The Maurten Gelflask is a reusable flask designed to carry Maurten's hydrogel-based energy gels during training and racing.
Fill the flask with your chosen Maurten energy gel before your session or race. Consume as you would a standard gel sachet - sip directly from the nozzle during exercise, following your planned carbohydrate intake schedule. Rinse thoroughly after each use.
The Maurten Gelflask is a reusable flask designed to carry Maurten's hydrogel-based energy gels during training and racing. Rather than tearing open individual sachets mid-effort, athletes can pre-fill the flask and consume their fuel in controlled amounts without breaking stride. This suits runners, cyclists, and triathletes who prefer to consolidate their nutrition carry - particularly useful in longer events where multiple gel sachets would otherwise mean more pocket bulk and more waste.
The flask is purpose-built for Maurten gels, whose hydrogel matrix has a thicker, more viscous consistency than most conventional gels. The nozzle and capacity are designed with that texture in mind, making it easier to dispense the gel smoothly under race conditions. It is reusable, which reduces single-use packaging across a heavy training block.
This is an accessory rather than a supplement in itself - it contains no active ingredients and delivers no nutritional value independently. Its clinical relevance sits squarely in execution: even a well-designed fuelling strategy fails if the practical delivery is awkward. For athletes following a carbohydrate periodisation protocol or race-day nutrition plan, having reliable, familiar equipment removes one variable from the equation. Pair it with the appropriate Maurten gel for your target carbohydrate intake per hour, as guided by your nutrition plan or coach.

Your first order creates it. Add your blood results or a wearable, and a doctor can recommend what suits you.
Sign inIt is designed specifically for Maurten's energy gels, which have a thicker hydrogel consistency. It may work with other gels, but the nozzle and sizing are optimised for Maurten's formulations.
Check the product packaging for the exact capacity. As a rule, it is intended to hold enough gel for one or more standard servings — refer to the label or Maurten's guidance for precise fill volume.
Rinse with warm water immediately after use. Maurten gels are water-soluble, so residue is generally straightforward to clear, but allow it to dry fully before refilling to avoid diluting the gel.
For athletes carrying multiple gels over a long effort, a single flask reduces bulk, eliminates the need to open sachets on the move, and cuts down on packaging waste across a training block.
No. The Gelflask is an accessory with no active ingredients. All nutritional value comes from the gel you fill it with.

Been using this for a few months now during long ride days. So much easier than fumbling with sachets when you're at 180bpm and your hands are sweaty. Fills up quickly before a race, dispenses smoothly. Does exactly what it's supposed to.

Signed up for my first marathon and my coach suggested sorting out my fuelling kit early. This has been brilliant during training — no more sticky gel sachets in my pocket, no wrappers to deal with mid-run. The gel flows out really cleanly even when I'm tired.

Does what it says, would buy again.

Works really well once broken in, but the nozzle was pretty stiff for the first few uses — had to bite it quite hard to get a good flow on the move. Loosened up after a week or so. Once it's sorted it's brilliant for longer triathlon efforts. Just worth knowing going in.

I used to dread fuelling during races because tearing open gels while running felt like a disaster waiting to happen. This flask just clips to my vest and I take a controlled sip whenever I need it. Genuinely removes a stressor on race day.
