A milkshake can be a convenient carbohydrate-and-protein snack after an intense or prolonged training run, but it should not replace a practised marathon race-fuelling plan. Compare what the portion you will drink provides, check whether its storage and milk ingredients suit you, and plan carbohydrate and fluid intake for long runs separately.
A milkshake is most relevant as a post-run food option; whether it suits you also depends on where you will drink it and how you plan to fuel longer runs.
If you want something convenient soon after an intense or prolonged run, compare the carbohydrate and protein in the bottle or serving you would actually drink. The UK Sports Institute advises a carbohydrate-and-protein-rich snack and fluids after this kind of exercise.
A larger bottle lets you pour a serving rather than drink an entire single-serve pack. Check its serving information, refrigeration instructions and how soon it must be used after opening.
Keep a recovery snack distinct from your long-run fuelling plan. World Athletics distance-running research describes a personalised, practised approach to carbohydrate and fluids that takes practical opportunities and gut comfort into account.
Start with when you intend to drink the milkshake, then compare nutrition for the portion, ingredients and storage directions on the current pack.
| Priority | What to check | Your needs |
|---|---|---|
| Post-run portion | Read carbohydrate and protein per 100ml and for the bottle or serving you will have. Check whether you also need food and fluids afterwards. | I want a convenient snack after a hard or long run, without assuming one drink covers everything I will eat and drink afterwards. |
| Long-run fuelling | Plan carbohydrate and fluids around the run; practise the foods and drinks you intend to use. Consider practical access and gut comfort. | For long runs or race day, I need a plan I have tried in training rather than relying on an unfamiliar milkshake. World Athletics distance-running research supports a personalised, practised approach. |
| Comparable labels | Compare carbohydrate, sugars, protein and energy on the same per-100ml basis, then check the stated serving or whole container. Pack sizes can differ. | I want to know what my usual portion contains, not judge two different-sized drinks by their front labels alone. |
| Milk ingredients | Read the current ingredients and emphasised allergen declaration for the exact product. Do not rely on an older listing if its formulation has changed. | If milk is an allergen for me, I need to choose a suitable alternative rather than treat flavour or branding as evidence of suitability. |
| Storage | Check whether the unopened drink needs chilling, what to do after opening and whether it has a use-by date. | When I buy a multi-serving bottle, I need to be able to refrigerate it and finish it within the pack’s stated period after opening. |
A drink that works after a run does not establish what carbohydrate and fluids will suit you during a marathon. World Athletics distance-running research also identifies gut discomfort as a consideration in planning race intake.
Use training runs to practise a separate food-and-fluid strategy before relying on it on race day.
Yazoo Strawberry and Müller FRijj Chocolate have different carbohydrate and protein values per 100ml on their respective product labels. Different container sizes change how much you consume.
Compare labels per 100ml, then read or work out the values for the amount you intend to drink.
A dairy milkshake is unsuitable if milk is an allergen for you. Ingredients may also differ between products from the same brand.
Check the current pack’s ingredients and allergen declaration for the exact drink; choose a suitable non-dairy alternative if necessary.
After-opening instructions vary. Sainsbury’s says to refrigerate its Chocolate Milkshake 1L and consume it within five days of opening, without exceeding the use-by date.
Follow the exact pack’s refrigeration, opened-container and date instructions. The Food Standards Agency distinguishes safety-related use-by dates from quality-related best-before dates.
These labelled examples illustrate different drink and pack formats; a brand name alone does not establish the nutrition or storage instructions of every product it sells.
A flavoured milk drink to compare with thicker milkshakes on the same serving basis.
A single-bottle milkshake format for someone considering a drink after a run.
A chilled, larger-bottle example for portioning a post-run drink at home.
A retailer with own-label and branded ready-to-drink formats to compare.
These are packs of ready-to-drink shakes for considering as post-run snacks. Compare their current nutrition labels for the portion you would have; they are not substitutes for a practised marathon fuelling plan.

A canned option for a post-run drink when you prefer a 250ml portion. The pack contains eight cans. Read the current nutrition and ingredient labels for the can you will drink, including its milk allergen declaration, and follow its storage instructions.
Do not assume a milkshake replaces a practised race-fuelling plan. World Athletics distance-running research describes planning carbohydrate and fluid intake around the event, practical opportunities and gut comfort; practise your intended approach during training.
After an intense or prolonged run, a milkshake can be one way to have a carbohydrate-and-protein snack. The UK Sports Institute also advises fluids after this kind of exercise; consider the drink alongside the rest of your food and drink rather than treating it as a complete plan.
Compare carbohydrate, protein, sugars and energy per 100ml, then check the values for the bottle or serving you expect to drink. Pack size, ingredients and storage directions matter too, so use each product’s current label.
Check the exact product’s current ingredients and allergen declaration, and avoid a milk-containing shake if milk is an allergen for you. GOV.UK explains that food businesses must identify specified allergens when they are ingredients in their food or drink.
Follow the instructions on the exact pack. Sainsbury’s Chocolate Milkshake 1L says to keep it refrigerated and consume it within five days of opening without exceeding the use-by date; another drink may have different directions. The Food Standards Agency distinguishes use-by dates, which concern safety, from best-before dates, which concern quality.
