Precision Fuel 90g Carb Gel - Original (Single)

This is a Single Precision Fuel 90g Carb Gel. Most energy gels give you 20 to 30 grams of carbohydrate in a single-use sachet that you tear open, squeeze down, and throw away. That approach works fine for shorter efforts, but for athletes training or racing for several hours, it creates a real problem. You end up carrying handfuls of individual sachets, trying to tear them open while running at pace or riding in a pack, and chasing down each one with fluid because they are sticky and hard to swallow without something to wash them away.

The PF 90 Gel solves all of that in one product.

Nicknamed the Jumbo Gel, the PF 90 is a 153g resealable pouch that delivers 90 grams of carbohydrate in a single carry. It is the same mild-tasting, easy-to-digest formula as the popular PF 30 Gel, scaled up three times and packaged in a format built for long-duration endurance sport. One pouch, one pocket, no mess, no fuss.

Developed by Precision Fuel and Hydration, a sports science brand trusted by IRONMAN champions, professional triathletes, and elite endurance athletes worldwide, the PF 90 Gel is built around the research showing that athletes who fuel consistently and predictably across long efforts perform significantly better than those who rely on guesswork or convenience.

How to Use

Open the resealable cap and squeeze or sip directly from the pouch. For efforts lasting 60 to 90 minutes, aim to consume roughly 30g (one third of the pouch) per hour. For higher-intensity or longer efforts, consumption can be increased up to 90g per hour in athletes who have trained gut tolerance. Take smaller sips frequently rather than one large dose at a time for best gut comfort. Pair with a Precision Hydration electrolyte product to manage fluid and sodium separately. Store in a cool, dry place.

Why 90g of Carbohydrate in One Pouch Changes How You Fuel

The biggest practical challenge in long-distance fuelling is not understanding the science. Most experienced endurance athletes know they need carbohydrate. The challenge is actually executing a fuelling plan consistently when your hands are full, your concentration is on the effort, and you are already deep into race fatigue.

Individual sachets require tearing open one at a time, which produces rubbish you need to carry or discard, and many athletes find it genuinely difficult to keep track of how many they have taken and when. The PF 90 removes that friction almost entirely. You carry one pouch, open it once, take sips from the resealable cap throughout your effort, and close it between doses. You know exactly how much carbohydrate is in the pouch when you start and you can track your intake in thirds, each third representing roughly 30g of carbohydrate.

For athletes following a 60g per hour fuelling strategy, one pouch covers approximately 90 minutes of fuelling. For those pushing toward the upper end of 90g per hour that well-trained athletes can absorb, one pouch covers a full hour. Either way, the maths is clean and the execution is straightforward.

The Science of the 2:1 Glucose to Fructose Ratio

The carbohydrate in the PF 90 Gel comes from two sources: maltodextrin and fructose, in a 2:1 ratio. This is not a marketing distinction. It is a meaningful physiological one.

The human gut absorbs glucose via the SGLT1 transporter. That transporter has a ceiling of approximately 60g per hour. Fructose, by contrast, is absorbed via a separate GLUT5 transporter pathway. By providing both glucose and fructose together, the body can use both transport pathways simultaneously, allowing total carbohydrate absorption to reach up to 90g per hour in athletes who have trained their gut to handle it.

A gel providing only maltodextrin (glucose) cannot breach that 60g per hour ceiling no matter how much of it you take. The dual-source formula in the PF 90 Gel is what makes high-rate fuelling physiologically possible.

Resealable Cap and Micro-Dosing: A Better Way to Take On Fuel

One of the least appreciated advantages of the PF 90 format is the ability to micro-dose your carbohydrate intake. Rather than consuming 30g all at once every 40 minutes, you can take smaller sips every 10 to 15 minutes, keeping a steadier supply of carbohydrate entering the gut. This gentler, more consistent delivery is often better tolerated, particularly later in an event when the gut is under physiological stress from reduced blood flow.

The resealable cap makes this approach practical. You take a sip, close the cap, and store the pouch until the next dose. The texture is designed to flow smoothly without being too liquid or too thick, and the mild neutral flavour means it does not become difficult to consume after the first hour, which is a common complaint with more intensely flavoured gels.

An optional Bite Valve accessory is also available separately, which converts the cap into a hands-free sipping system and eliminates the need to unscrew the lid during movement.

What Is in the PF 90 Gel

The ingredient list is short: maltodextrin, water, fructose, pectin, citric acid, potassium sorbate, and calcium lactate. No artificial colours, no artificial flavours, and no unnecessary fillers. The formula is vegan, vegetarian, gluten-free, and dairy-free.

The PF 90 Gel contains no electrolytes. This is a deliberate design decision that separates it from many competitor products that attempt to bundle carbohydrate and sodium together. Precision Fuel and Hydration build their product range around the principle that fuel and hydration should be managed independently, because individual sweat rates and sodium losses vary enormously between athletes. The gel handles carbohydrate delivery and is designed to work alongside Precision Hydration electrolyte products, which allows athletes to calibrate their hydration intake based on their personal sweat profile rather than relying on a one-size-fits-all formula.

The PF 90 Gel is Informed Sport certified, meaning every batch is tested for banned substances. This makes it appropriate for competitive athletes at all levels who need confidence that what they are consuming meets anti-doping standards.

Nutritional Information (Per 153g Pouch)

Each pouch delivers 360 kilocalories (1,506 kilojoules), 90g of carbohydrate (including 36g of sugar), less than 0.1g of protein, and less than 0.1g of fat.

Who Is the PF 90 Gel For?

The PF 90 Gel is built for athletes going long. It suits runners tackling half marathons, marathons, ultras, and trail races, cyclists on multi-hour rides, triathletes racing IRONMAN or long-course events, and anyone competing or training at high intensity for more than 90 minutes who needs a practical, reliable, and easy-to-execute fuelling strategy.

It is also an excellent choice for athletes who have previously struggled with carrying and managing multiple individual gel sachets during long efforts, or those who prefer to micro-dose their carbohydrate intake rather than bolus dose every 30 to 45 minutes.

For shorter but intense efforts, the PF 90 can also be used as a standalone fuel source, with the resealable cap allowing you to use a portion and store the rest for later in the session.
