Who might choose dark chocolate around a 5k?

Runners who want an optional treat

If your 5k is a shorter activity, you may want a familiar piece of Fairtrade dark chocolate before or after it without treating chocolate as compulsory fuel. University College London Hospitals NHS Foundation Trust says snacks for shorter activities may only be needed to prevent or treat hypoglycaemia.

Runners planning a snack near the start

If meal timing or an established exercise plan means you need a carbohydrate snack shortly before running, consider whether dark chocolate fits that purpose and whether you have tolerated it before. Follow your individual plan if you manage blood glucose.

Shoppers checking the exact Fairtrade claim

If Fairtrade ingredients are a requirement, check the bar and variant rather than assuming a brand-wide ethical-sourcing statement applies. The Fairtrade Foundation distinguishes a mark covering all certifiable ingredients from a Fairtrade Sourced Ingredient mark identifying particular ingredients.

What matters when choosing a bar?

Decide whether you want an optional chocolate snack or a closer-to-start carbohydrate top-up, then check the Fairtrade wording and the exact pack.

Priority What to check Your needs
Snack timing Consider when you last ate, how long the run will take and whether you need a snack at all. University College London Hospitals NHS Foundation Trust says snacks for shorter activities may only be needed to prevent or treat hypoglycaemia. I want chocolate as an optional treat around a short run, rather than something I have to eat during every 5k.
Carbohydrate and fat Read both values per 100g and consider your intended portion and timing. Divine Chocolate lists 31.7g carbohydrate and 44.3g fat per 100g for its plain 70% bar; those figures alone do not establish how a different bar will suit you. If I need a snack close to the start, I want to choose it for that purpose rather than assume a higher cocoa percentage means better run fuel.
Fairtrade coverage Check the claim on the exact product. The Fairtrade Foundation says the classic FAIRTRADE Mark covers ingredients that can be Fairtrade-certified; a Fairtrade Sourced Ingredient mark identifies the named ingredient instead. I want to know whether the claim covers certifiable ingredients across the bar or a specified ingredient such as cocoa.
Allergens and variant Read the current ingredients and allergen statement, including may-contain warnings. Check again when switching flavour or cocoa percentage; a vegan recipe does not by itself establish milk-allergy suitability. Before eating a different bar, I need to check its own label rather than rely on what another dark-chocolate product says.

What should you avoid assuming?

  • Every 5k needs chocolate during the run

    University College London Hospitals NHS Foundation Trust says snacks for shorter activities may only be needed to prevent or treat hypoglycaemia. Buying a bar does not mean you need to carry it as routine mid-run fuel.

    Consider the run’s duration, your meal timing and any established individual plan. Keep chocolate an optional, familiar snack if that is how you intend to use it.

  • Ethically sourced always means Fairtrade

    A broad sourcing statement does not identify which ingredients in a particular bar carry a Fairtrade claim. The Fairtrade Foundation also distinguishes its classic mark from its ingredient-specific mark.

    Check the exact wrapper or product information for the Fairtrade wording and which ingredients it names.

  • Dark or vegan-recipe chocolate has no allergy warning

    Warnings vary between products. Lindt Shop UK says its EXCELLENCE Dark 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy.

    Read the current pack’s ingredients and allergen statement for the precise bar and flavour you plan to eat.

Which brands are relevant to check?

These brand references concern the specified bars and claims, not every product a brand makes or what Joybuy stocks.

Divine

Divine Chocolate describes its plain 70% dark bar as made with Fairtrade ingredients.

  • Its product information lists 31.7g carbohydrate and 44.3g fat per 100g for that plain 70% bar.
  • Check the claim and allergen information for the exact variant; figures for the plain bar do not describe a raspberry bar.

Green & Black's

The specified 70% dark bar has product information identifying Fairtrade cocoa, sugar and vanilla.

  • The Joybuy product information discloses that those Fairtrade ingredients may be mixed with non-certified equivalents on a mass-balance basis.
  • Mass balance should not be read as a claim that certified ingredients are physically segregated in each bar; check the current pack for its exact mark.

M&S

Marks & Spencer describes its specified 75% bar as sourced from Fairtrade cocoa farms and its specified 85% bar as Fairtrade dark chocolate.

  • The two bars offer distinct stated cocoa percentages for shoppers comparing flavour preferences.
  • Read the current label for the chosen bar’s ingredients, nutrition and allergen information.

Montezuma's

Montezuma's FitzRoy is a 74% dark-chocolate bar; the brand describes its cocoa as certified.

  • The FitzRoy product information states its cocoa-solids percentage and gives may-contain warnings for milk, nuts and peanuts.
  • A statement about certified cocoa does not, on its own, identify a product-specific Fairtrade claim for FitzRoy.

Lindt

Lindt describes a responsible-sourcing programme for its cocoa products; its EXCELLENCE Dark 70% bar is a separate product-level choice to check.

  • Lindt Shop UK provides an explicit milk-allergy warning despite describing that bar as made to a vegan recipe.
  • The sourcing-programme statement does not establish that the specified 70% bar is Fairtrade-certified.

Hotel Chocolat

Hotel Chocolat describes its cacao as ethically sourced and offers dark-chocolate formats.

  • Shoppers can check individual dark-chocolate formats against their preferred ingredients and flavour.
  • The brand’s ethical-sourcing description is not a product-specific Fairtrade claim; check the particular bar if Fairtrade is required.

Questions about chocolate and a 5k

Do you need dark chocolate during a 5k?

Not as routine fuel for a shorter activity. University College London Hospitals NHS Foundation Trust says snacks for shorter activities may only be needed to prevent or treat hypoglycaemia. If you manage blood glucose or have an individual exercise plan, follow the advice specific to you.

Does 85% cocoa make a bar better fuel than 70%?

Cocoa percentage alone does not establish how suitable a bar is as a run snack. Compare the exact products’ carbohydrate and fat information, consider when you would eat the bar and choose a flavour you already know you tolerate. If you need a prompt carbohydrate top-up, do not assume dark chocolate serves the same purpose as a snack chosen for that need.

What do the different Fairtrade marks tell you?

According to the Fairtrade Foundation, the classic FAIRTRADE Mark indicates that all ingredients capable of Fairtrade certification are covered. A Fairtrade Sourced Ingredient mark identifies a particular ingredient, such as cocoa. Check which mark and ingredients appear on the exact chocolate bar.

Is vegan-recipe dark chocolate suitable for a milk allergy?

Do not rely on the recipe description alone. Lindt Shop UK says its EXCELLENCE Dark 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Read the current allergen statement for the exact bar you intend to eat.
