Who is this for?

Runners planning long-run fuel

If you are building a repeatable carbohydrate and fluid routine, the portion you can take at each planned interval matters more than the size of a sharing bag. The Australian Institute of Sport advises practising a plan that accounts for hydration and gut comfort.

Runners comparing sweets with sports fuel

Ordinary toffee contains carbohydrate, but that alone does not tell you how easily you can portion, carry and eat it while running. Compare the exact pack label with the serving information and directions on a gel, sports chew or drink.

Buyers checking ingredients and sweeteners

The Tesco listing for Werther's Original includes milk-derived ingredients and soya lecithin. Werther's Original Sugar Free Creamy Toffees list polyol sweeteners and carry a warning about excessive consumption, so check the precise product rather than treating all toffees alike.

What matters when choosing fuel?

Start with the carbohydrate portion and your planned intake schedule, then check how you will consume the product with fluids during a run. Practise the exact product and schedule in training rather than making the first trial on race day.

Priority What to check Your needs
Portioned carbohydrate Read the carbohydrate amount per serving and decide how each portion fits your schedule. The Australian Institute of Sport gives 30–60 g per hour for endurance exercise lasting 1–2.5 hours and up to 90 g per hour for ultra-endurance events lasting more than 2.5–3 hours; those figures are guidance tied to duration, not a target inferred from a bag's total contents. I want to know how much carbohydrate each portion provides, so I can practise a repeatable plan for the duration of my run.
Eating and drinking on the move Check the serving format and directions for fluids. The Australian Institute of Sport says a typical sports gel provides 20–30 g carbohydrate and that most gels should be taken with water or another dilute fluid. A portion needs to be practical for me to carry and consume at my running pace. I also need to practise how it fits with my fluid plan and gut comfort.
Sugar-free toffee Check carbohydrate per piece, the sweeteners and any pack warning. Werther's Original lists maltitol, isomalt and sorbitol syrup in its Sugar Free Creamy Toffees and warns that excessive consumption may produce laxative effects. If I am considering sugar-free sweets, I do not want the words “sugar free” to stand in for a checked fuelling portion or a product I have tried during training.
Ingredients and allergens Read the current label for the exact flavour and pack. Tesco lists milk-derived ingredients and soya lecithin for its Werther's Original 135 g bag; Marks & Spencer lists milk and soya ingredients in its Toffee Assortment and advises checking the pack because product details may change. With a relevant allergy or intolerance, I need to assess the product I will actually eat, not rely on a different flavour or an older listing.

Common buying mistakes

  • Using the whole bag as the fuelling calculation

    A bag's total carbohydrate does not show how much you will eat at each interval. The Australian Institute of Sport's endurance guidance relates intake to exercise duration and advises practising for hydration and gut comfort.

    Calculate portions from the nutrition label, then rehearse the product and schedule during training.

  • Choosing toffee as the main fuel to eat mid-run

    Tesco lists 8.4 g fat per 100 g for Werther's Original 135 g, while Marks & Spencer lists 18.8 g per 100 g for its chewy Toffee Assortment. Neither pack's confectionery format establishes a suitable timed intake plan.

    For planned long-run intake, compare labelled servings of gels, sports chews or drinks and practise consuming your choice while moving. Keep toffee as an optional sweet outside that plan.

  • Assuming sugar-free toffee avoids running-day problems

    Werther's Original Sugar Free Creamy Toffees contain polyol sweeteners, and the manufacturer warns that excessive consumption may produce laxative effects.

    Do not use sugar-free toffee as an untested replacement for a planned running fuel. Trial any new fuel during training.

  • Relying on an old ingredients listing

    Ingredients matter when avoiding milk or soya, and Marks & Spencer warns that its product information may change.

    Check the current ingredients and allergen declaration on the precise pack before eating it or taking it to an event.

Relevant brand references

These examples help distinguish ordinary toffee packs and their labels from portioned running fuel; a brand's inclusion does not make its confectionery a marathon-fuelling recommendation.

