Drink Mix 320 Caf 100 is a carbohydrate-based sports drink mix from Maurten, formulated with caffeine.
Mix one serving with water as directed on the packaging and consume during exercise. It is designed for use mid-effort - not before or after - and is best suited to sessions or races lasting long enough to require mid-exercise fuelling. Follow the preparation instructions on the pack for the correct water volume.
Drink Mix 320 Caf 100 is a carbohydrate-based sports drink mix from Maurten, formulated with caffeine. Maurten's drink mixes are built around a hydrogel technology that encapsulates carbohydrates in a gel-like matrix within the gut, which is studied for its role in reducing gastrointestinal discomfort at the high carbohydrate intakes that endurance athletes require. The "320" in the name refers to the carbohydrate content per serving, making this a high-density fuel source designed for sustained, demanding output. The "Caf 100" indicates 100mg of caffeine per serving - a dose in line with what sports science commonly associates with improved focus, reduced perceived effort, and maintained performance in the later stages of a race or long training session.
This mix suits endurance athletes - runners, cyclists, triathletes - who need reliable, gut-friendly fuel alongside a caffeine boost timed to performance. It works particularly well in longer efforts where both energy availability and mental sharpness become limiting factors. The product is designed to be mixed with water and consumed during exercise rather than as an everyday drink.
Maurten has built a strong reputation among elite endurance athletes and their coaches precisely because the formulation prioritises gut tolerability at high carbohydrate loads - a practical concern that many standard sports drinks overlook. If your training or racing runs long, that distinction matters.

Sign inDrink Mix 320 Caf 100 is designed for consumption during exercise, not before or after. For longer sessions or races, start fuelling early and sip consistently rather than waiting until you feel depleted. Check the packaging for specific preparation guidance.
Maurten's hydrogel approach encapsulates carbohydrates in a gel-like matrix that forms in the gut. This is studied for its potential to improve tolerance of high carbohydrate intake during exercise — a common limiting factor for endurance athletes who experience stomach discomfort with standard sports drinks.
100mg is a moderate caffeine dose — roughly equivalent to a strong cup of coffee. It falls within the range commonly studied for performance benefits. If you are sensitive to caffeine, unused to it in training, or are taking this late in the day, that is worth weighing up before use.
This product is formulated as a high-carbohydrate fuel source, which makes it most relevant for longer, higher-intensity efforts where carbohydrate availability and focus genuinely become limiting factors. For shorter sessions, the carbohydrate and caffeine load may be more than you need.
Yes. As with any caffeinated food or drink, consuming this product close to sleep is likely to interfere with sleep quality. Time its use to your training schedule and avoid late-evening sessions where sleep may be compromised.
Overall

Been using this for the past few months on anything over 3 hours. The caffeine hit towards the end of a long ride is noticeable — not jittery, just present. Gut feels fine even when I'm pushing hard, which wasn't the case with a couple of other brands I tried. Worth every penny for the reliability.

Does exactly what it promises — stomach stayed calm even in the heat and I felt the caffeine working when I needed it most. Only thing stopping me going full 5 stars is the price. At £37.99 a box it adds up fast if you're training 5 days a week. I ration it for key sessions and races now.

Started using this during my marathon build-up after a club mate swapped to it and wouldn't stop talking about it. Mixed it the night before a long run a couple of times to test my gut — zero issues. Took it on race day from mile 18 and felt noticeably sharper through to the finish. Genuinely impressed.

I've had GI issues in every triathlon I've ever done. A coach recommended I try this and honestly the difference has been significant. I can actually absorb what I'm taking in rather than spending half the run leg regretting my nutrition choices. The caffeine is a bonus.

Third cycle sportive this year that I've used this on. Mixes cleanly, no residue in the bottle, and I feel fuelled through to the end. The focus boost around hour 4 is real — I notice when I forget to take the caf version vs the standard one.

The sachets are tricky to open mid-ride with sweaty hands — I've wasted a fair bit trying to tear them open while moving. The product itself is excellent though. Fuelled a 5-hour sportive last month with no stomach trouble and good energy all the way. Just pre-mix before you leave if you can.
