Kilometer 80. Three gels down. Your stomach is over it, you're not looking forward to number four, and you still have two hours to ride. That moment is the real problem with gels. Not the formula on paper. It's the question of whether you can still get them down after three hours.

That is why more cyclists are switching to a clean-label fruit energy bar as a solid foundation for their fueling. The complete guide to energy bars for cycling provides the full framework. Here, I delve into the comparison itself: what is the difference between a gel and a fruit bar, what does research say about fruit as a carbohydrate carrier, how to read a label, and how to build a realistic hourly schedule with them.

What exactly is a clean-label fruit energy bar?

A clean-label fruit energy bar is fruit-based sports nutrition with a short ingredient list where every item is recognizable as real food, developed to be eaten during exertion. No synthetic dyes. No artificial flavors. No synthetic preservatives. What is on the packaging is what is inside.

The Eagle fruit performance bar contains 80 g of carbohydrates per 100 g, in a 2:1 glucose-fructose ratio. One 25 g bar provides 20 g of carbs. Vegan, gluten-free, and lactose-free. Produced in a certified Belgian production facility (BRCGS Food Safety, ACS).

The functional difference from a standard gel is not in the goal or the amount of carbs. It is in the carrier. For a gel, this is usually a concentrated syrup with synthetic additives. For a fruit bar, it is fruit.

I am not claiming to have invented the fruit bar. It already existed. What I did do: combine the flavor level of a three-star kitchen with botanicals in a bar that you effectively eat during exertion, rather than after.

What is in a gel that is not in a fruit bar?

Look at any random gel and you will often find more than ten ingredients. Maltodextrin or glucose syrup as a base. Synthetic preservatives. Lab-created flavors that mimic fruit. Sometimes sugar alcohols. That is a formula designed for performance on paper, not for transparency on the label.

For some riders, that is not a problem. For a growing group, it is, and the objections are concrete:

• They want to know what they are consuming without having to decode a label.
• They don't want three hours of sweeteners and syrup on an empty stomach.
• Vegan riders run into hidden animal-derived ingredients. Gelatin as a binder and lactose in recovery products are in more brands than you might think.
• Those who eat gluten-free want certainty, not a footnote.

The Eagle bar is vegan, gluten-free, and lactose-free by design, not as an exception in the range. No gelatin. No lactose. That is not an extra for a niche; it is simply how the formula is built.

How do you read a label as a cyclist?

Ingredients are always listed in order of weight. The first ingredient weighs the most. If maltodextrin or glucose syrup is at the top, that is the core of the product. If fruit pulp is at the top, fruit is the core. That single line tells you more than the entire front of the package.

Signs that you have a highly processed product in your hands:

• More than five ingredients, two or more of which are synthetic
• E-numbers in the 200 or 300 series (preservatives and antioxidants)
• "Flavor" or "nature-identical flavor"—those are lab products
• Modified starch as a filler
• Gelatin as a binder, meaning not vegan
• Sugar alcohols like maltitol or sorbitol, which remain in the gut

A clean-label product publishes the full list without footnotes. If you want to see how stark that difference can be, compare it for yourself: fruit energy bar versus Haribo candy, the label investigation. Two products that both say "fruit" on the front and something very different on the back.

Why is 2:1 glucose-fructose the basis?

Your gut has a ceiling. Glucose enters via one transport channel, and that channel is full at around 60 g per hour. Fructose uses a second, separate channel. If you put both to work at the same time, the ceiling shifts to about 90 g per hour. That is the whole idea behind the 2:1 ratio: opening two doors instead of one.

Currell and Jeukendrup (2008) tested this with eight well-trained cyclists. Those who ingested glucose and fructose in a 2:1 ratio rode the time trial two hours into the ride 8% faster than those who got the same amount of carbs from glucose alone. Same amount of carbohydrates, different result. The explanation: your body burns more carbs from an external source with the 2:1 mix, which spares your own glycogen for longer.

The 60 to 90 g of carbs per hour and the 2:1 ratio are general guidelines from sports nutrition for exertion of two hours or longer. They belong to your total intake per hour, from all sources combined, not to a single product. The Eagle bar is built around that ratio: pear, mango, raspberry, and cherry naturally provide glucose and fructose close to 2:1, and that ratio is refined in the formulation so that every bar falls within that range.

Does fruit as a carrier work as well as a synthetic gel?

That is the question that matters, and there is direct research on it. Too et al. (2012) had eleven trained runners run for 80 minutes plus a 5 km time trial, once with raisins as a carbohydrate source and once with commercial sports chews. Result: the same performance, the same blood glucose, no difference in stomach issues between the two. The natural source did result in a lower insulin spike and more fat burning.

Rietschier et al. conducted a similar test on the bike, with raisins versus sports candies over two hours plus a 10 km time trial. Also there: equal performance. The difference was in the athletes' preference, who scored the natural source higher on taste.

Conclusion: fruit as a carbohydrate carrier during exertion is not an experiment and not romanticism. It is functionally equivalent to a synthetic formula. That is exactly the premise I am building on, with the ratio accurately calibrated, the format at 25 g, and the taste at a culinary level rather than a candy level.

What do we know about stomach issues during exertion?

Stomach issues are not a peripheral phenomenon in endurance sports. The review by de Oliveira, Burini, and Jeukendrup (2014) in Sports Medicine lists the figures: depending on the sport and context, 30 to 90% of endurance athletes report issues during exertion. In Ironman races, this rises to 93% for at least one symptom, with 31% describing it as severe. For cyclists, the hunched-over position adds another factor.

