For long runs, plan fluid and carbohydrate around the session rather than relying on glass-bottle lemonade as your only fuel. World Athletics advises fluid and carbohydrate during prolonged events; regular lemonade can contribute carbohydrate, but the amount varies by drink, while zero-sugar versions contribute little or none. A glass bottle may suit a drink after training, but check your event’s rules and choose a carrying method you have practised for the run itself.
If a run lasts more than an hour, you need to consider fluid, carbohydrate and what you can tolerate while moving—not just whether a drink tastes appealing. World Athletics advises replacing fluid and carbohydrate during prolonged events.
A glass bottle may appeal for serving a drink after training. For the run itself, consider how you will carry fluids and check the particular event’s guidance rather than choosing by packaging alone.
If you want lemon flavour without much carbohydrate, distinguish that preference from fuelling a long session. A separate carbohydrate source may be needed as part of your running plan.
Start with the run’s duration and your fluid-and-fuel plan, then compare the exact drink label and the container you would use.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate | Compare grams per 100 ml with the volume you expect to drink and any separate fuel. World Athletics gives 30–60 g per hour for events lasting 1–2.5 hours, and up to 90 g per hour beyond 2.5 hours. | For a long run, I want to know how the drink fits into my hourly fuel plan, rather than assuming that a sweet taste supplies enough carbohydrate. |
| Fluid and electrolytes | Check the stated salt or sodium amount on the same quantity basis when comparing labels. Consider the drink alongside your fluid plan, particularly when conditions or sweat losses change. | I need a way to carry and drink fluid that I can practise in training; a lemon-flavoured drink alone does not establish its electrolyte contribution. |
| Format and tolerance | Check whether the exact drink is carbonated, its pack size and material, and the event’s container guidance. London Marathon Events identifies hydration vests and hand-held running bottles for runners carrying their own container. | A glass bottle appeals for serving, but I would choose an on-run container around my carrying method and the rules of my particular event. |
| Sugar and acidity | Read carbohydrate and sugars for the exact regular or diet variant. Torbay and South Devon NHS Foundation Trust identifies acidic drinks, including sugar-free lemonade, as a potential cause of dental erosion. | If I only want a lemon-flavoured drink after training, I do not need to treat it as fuel. Sugar-free also does not mean acid-free. |
Drink labels give carbohydrate per 100 ml, while endurance guidance expresses intake per hour. R. White’s regular lemonade lists 2.4 g carbohydrate per 100 ml; supplying 30 g from that drink alone would take 1,250 ml, without accounting for fluid tolerance or other fuel.
Use your run duration and a practised plan to compare the drink’s stated carbohydrate with what you expect to consume overall.
Sprite Zero lists 0 g carbohydrate per 100 ml, according to Coca-Cola Great Britain; M&S Diet Lemonade lists 0.1 g per 100 g, according to Marks & Spencer. Neither is a meaningful carbohydrate source for a long run.
Choose a separate, planned carbohydrate source if the session calls for one.
A bottle suited to serving at home may be awkward to carry while running. London Marathon Events describes hydration vests and hand-held running bottles as carry-your-own options; arrangements differ between events.
Check your race’s current participant guidance and practise with the container you intend to use.
Torbay and South Devon NHS Foundation Trust identifies acidic drinks, including lemonade advertised as sugar-free, as a potential cause of dental erosion.
Bear the frequency of drinking lemonade in mind, rather than sipping it throughout the day simply because it contains no sugar.
Compare the exact variant and pack: a familiar lemonade name does not establish its carbohydrate content or whether its bottle is glass.
Regular and diet lemonades serve different purposes when carbohydrate matters.
A carbonated lemon-and-lime alternative available in regular and zero-sugar forms.
Its Freshly Squeezed Lemonade is a sparkling drink offered in 275 ml and 750 ml sizes.
Its lemonade range includes standard, diet and premium sparkling options.
Its Diet Lemonade is an option when the aim is lemonade flavour rather than carbohydrate fuel.
These options include sports and electrolyte drinks plus a carbonated lemon drink. Compare their stated carbohydrate and salt or sodium with your running plan; none should be assumed to be glass-bottle lemonade.

An isotonic sports-drink option to compare with lemonade when planning carbohydrate and fluid for training. The listing states 6.3 g carbohydrate and 0.12 g salt per 100 ml; work the amount you intend to drink into your wider plan.
The listing says it contains aspartame, a source of phenylalanine, and is not suitable for people with phenylketonuria. Check carbonation and bottle material if either affects your choice.

This isotonic drink lists 6.2 g carbohydrate and 49 mg sodium per 100 ml, figures you can use when comparing it with your planned fuel and fluid intake.
Consider whether a 900 ml bottle fits your carrying method. Check its carbonation and container material before choosing it for a run or a glass-bottle preference.
No image available
A carbonated isotonic drink in a can, not a glass-bottle lemonade. Its listing states 4.9 g carbohydrate and 0.11 g salt per 100 ml.
If considering it during a run, practise with carbonation first and assess its contribution alongside the rest of your fuel and fluid plan.

For a lemon-flavoured option with stated nutrition, this drink lists 6.3 g carbohydrate and 0.10 g salt per 100 ml. It is described as an electrolyte drink, not as lemonade.
Check carbonation and container material if you intend to carry it while running or want a particular type of bottle.

This carbonated lemon drink lists 7.9 g carbohydrate per 100 ml. It may be considered as a secondary carbohydrate drink if you have practised using it, not as your entire marathon fuel-and-fluid plan.
It comes in cans rather than glass bottles. Consider whether carbonation suits you while running.
Do not assume lemonade alone covers your fluid and fuel plan. World Athletics advises replacing fluid and carbohydrate during prolonged events; regular lemonades differ in their stated carbohydrate and salt, so compare the exact label with what you intend to drink and any separate fuel you have practised using.
It provides little or no carbohydrate fuel. Coca-Cola Great Britain lists 0 g carbohydrate per 100 ml for Sprite Zero, while Marks & Spencer lists 0.1 g per 100 g for M&S Diet Lemonade. Plan a separate carbohydrate source when your session calls for one.
Check the rules for your particular event before bringing one. London Marathon Events identifies hydration vests and hand-held running bottles for runners carrying their own containers; that guidance does not establish a rule for every marathon.
No. Torbay and South Devon NHS Foundation Trust identifies acidic drinks, including lemonade advertised as sugar-free, as a potential cause of dental erosion. Consider how often you drink it, rather than treating the sugar-free label as a statement about acidity.
It can be a choice for flavour and serving after a run, but the bottle does not establish its suitability as running fuel. Check the exact drink’s label if its carbohydrate content matters to your wider food-and-fluid plan.
