For a short ride, choose plain still water if you want hydration without a flavoured drink’s ingredients; choose sugar-free flavoured water if you prefer its taste and its current label suits you. Bottle size matters too: pick one you can carry or use to refill your cycling bottle. For rides over 90 minutes, water alone does not provide the 30–60g of carbohydrate per hour advised by British Cycling.
If you ride for around an hour or less, or want water around your rides, plain water avoids the ingredients of a flavoured drink. Sugar-free flavoured water offers a different taste, but check its label if particular ingredients matter to you.
Water can be part of your drink plan, but it is not carbohydrate fuel. British Cycling advises 30–60g of carbohydrate per hour for rides over 90 minutes, so plan what you will eat or drink alongside water.
If flavour makes water more appealing, compare the sugar declaration and ingredients on the exact bottle. A sugar-free label does not mean the drink has the same ingredients as plain water.
Start with the length of your ride, then check the drink’s label and whether its bottle fits where you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Ride duration | Decide whether you need water alone or a separate fuelling plan. British Cycling says most indoor sessions under an hour do not need additional fuel during the session; for rides over 90 minutes, it advises 30–60g of carbohydrate per hour. | I want water for a short session, but I need to plan carbohydrate separately when my ride lasts over 90 minutes. |
| Sugar and ingredients | Read the sugars per 100ml declaration and the ingredients on the exact bottle. A sugar-free flavoured drink may contain sweeteners and other ingredients: Tesco Groceries lists sucralose, citric acid and potassium sorbate in Highland Spring Lemon & Lime. | If I choose flavoured water, I want to know what gives it its flavour and whether its current sugar declaration suits me. |
| Bottle format | Check individual bottle capacity, pack size and how you will carry or refill it. UK retailer listings include 500ml bottles and larger formats; Tesco Groceries also lists a 1L Buxton sports-cap bottle. | A smaller bottle may fit what I carry on a ride; for home use, I might prefer larger bottles to refill my cycling bottle. |
| After opening | Follow the storage instructions on the specific bottle. Tesco Groceries lists Highland Spring Lemon & Lime with instructions to chill after opening and use within 3 days. | If I will open a larger flavoured bottle over several days, I want its storage instructions to fit how I will use it. |
Plain water and sugar-free flavoured water are drink choices, not substitutes for the carbohydrate British Cycling advises for rides over 90 minutes.
Plan carbohydrate separately for a longer ride rather than relying on the word “hydration” on a bottle.
A flavoured drink can contain other ingredients even when its sugars declaration is 0g per 100ml. Tesco Groceries lists sweetener, acid and preservative in Highland Spring Lemon & Lime.
Check both the nutrition panel and ingredients list on the product you intend to buy.
A larger bottle may suit use at home or in a vehicle but be awkward to take on the bike; smaller individual bottles change how many you need to carry.
Choose the capacity around your carrying space and refill opportunities, not pack size alone.
Storage instructions matter if you plan to drink from an opened flavoured bottle over several days.
Check the on-pack ingredients, nutrition declaration and after-opening instructions before making it a regular purchase.
These examples show product types and formats to compare; a brand name alone does not establish a drink’s nutrition or suitability for a particular ride.
Sainsbury’s lists Highland Spring among its still-water range. Tesco Groceries also lists a Lemon & Lime sugar-free flavoured water.

The six 1.5L bottles are a format to consider for water at home or for refilling a cycling bottle before you leave. Check the current pack if you need a precise nutrition declaration; choose a smaller bottle if you need to carry water during the ride.
For most indoor sessions under an hour, British Cycling says to keep hydrated but says additional fuel during the session should not be needed. For rides over 90 minutes, it advises 30–60g of carbohydrate per hour, which plain water does not provide.
Yes, if the current nutrition panel and ingredients suit what you are looking for. Tesco Groceries lists Highland Spring Lemon & Lime with 0g sugars per 100ml, but it also lists sucralose, citric acid and potassium sorbate, so check the exact product rather than assuming all flavoured waters are alike.
No. A mineral-water label identifies the product type, but it does not by itself establish what to drink for your session. Check the exact bottle’s declared composition and plan fluids around the ride’s conditions rather than relying on the product name alone.
Follow the instructions on your bottle. Tesco Groceries lists Highland Spring Lemon & Lime with directions to keep it chilled after opening and use it within 3 days; check the label of any other product separately.
