Choose 100% apple juice if you want a measured contribution of carbohydrate to a marathon-training fuel plan, not a complete plan in one drink. The reviewed UK juice labels list 14.1g to 17g carbohydrate per 150ml serving; World Athletics advises 30–60g per hour for endurance events lasting 1–2.5 hours and up to 90g per hour for longer events. A no-added-sugar label does not tell you how much carbohydrate a drink contains, while a sugar-free apple soft drink should not replace planned fuel.
If a run lasts more than an hour, the distinction between a drink that supplies carbohydrate and one that mainly supplies flavour matters. World Athletics advises 30–60g carbohydrate per hour for endurance events lasting 1–2.5 hours and up to 90g per hour for longer events. A serving of juice can be counted within a plan, but not treated as the whole plan.
An apple flavour or a no-added-sugar claim does not establish a drink’s fuel contribution. ASDA Groceries lists 1.2g carbohydrate per 100ml for its Apple & Pear Juice Drink; its listing for Tango Zero’d Apple describes negligible carbohydrate. Check the exact drink’s carbohydrate figure if fuel is the aim.
A drink chosen for a long-run fuel plan is a different decision from an everyday glass of juice. NHS guidance advises limiting fruit juice and smoothies to 150ml a day in ordinary intake, drinking extra fluid after sweating and using water as the main way to replace lost fluid.
Start with the carbohydrate on the exact pack and the volume you intend to drink. Then consider how that drink fits your fluid routine and what you have practised during training.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate amount | Read carbohydrate per 100ml and per serving, then count the volume you plan to drink. The reviewed 100% juice labels give 14.1g to 17g per 150ml; World Athletics advises 30–60g per hour for 1–2.5-hour endurance events. | I want to know what the drink contributes to my long-run fuel plan, rather than assuming one glass covers an hour. |
| Drink type | Distinguish 100% juice, a juice drink and a sugar-free soft drink. ASDA Groceries lists 1.2g carbohydrate per 100ml for its Apple & Pear Juice Drink and negligible carbohydrate for Tango Zero’d Apple. | If I choose an apple-flavoured drink without much carbohydrate, I will need to obtain my planned fuel elsewhere. A no-added-sugar claim alone will not settle the question. |
| Fluid and tolerance | Check the serving volume and any carbonation or sweeteners. Practise the exact drink and any accompanying food or fuel during training; UK Sports Institute guidance notes that pre-run choices vary between individuals. | I need a drink and serving size I have tried on long runs, while keeping fluid and carbohydrate decisions deliberate. |
| Everyday portions | Separate deliberate endurance fuelling from routine drinking. NHS guidance advises limiting fruit juice and smoothies to 150ml a day in ordinary intake and identifies water as the main way to replace lost fluid. | Outside a planned training session, I want to treat juice as a measured drink rather than my default way to rehydrate. |
The phrase does not specify carbohydrate content. ASDA Groceries lists just 1.8g carbohydrate per 150ml carton for its Apple & Pear Juice Drink, while its Tango Zero’d Apple listing describes negligible carbohydrate.
Compare carbohydrate per serving with the amount you intend to take during the run. If the drink contributes little, plan fuel separately.
The reviewed 100% apple juice labels give 14.1g to 17g carbohydrate per 150ml. World Athletics advises 30–60g per hour for 1–2.5-hour endurance events and up to 90g per hour for longer events.
Count the carbohydrate in the volume you will actually drink, alongside any other food or sports products you have practised using.
NHS guidance to limit fruit juice and smoothies to 150ml a day addresses ordinary intake; prolonged endurance exercise also calls for deliberate fuel and fluid planning. Neither context makes juice an unrestricted everyday hydration drink.
Keep routine drinks and a measured long-run fuel plan distinct. Use water as the main way to replace lost fluid in ordinary circumstances, in line with NHS guidance.
A new drink, serving volume or combination with other fuel may not suit the routine you have practised. UK Sports Institute guidance notes that pre-run choices vary between individuals.
Try the exact product, volume, timing and any accompanying fuel on training runs before relying on that combination for an event.
These product-line examples show why the nutrition panel and drink description matter more than an apple-flavour label alone.
Tesco Groceries lists Tropicana Pressed Apple Juice as 100% pressed juice with no added sugar and naturally occurring sugars.
ASDA Groceries lists both a 100% pressed Apple Juice and a separate Apple & Pear Juice Drink; they are different drink types.
Sainsbury's lists a 100% pressed apple juice made from apple juice and not from concentrate.
Marks & Spencer publishes a UK nutrition panel for its Apple Juice.
Sainsbury's lists Copella Cloudy Apple Fruit Juice in 300ml, 900ml and 1.35L formats.
These options cover an apple-flavoured sugar-free soft drink, apple juice, fruit water and an apple juice drink. Choose by the drink type and the nutrition panel on the exact pack; the formats are not interchangeable as training fuel.

An apple-flavoured sugar-free option when carbohydrate fuel is planned separately.
The pack contains eight 330ml cans. Check the carbohydrate figure on the can rather than counting this drink towards a long-run fuel target.

A bottled apple juice to consider if you want to measure a serving as part of a training fuel plan.
The bottle is 1L. Check its carbohydrate per serving and drink classification on the pack before calculating its contribution.

A sparkling 100% apple juice option if you want a defined can size for counting what you drink.
The pack contains six 250ml cans. Practise with a sparkling drink during training before making it part of an event-day plan.

An apple-and-pear fruit water in small cartons for someone choosing a drink by portion size.
The pack contains three 200ml cartons. Fruit water is not the same product type as 100% apple juice; use its own carbohydrate panel when planning fuel.

An individual apple juice drink carton to compare with juice and sugar-free soft drinks.
The carton is 248ml. Because it is described as a juice drink rather than 100% apple juice, check its own carbohydrate per serving before including it in a fuel plan.
Yes, as one measured source of carbohydrate rather than a complete plan. The reviewed 100% juice labels give 14.1g to 17g per 150ml serving; World Athletics advises 30–60g per hour for 1–2.5-hour endurance events and up to 90g per hour for longer events. Count the amount you will actually drink alongside other fuel you have practised using.
No: the phrase does not tell you whether the drink supplies enough carbohydrate. ASDA Groceries lists 1.2g carbohydrate per 100ml, or 1.8g per carton, for its Apple & Pear Juice Drink. Read the carbohydrate figure on the exact product rather than relying on the front-of-pack wording.
No. ASDA Groceries describes the reviewed Tango Zero’d Apple as a carbonated sugar-free apple soft drink with negligible carbohydrate. It can be a flavour choice, but it should not stand in for carbohydrate planned for a marathon.
Use water as the main way to replace lost fluid, in line with NHS guidance, which also advises drinking extra fluid after sweating. For ordinary intake, the NHS advises limiting fruit juice and smoothies to 150ml a day; keep any deliberate endurance-fuelling plan distinct from everyday drinking.
Try the exact drink and serving size during training first. UK Sports Institute guidance notes that pre-run food and drink choices vary between individuals, so practise the timing and any accompanying fuel on long runs before relying on that combination for an event.