The same review lists the factors associated with these issues in research:

• A high sugar concentration in what you drink, causing your stomach to empty more slowly
• Certain sugars and sweeteners that remain in the gut and ferment
• Fat, protein, and fiber, which slow down gastric emptying
• Dehydration, which worsens blood flow to your gut and therefore nutrient absorption
• Getting all carbs from a single source instead of spreading them out

It is important to be honest about what this does and does not mean. I am not claiming that a bar prevents or solves stomach issues. That is not a claim I am allowed or want to make. What I can say is this: these are the factors that come up in research, and you can check for yourself which of these are in your current nutrition. Sugar alcohols, a sky-high sugar concentration in your bottle, getting everything from a single source. If you want to switch sources based on that, you have a well-founded reason to do so.

Fruit energy bar versus energy gel: the comparison

Texture is not a minor detail. A gel requires technique: tearing open a pouch, sucking it empty, rinsing with water, and finding somewhere to put the empty pouch. In a peloton or halfway through a descent, that is not exactly neutral. In the cold, a gel becomes syrupy; in the heat, it becomes watery, and once open, it has to be consumed.

A 25 g bar works differently. Two or three bites, no forced timing, no water needed, and the rest can go back into your back pocket. You chew it away in pieces, which slightly spreads out your intake over a few minutes. And it remains edible in the cold, which is not just a theoretical advantage in Flanders in March.

When is a gel actually the better choice?

I'm not going to pretend that a bar is always better. That is not true, and you will notice it yourself on your first ride.

A gel is the better choice if you are in the final and have your hands full dealing with the wheel in front of you. Above 90% of your maximum exertion, you don't want to be chewing. In a sprint, on a steep final climb, or in an attack, a gel is more practical, simply because you get it all down in one motion. During team work where bottles are passed, a gel is also easier to hand off than a bar.

That is how I use it myself and how I see it work for riders: the bar is your stable base layer for the first few hours, the gel is your option for the sharp part at the end. Both count toward your total. Energy bar versus energy gel: when to use which breaks down that consideration by scenario.

How to build your hourly schedule on the bike

Carbohydrates during exertion never come from a single source. Sports drink is your primary source, bars are the solid component on top of that, and a gel is optional for the final.

Calculating with sports drinks of 6 to 8% carbs:

• 500 ml provides 30 to 40 g of carbs
• 750 ml provides 45 to 60 g of carbs
• An 800 ml bottle with a 2:1 mix provides up to approx. 60 g of carbs

One Eagle bar adds 20 g of carbs to that, in the same 2:1 ratio. This is how you build your hour:

• Around 60 g per hour: 1 bottle of 500 to 750 ml plus 1 bar per hour.
• Around 75 to 90 g per hour: 1 bottle of 750 to 800 ml with a 2:1 mix plus 1 to 2 bars per hour.
• Final: optionally 1 gel for the sharpest section. The bars remain your base layer.

Keep it to a maximum of 1 to 2 bars per hour. More is not realistic; your stomach won't process four bars per hour at a high pace. Bars do not replace your sports drink; they complement it.

There is confusion about timing, so let's be clear: don't wait until 45 or 60 minutes have passed. Start within the first 20 to 30 minutes, even if it still feels easy. Your gut needs time to get going, and waiting until you are empty means you will never make up the deficit. Above approximately 70% of your VO2max, you consume carbohydrates faster than fat burning can keep up. In addition, drink before you feel thirsty, as dehydration worsens your absorption. A practical application for long rides is in the ideal energy source for your bike ride.

Which bar at what moment?

The range is built around the same carbohydrate profile, with variants for different moments in the ride.

Energy is the basis: fruit plus botanicals, 20 g of carbs in 2:1, for use during the ride. This is the bar that covers the majority of your hours.

BOOST is the same bar with 50 mg of caffeine, intended for the final. Furthermore, there are variants with rhodiola, and variants with amaranth and sodium for long distances. Those ingredients are in there, they are researched, and I am not going to attach an effect to them that I cannot promise. Regarding caffeine: the state of research is in caffeine and sports performance, the science behind every watt.

Contains caffeine. Not recommended for children, pregnant women, or caffeine-sensitive persons.

Does this also apply to runners and triathletes?

Yes. Your gut doesn’t know which sport you are doing. The 2:1 ratio and the target figures of 60 to 90 g per hour apply to any endurance sport where you are riding at a steady tempo for longer than two hours. Too et al. (2012) even conducted their research into fruit as a carbohydrate source with runners, not cyclists.

For runners, there is one additional consideration. The vertical impact of running puts more stress on your stomach than the flat, fixed rhythm of cycling, making problems arise more often and more quickly. That makes your choice of source there all the more important, rather than less. The same argument applies to triathletes, as they have to finish a run after swimming and cycling with whatever is still in their stomach.

One product. Three disciplines. Same math per hour.

No gel. No brick. Fuel.

The "energy bar" category is broad and, as a result, has become almost empty. Chocolate bars with a sports logo. Cereal bars with added vitamins. Protein bars masquerading as sports nutrition. None of those products are built to be eaten while you are riding at tempo.

A fruit performance bar is something else. Concentrated carbohydrate fuel in solid form, fruit-based, 2:1, 0% artificials, vegan and gluten-free, with a texture that works while you ride. If your stomach starts acting up after two hours, if you don't want to start on a fourth gel after three, or if you simply want to know what you are consuming: then this is your source.

During exertion. Period. Fuel your flight.
