Plain still water is an option when you mainly need fluid for a shorter ride, but a can’s closure matters if you plan to drink in stages: a resealable 500ml can is more practical for that than a 330ml ring-pull can. A 1999 exercise review indexed by PubMed says water alone is sufficient for fluid replacement during exercise under 90 minutes, while carbohydrate-electrolyte drinks should be considered for exercise lasting longer than 90 minutes. Canned water can remain part of a longer-ride plan, but the can itself is not a fuelling strategy.
For an indoor session or a ride under 90 minutes, you may want plain water ready before, during or afterwards. A resealable can is worth considering if you will drink at several stops rather than finish it in one sitting. The under-90-minute distinction comes from a 1999 exercise review indexed by PubMed.
For exercise lasting over 90 minutes, consider fluids and fuelling together rather than treating plain canned water as a sports drink. The 1999 review indexed by PubMed advises considering a carbohydrate-electrolyte drink for prolonged exercise; the water can still be one part of what you take.
Individual cans can be stocked at home or offered at a club or event base. Decide whether people will finish each portion at once, then check the can size, closure and total pack volume before choosing a case.
Start with the ride and how you will drink, then compare the water type and the amount in each pack.
| Priority | What to check | Your needs |
|---|---|---|
| Ride duration | Decide whether you need fluid alone or a separate fuelling plan. A 1999 exercise review indexed by PubMed distinguishes exercise under 90 minutes from prolonged exercise over 90 minutes, for which it advises considering a carbohydrate-electrolyte drink. | For a shorter ride, I want water for fluid replacement. On a longer ride, I need to plan fuel as well as what I will drink. |
| Closure and portion | Check whether the lid is stated to be resealable or is a ring-pull. Compare the individual can sizes: the Cano Water packs listed here are 500ml resealable cans and 330ml ring-pull cans. | I expect to drink at several stops, so being able to close the container matters. For a drink I will finish at an event base, a smaller ring-pull portion may work. |
| Water type | Read the exact product description for still or sparkling water. Check the ingredients and nutrition panel rather than assuming that mineral water supplies carbohydrate or the sodium planned for a longer ride. | Still water is what I want to take on this ride; I would check a sparkling can before substituting it. |
| Pack quantity | Compare both can count and volume per can, then consider how many portions you will use or store. Tesco Groceries also lists still-water bottle multipacks if a bottle format better suits your routine. | For home or club stock, I care about the total amount of water and whether each portion is likely to be finished once opened. |
Plain canned water provides fluid, not a carbohydrate-electrolyte formulation. A 1999 exercise review indexed by PubMed advises considering carbohydrate-electrolyte drinks when exercise lasts longer than 90 minutes.
Plan what you will drink and how you will fuel a longer ride separately; do not rely on mineral-water branding to answer both questions.
Once opened, a ring-pull can cannot be closed in the way a stated resealable can can. That difference matters if you intend to keep the same drink between stops.
Check for a resealable closure, or put the water in a clean cycling bottle before setting out.
A case of 12 × 500ml cans and one of 24 × 330ml cans contain different amounts of water and serve different portion needs. Can count also tells you nothing about the closure.
Check the number of cans, volume per can and lid type together, then choose the combination you can use and store.
These brand examples illustrate different water formats; a brand name alone does not identify the closure, carbonation or pack you will receive.
Its listed still-water cases include 12 × 500ml resealable cans and 24 × 330ml ring-pull cans.
Evian’s UK product information includes a 33cl sparkling-water can.
Tesco Groceries lists a 12 × 500ml still-water bottle multipack from Highland Spring.
Volvic’s UK product information provides mineral composition for its 1L bottled natural mineral water.
Tesco Groceries lists an 8 × 500ml still-water bottle multipack from Buxton.
Tesco Groceries lists its own British Natural Mineral Water still multipack in 12 × 500ml bottles.
These canned-water options are relevant to shorter rides, drinking before or after cycling, or keeping individual portions at home or an event base. Check the water type, closure and delivered pack quantity for the option you choose.

For plain water that you expect to drink in stages, this pack has 12 still-water cans of 500ml each with a stated resealable closure. Plan longer-ride fuelling separately rather than treating the water as a sports drink.

For individual drinks at home or an event base, this case contains 24 still-water cans of 330ml each with ring-pull closures. Its product information lists 0g carbohydrate, 0g sugars and 0g salt per 100ml; plan longer-ride fuelling separately.

For individual water portions, check whether the 330ml can suits where you intend to drink it. Confirm whether the water is still or sparkling, how the can opens and the delivered pack quantity before choosing it for a ride or event.
For fluid replacement during exercise under 90 minutes, a 1999 exercise review indexed by PubMed says water alone is sufficient. For exercise lasting over 90 minutes, it advises considering a carbohydrate-electrolyte drink; plan fluids and fuel together rather than assuming plain water covers both.
Choose a stated resealable closure if you expect to drink from the same can in stages. The Cano Water 12 × 500ml case is labelled resealable, while its 24 × 330ml ring-pull case is a more straightforward choice for portions you expect to finish in one sitting.
Do not assume it does. Mineral values depend on the exact water: Volvic lists 12mg sodium per litre for its 1L natural mineral water, while Highland Spring states 5.6mg per litre for its water. Neither figure establishes that the water supplies the carbohydrate considered for prolonged exercise in the 1999 review indexed by PubMed.
You can choose the water type you prefer, but check the exact can before substituting it. Evian identifies its 33cl can as sparkling, whereas the Cano Water cases shown here are labelled still; carbonation and closure are separate things to check.
Check whether the water is still or sparkling, the ingredients and nutrition panel, volume per can, closure and total pack quantity. For natural mineral water in England, Department for Environment, Food & Rural Affairs guidance says its composition must be stated on the label, so compare the exact product rather than relying on the brand name.
