Marathon trainees planning long-run fuel
If you are deciding what to take during a long run, plan an ingestible carbohydrate source rather than relying on sugar-free gum. World Athletics gives carbohydrate-intake guidance by session duration.
Who is this for?
Runners who want portioned gum after training
Separate small packs can be divided between bags or shared without opening every pack. Sainsbury’s describes its Extra Peppermint 5 x 10 multipack as five individual packs for sharing or stocking up.
Frequent gum users checking ingredients
If you need to check soya, sweeteners or phenylalanine warnings, read the current label for the particular gum you choose. The Extra and Airwaves multipacks listed by Sainsbury’s include SOYA lecithin and carry warnings about excessive consumption and phenylalanine.
What should you check?
Decide what you need during the run first; then choose a gum format for sharing or chewing afterwards.
| Priority | What to check | Your needs |
|---|---|---|
| Fuel for the run | Match carbohydrate intake to the session duration. World Athletics specifies 30–60 g per hour for 1–2.5 hours and up to 90 g per hour beyond 2.5 hours, using carbohydrate drinks, gels or confectionery as applicable. Do not treat carbohydrate listed as polyols on sugar-free gum as a fuelling plan. | For a long run, I need a carbohydrate plan I can practise during training, separate from any gum I carry. |
| Shareable portions | Check how many individual packs and pieces are included. Sainsbury’s describes its Extra Peppermint 5 x 10 multipack as five separate packs. | I want to leave portions in different bags or share them after training without opening all the gum at once. |
| Ingredients and warnings | Read the current pack for allergens, sweeteners and warnings. The Extra and Airwaves listings at Sainsbury’s include SOYA lecithin and warnings about phenylalanine and excessive consumption; formulations can differ. | If an ingredient matters to me, I need to check this flavour and pack rather than rely on another gum’s label. |
| Fluids and mouth comfort | Keep gum separate from your drinking plan. Gum does not provide the fluids you need to drink; NHS Specialist Pharmacy Service also lists frequent sips of cool drinks among measures for dry mouth. | When my mouth feels dry after activity, I do not want chewing gum to take the place of a drink. |
Buying pitfalls
-
Reading the gum’s carbohydrate figure as endurance fuel
Sugar-free gum can list carbohydrate largely as polyols. That figure does not show that chewing the gum will meet the intake described in World Athletics’ endurance guidance.
Practise a separate plan using suitable carbohydrate foods or drinks for the length of your run; choose gum for chewing, not as its replacement.
-
Treating a sharing pack as an unlimited supply
The Extra and Airwaves multipacks listed by Sainsbury’s warn that excessive consumption may produce laxative effects. GOV.UK specifies a laxative-effect warning for foods with more than 10% added polyols.
Read the warning on your pack, particularly before using an unfamiliar amount around a long run.
-
Assuming sugar-free means free from other ingredients of concern
Checked Extra and Airwaves listings include SOYA lecithin and carry a phenylalanine warning. Sugar-free describes the sugar content, not the full ingredient list.
Check the current label whenever you change flavour or pack format, especially if you need to avoid a listed ingredient.
-
Using gum instead of a drink
Chewing gum does not provide hydration, even if you choose to chew it when your mouth feels dry.
Carry and use your planned fluids; keep gum as a separate, optional item.

Frequently asked questions
Can sugar-free gum fuel a 1–2.5-hour marathon-training run?
Do not use it as your primary fuel. World Athletics recommends 30–60 g of carbohydrate per hour for endurance activity of that duration and identifies carbohydrate drinks, gels or confectionery as options; keep sugar-free gum separate from a practised fuelling plan.
When is a 5 x 10 gum multipack useful for a runner?
It suits dividing gum into small packs for sharing or keeping in different bags after training. Sainsbury’s describes its Extra Peppermint 5 x 10 multipack as five individual packs designed for sharing or stocking up.
Can gum replace a drink when my mouth feels dry?
No. Gum does not provide hydration, so keep to your planned fluids. NHS Specialist Pharmacy Service also lists frequent sips of cool drinks among measures for dry mouth.
What should I check on a large sugar-free gum pack?
Read the current label for ingredients, allergens and warnings. The Extra and Airwaves multipacks listed by Sainsbury’s include SOYA lecithin and carry warnings about phenylalanine and excessive consumption; ingredients can vary between products.
Should I reread the label when buying the same gum again?
Yes, particularly if an allergen, sweetener or warning matters to you. Sainsbury’s advises shoppers that product ingredients can change and to read the product label rather than rely solely on its online listing.
