Casual 5K and parkrun runners
If you are deciding whether to eat before a run, consider when you last ate and how long you expect to be active. A familiar breakfast or snack is a different purchase from a tube of mints or a chocolate gift box.
Who is choosing?
Shoppers putting mints in a run bag
Choose between an ordinary sweet and a sugar-free mint for the flavour and format you want. The labelled three-mint portions of Polo Original and Polo Sugar Free differ in sugars and energy; neither is a replacement for a meal or planned snack.
Gift buyers who also run 5K events
A box of chocolates can be chosen for gifting or sharing without treating it as pre-run food. Check the exact pack’s ingredients and allergens against the recipient’s needs.
What matters before a 5K?
Decide whether you need food for the run first. Then choose mints or boxed chocolates on their own terms, rather than using the confectionery purchase to answer that question.
| Priority | What to check | Your needs |
|---|---|---|
| Run duration | Consider how long you expect to be active and when you last ate. University College London Hospitals NHS Foundation Trust says snacks for energy during activity may be needed when exercise lasts longer than 60 minutes; shorter activity can still call for an individual plan where low blood glucose is a concern. | I want to know whether to take food at all, rather than buying a sweet simply because I am running a 5K. |
| Time before running | Choose food you know you tolerate. The UK Sports Institute suggests porridge about an hour before a run, or a banana if there is not time for breakfast. University College London Hospitals NHS Foundation Trust describes a pre-workout snack 60–90 minutes beforehand as containing carbohydrate and protein with minimal fat. | If I want to eat before setting off, I need an option that fits the time available and my usual routine. |
| Mint choice | Compare the stated serving and sugar content, not just the words “sugar free”. Tesco lists three Polo Original mints at 4.4 g carbohydrate, including 4.3 g sugars, and 18 kcal; three Polo Sugar Free mints have 4.3 g carbohydrate, less than 0.5 g sugars and 10 kcal. | I am choosing a portable mint or small sweet, not expecting a few mints to stand in for pre-run food. |
| Chocolate gift suitability | Read the exact box’s current ingredients, allergens and per-100g nutrition. Tesco lists milk, barley, soya and wheat for its 110 g Maltesers gift box, with 24 g fat and 53 g sugars per 100 g. | For a gift or something to share, I care about what the recipient can eat and which chocolates they would enjoy. |
What should you avoid assuming?
-
“A sugary chocolate box is ready-made pre-run food”
Chocolate can contain substantial fat as well as sugar: Tesco lists 24 g fat per 100 g for its 110 g Maltesers gift box. That differs from University College London Hospitals NHS Foundation Trust’s guidance to keep fat minimal in a pre-workout snack.
Choose a chocolate box for gifting or a treat. If you want food before running, consider a familiar option and the time you have before setting off.
-
“A tube of mints replaces a snack”
Tesco lists three Polo Original mints at 18 kcal and 4.4 g carbohydrate, and three Polo Sugar Free mints at 10 kcal. Those small portions are not a planned meal or substantial snack.
Choose mints for their flavour or portable format, and make any pre-run food decision separately.
-
“A familiar chocolate box needs no allergen check”
Assortments can contain ingredients that matter to a recipient. For example, Tesco’s listing for a 110 g Maltesers gift box identifies milk, barley, soya and wheat.
Read the current ingredient and allergen declaration on the exact pack before gifting or sharing it.
-
“General 5K advice covers glucose-management needs”
Cambridge University Hospitals NHS Foundation Trust advises people taking insulin or sulphonylureas to consider how exercise affects their blood glucose. A general snack suggestion cannot account for an individual medication and glucose-management plan.
Use the exercise plan agreed with your diabetes care team rather than relying on mints or chocolates alone or changing medication based on general running advice.

Common questions
Do I need to carry mints or chocolate during a 5K?
Not simply because the distance is 5K. University College London Hospitals NHS Foundation Trust says snacks for energy during exercise may be needed for activity lasting longer than 60 minutes, while shorter activity can call for snacks for low-blood-glucose prevention or treatment. Consider your expected duration, prior food intake and individual medical needs.
What could I eat about an hour before a 5K?
Choose a familiar food you tolerate. The UK Sports Institute suggests porridge about an hour before a run, or a banana when there is not time for a full breakfast. Your usual routine and the time available matter more than buying confectionery specifically for the run.
Can Polo mints replace a pre-run snack?
No: a few mints are a small sweet, not a substantial snack. Tesco lists three Polo Original mints at 4.4 g carbohydrate and 18 kcal; three Polo Sugar Free mints have 4.3 g carbohydrate, less than 0.5 g sugars and 10 kcal. Choose either version as a mint, not as your main food before running.
Is a box of chocolates suitable as a gift for a runner?
It can be a gift or something to share without being presented as running fuel. Check the exact pack against the recipient’s dietary needs: for example, Tesco’s 110 g Maltesers gift box listing identifies milk, barley, soya and wheat.
What if I take insulin or another glucose-lowering medicine?
Follow your individual exercise and glucose-management plan rather than using general 5K snack advice to decide how much carbohydrate to take. Cambridge University Hospitals NHS Foundation Trust advises people taking insulin or sulphonylureas to be aware of exercise effects on blood glucose. Discuss changes to your medication plan with your diabetes care team.
