For a hike, choose the formula and caffeine amount per can before deciding how many cans to buy. Red Bull states that its 250ml original can contains 80mg caffeine; larger 500ml options call for a closer look at the exact variant’s label, particularly if you also have coffee, tea or caffeine gels. Carry water separately: the NHS says water is the best way to replace fluids lost through physical activity.
The useful distinction is not simply how many cans are in the pack, but what each can contains and whether its size works alongside your snacks and water.
A 250ml can takes up less carrying space than a 500ml can. If caffeine amount matters, Red Bull states that its 250ml original can contains 80mg; check the label of any different formula rather than carrying that figure across variants.
Check both sugars and caffeine on the exact multipack. Tesco lists a Monster Absolutely Zero Sugar 500ml can with 180mg caffeine, so zero sugar does not mean caffeine-free.
Count other sources, including coffee, tea and caffeine gels, alongside the drink. The NHS advises no more than 200mg caffeine a day during pregnancy; high-caffeine product warnings also need attention when pregnant, breastfeeding or sensitive to caffeine.
Start with your water supply, then compare the exact can’s caffeine and sugar information before choosing a pack format.
| Priority | What to check | Your needs |
|---|---|---|
| Water | Plan a separate water supply. The NHS says to drink extra fluids after sweating through physical activity and identifies water as the best way to replace lost fluids. | I want enough water for the walk without relying on a canned energy drink as my main drink. |
| Caffeine per can | Read the amount for the exact can and count other caffeine that day. Red Bull states 80mg per 250ml original can; Tesco lists 180mg per 500ml Monster Absolutely Zero Sugar can. These figures do not apply to every variant from either brand. | A smaller caffeine serving matters to me, or I will already have coffee, tea or a caffeine gel. |
| Sugar formula | Compare the exact nutrition labels. Tesco lists its Monster Absolutely Zero Sugar can with 0g sugars, while Lucozade says its Energy range contains glucose; check the chosen Lucozade pack rather than assuming all variants have identical values. | Do I want a glucose-containing drink with my snacks, or would I rather choose a zero-sugar formula? |
| Can and pack size | Check individual can volume, can count and the space available in your bag. Tesco lists 250ml Red Bull multipacks and 500ml Monster and Relentless multipacks, among other formats. | I may share a multipack at home, but only want to carry the number of cans that fits this hike. |
Sweating during a hike can increase the need for fluids. The NHS identifies water as the best way to replace fluids lost through physical activity.
Pack water independently, then decide whether you also want a canned drink with your snacks.
Can size changes both what you carry and the caffeine amount you might drink at once. Red Bull states 80mg per 250ml original can, while Tesco lists 180mg per 500ml Monster Absolutely Zero Sugar can.
Check caffeine per can on the exact variant; if the label gives only a per-100ml value, use the can volume to work out the full-can amount.
A zero-sugar Monster variant and the glucose-containing Lucozade Energy range answer different preferences. A shared product category does not tell you the nutrition values of a particular can.
Read the sugar and caffeine information on the multipack you intend to buy.
These examples help distinguish formats and formulas; a brand’s inclusion does not mean every variant has the same nutrition or caffeine values.
Tesco lists multipacks of 250ml Red Bull Energy Drink cans, a smaller individual-can format than the 500ml options discussed here.
Tesco lists a 4 × 500ml Monster Absolutely Zero Sugar multipack for shoppers comparing larger, zero-sugar cans.
Tesco lists Relentless Origin in a 4 × 500ml format.
Tesco lists Lucozade Energy Original in an 8 × 380ml multipack; Lucozade describes its Energy range as containing glucose.
Tesco Groceries lists multipacks from Red Bull, Monster, Relentless and Lucozade.
Relentless names Sainsbury's among its UK retailers.
These Joybuy options are Red Bull and Monster canned multipacks in 250ml and 500ml formats. Compare each exact formula and label; the larger cans and the zero-sugar variants are not interchangeable.

Eight smaller cans offer an individually portioned option to pack alongside hiking snacks. The product information states 80mg caffeine and 28g sugars per 250ml can. Count other caffeine consumed that day and carry water separately.

This eight-can, 250ml format combines a smaller can with a stated 0g sugars. Check caffeine per can on the exact label before choosing it for a hike: the product descriptions give conflicting caffeine information. Its product warning advises against use by children, pregnant or breastfeeding women, and people sensitive to caffeine.

This is a larger, sugar-containing can for someone deliberately choosing that format rather than a compact 250ml serving. The product information states 160mg caffeine per 500ml can and 11.4g sugars per 100ml; it also recommends no more than one can per day. Check the label and take water separately.

Four 500ml cans provide a zero-sugar option for shoppers who want the larger format; the product information states 0g sugars per can. Check caffeine per can on this variant’s label rather than applying the figure from a different Monster drink. Its high-caffeine warning advises against use by children, pregnant or breastfeeding women, and people sensitive to caffeine.
No. The NHS says water is the best way to replace fluids lost through physical activity. Carry water separately and decide whether you also want a canned drink with your snacks.
Compare caffeine per can as well as carrying size. Red Bull states 80mg for its 250ml original can, while Tesco lists 180mg for a 500ml Monster Absolutely Zero Sugar can. Read the exact variant’s label: neither figure applies to every drink of that size.
Check the product warning and account for caffeine from every source before choosing a drink. The NHS advises no more than 200mg caffeine a day during pregnancy, and several of the high-caffeine products discussed here warn against use during pregnancy or breastfeeding. Seek individual clinical advice if you are unsure what applies to you.
Check the best-before date and the storage instructions on the exact pack, then choose how many cans you want to carry on each walk. Pack size need not determine how many cans go in your hiking bag.