Werther's Original

Tesco lists a 135 g Werther's Original bag, while the manufacturer separately lists Sugar Free Creamy Toffees. Check which product you have: their ingredients and nutrition information are not interchangeable.

  • Tesco lists 86.9 g carbohydrate per 100 g for the 135 g bag.
  • That bag also lists 8.4 g fat per 100 g and milk-derived and soya ingredients; its bag-level figures do not set out a running intake schedule.
  • The manufacturer warns that excessive consumption of its Sugar Free Creamy Toffees may produce laxative effects.

M&S

Marks & Spencer's 200 g Toffee Assortment is a chewy confectionery pack containing several flavours.

  • Marks & Spencer lists 74.4 g carbohydrate per 100 g, giving buyers a figure to use when reading the pack.
  • The assortment also lists 18.8 g fat per 100 g and milk and soya ingredients. Marks & Spencer advises reading the current label because product details may change.

Tesco

Tesco lists Werther's Original and a Tesco 175 g toffee product among traditional confectionery.

  • Its Werther's Original listing provides per-100 g nutrition and ingredient information that can inform a pack comparison.
  • A traditional-sweets listing does not establish a toffee's suitability for eating during a marathon. Check the current label of the product you choose.

Joybuy gel options

These gels represent the portioned sports-fuel route for runners comparing it with a toffee sharing bag. Check each pack's identity and directions, and practise your chosen fuel within your running and fluid routine.

Applied Nutrition Endurance Elite Tri-Carb Energy Gel, Apple Burst, pack of 20

Applied Nutrition Endurance Elite Tri-Carb Energy Gel, Apple Burst (20 gels)

This portioned gel is an option for a long-run carbohydrate schedule rather than a toffee sharing bag. The listing states 40 g carbohydrate per gel; check how that amount fits your practised intake plan and the current pack directions. The listing also states age and other use restrictions, which should be checked on the pack before use.

Science in Sport GO Isotonic gel, Fruit Salad, 60 ml, pack of 12

Science in Sport GO Isotonic Gel, Fruit Salad, 60 ml (12 packs)

This single-pack gel format is worth comparing if you want portions to carry on a long run. The listing title and description use different product names, so confirm the exact identity, carbohydrate amount and fluid directions on the current pack before building it into a fuelling plan. Practise using the product during training.

Questions about toffee and running fuel

Can a toffee sharing bag replace gels on a marathon long run?

A toffee sharing bag is not a useful foundation for a timed fuelling plan: choose labelled portions you can practise alongside your fluid routine instead. The Australian Institute of Sport relates carbohydrate guidance to exercise duration, giving 30–60 g per hour for 1–2.5 hours of endurance exercise and up to 90 g per hour for ultra-endurance events lasting more than 2.5–3 hours. The right practised plan also needs to account for individual gut comfort.

How much carbohydrate is in a typical sports gel?

The Australian Institute of Sport says a typical gel provides 20–30 g carbohydrate per sachet. Read the exact product label when calculating portions, because the amount can differ between gels.

Should I take water with a running gel?

The Australian Institute of Sport advises taking most gels with water or another dilute fluid to reduce the concentration of carbohydrate consumed and the risk of gut upset. Follow the directions for your exact gel, including any different instructions for a product labelled isotonic, and practise it with your fluid plan.

Are sugar-free toffees a better choice for fuelling a run?

Do not assume that sugar-free toffee provides a suitable running-fuel portion. Werther's Original lists maltitol, isomalt and sorbitol syrup in its Sugar Free Creamy Toffees and warns that excessive consumption may produce laxative effects. Check the carbohydrate amount and ingredients of the exact product instead of substituting it for a fuel you have practised.

What should I check if I need to avoid milk or soya?

Read the current ingredients and allergen declaration for the exact toffee and flavour before eating it. Tesco's Werther's Original listing includes milk-derived ingredients and soya lecithin, while Marks & Spencer lists milk and soya ingredients in its Toffee Assortment and notes that product details may change.
