Maurten Gel 100 CAF 100 is a sports food gel that combines carbohydrates with 100 mg of caffeine.
Take one gel during exercise, typically when you need both an energy top-up and a caffeine boost - many athletes use it in the latter stages of a long session or race. No water is required to consume it, though staying hydrated alongside any carbohydrate gel is sensible practice. Check the packaging for specific guidance on timing and frequency relative to other caffeinated products you may be using.
Maurten Gel 100 CAF 100 is a sports food gel that combines carbohydrates with 100 mg of caffeine. It is designed to fuel endurance exercise, delivering fast-available carbohydrate energy alongside caffeine at a dose commonly associated with improved focus and reduced perceived effort during prolonged effort.
Maurten's gels are built around a hydrogel technology - a carbohydrate matrix that encapsulates the fuel and is intended to ease digestion during high-intensity work, when gut stress is a genuine concern for many athletes. The CAF 100 variant is the caffeinated version of the standard Gel 100, making it particularly suited to situations where mental sharpness matters as much as physical output: late-race fatigue, early-morning training starts, or multi-stage events.
It fits neatly into the toolkit of runners, cyclists, triathletes, and endurance athletes who want a reliable source of carbohydrate energy without the need to manage a separate caffeine strategy. The texture is relatively thin compared with traditional gels, and it requires no water to wash down - though drinking alongside it is always sensible.
Maurten has become a reference brand in elite endurance sport, used visibly at major marathon and cycling events worldwide. The formulation is deliberately minimal: no artificial colours, no strong flavours, no unnecessary additives. What you get is carbohydrate and caffeine in a format the gut tends to tolerate well, even under race conditions.

Sign inMost endurance athletes take caffeinated gels in the second half of a long effort — when fatigue is building and mental focus starts to slip. The exact timing will depend on your overall nutrition and caffeine strategy for the session or race.
The CAF 100 contains 100 mg of caffeine; the standard Gel 100 does not. The carbohydrate content and hydrogel format are otherwise the same. If you are caffeine-sensitive or training late in the day, the non-caffeinated version may be the better choice.
Caffeine accumulates, so it is worth accounting for all sources — coffee, gels, chews, or drinks — across a session. Most guidance suggests capping total caffeine intake at around 3–6 mg per kg of body weight for performance use, but check with a sports dietitian if you are unsure what is appropriate for you.
It works for either, but the caffeine content makes it most useful for higher-intensity or longer sessions where you genuinely need the stimulus. For routine easy training, a non-caffeinated gel or whole-food carbohydrate source may be more appropriate.
No — the hydrogel format is designed to be consumed without water, which is one of its practical advantages in race settings. That said, maintaining general hydration during exercise remains important regardless of the gel format.
Overall

Started using this at mile 16 of long Sunday runs and honestly the difference in how sharp I feel heading into the last stretch is noticeable. The caffeine doesn't hit like a jolt — more of a steady lift. Easy on the stomach too, which has been my biggest problem with other gels.

I've had real issues with GI distress mid-race. Tried these for the first time at a half marathon and had zero issues. The texture is thinner than I expected but I actually prefer it. Will be stocking up before my spring marathon.

Genuinely one of the best gels I've used — no stomach issues, the caffeine keeps me focused during long rides. But at £38.50 for a box it's tough to justify using these on every training session. I tend to save them for race day or key sessions now.

Used these during my first full Ironman. Took one at the start of the run leg and felt noticeably more alert. Nothing fancy going on — just does the job.

I've now used these across three marathons and the experience is always the same — predictable energy, no surprises in the gut. That reliability is worth a lot when you're racing. The caffeine version is what I reach for from the halfway point onwards.

I do a lot of 5am training runs before work and really don't have time to eat properly beforehand. These have become part of my routine — one before I leave and I'm good to go. The caffeine keeps me functional for the first hour.
