range includes assorted Sainsbury’s toffees, Werther’s Chewy Toffee and Walker’s Nonsuch products.
- The range offers conventional toffee formats to compare.
- Check the exact product’s nutrition and packaging before deciding whether its portions work for a run.
Waitrose
Its toffee, fudge and nougat category is a place to compare confectionery formats.
- The category includes products such as clotted cream fudge and caramel fudge.
- A place in the confectionery category does not establish a per-piece running-fuel portion.
M&S
Its Mini Bites are presented as shareable cake bites rather than measured running-fuel servings.
- The small-bite format provides another type of portion to assess from its label.
- Do not use the word “mini” as a substitute for checking carbohydrate per serving.
A Joybuy gel option for planned intake
This gel represents the measured sports-fuel route for longer training sessions, rather than a choice between mini toffees. Check its carbohydrate per serving against the intake you intend to plan.

Questions about toffee and running
Can Werther’s Butter Candies be my main fuel for a long run?
They are difficult to use as a sole, repeatable hourly plan. Werther’s Original lists 4.5 g carbohydrate per sweet, so seven provide 31.5 g; the Gatorade Sports Science Institute gives a 30–90 g-per-hour range for exercise lasting more than 60 minutes. Consider both the number of sweets you would need and whether you can handle them while running.
Is sugar-free toffee a better option for running?
Do not treat sugar-free toffee as a substitute for a planned carbohydrate serving. Werther’s Original warns that excessive consumption of its sugar-free sweets may have laxative effects and advises people with diabetes to consult a medical practitioner about suitability.
Should I check the wrapper if I need to avoid milk or soya?
Yes. Tesco identifies milk and soya in its Werther’s Chewy Toffees listing and advises that food formulations can change. Read the current ingredient and allergen information for the exact product you intend to carry.
Does a bag of chewy toffee make portion planning easier?
Not necessarily. Tesco lists 71.8 g carbohydrate per 100 g for Werther’s Chewy Toffees, but an hourly plan needs a usable amount for the portion you will actually eat. Check the pack’s serving information and consider how you would measure and consume those portions during a run.
