If you've been reaching for a gel mid-run and squinting at the ingredient list wondering what half of it even is, you're not alone. A lot of endurance athletes are starting to ask a pretty straightforward question: does fuelling actually need to be this complicated?
The short answer is no. Your body doesn't care whether its carbohydrates come wrapped in a foil sachet or out of a jar of honey. What it cares about is getting the right amount of fast-available energy at the right time. And there are some brilliant, entirely natural sources of carbohydrate that have been doing exactly that for a long time... long before the sports nutrition industry upped the pace.
Here's a look at some of the best natural carbohydrates for endurance sports, how to use them practically, and what to add to get the most out of them.
Honey
Honey is probably the most well-known natural gel alternative, and for good reason. It's a mix of glucose and fructose, which means it delivers carbs through two different absorption pathways simultaneously. That's actually the same principle behind most high-end energy gels: a dual-carb blend to maximise uptake during prolonged effort.
A standard squeezy bottle of runny honey holds around 280g of carbohydrates. It fits neatly in a jersey pocket or running vest, and you can take a small swig whenever you'd normally reach for a gel. No packaging to shove in your pocket afterwards, no wrapper to drop on the trail.
There is also evidence that suggests honey is as effective as gels for endurance sports!
Top tip: Mix a little sea salt into your honey before a long ride or run. You'll get natural electrolytes (sodium from the salt) without adding anything artificial. It's a proper natural energy gel in a squeeze bottle.
Raw or Manuka honey is fine, but for exercise, plain runny honey is usually better, it flows easier and gets into your system faster.
Maple Syrup
Maple syrup sits in a similar space to honey: it's mostly sucrose (which your body breaks down into glucose and fructose), it's natural, and it has a slightly thinner consistency that some people find easier to stomach mid-effort.
A small flask of maple syrup is easy to carry, and the taste is a lot more pleasant than synthetic gels after an hour or two in the saddle. Some cyclists swear by it. The key is portion size: about 30–40ml gives you roughly 20–25g of carbohydrate, which puts it in the same ballpark as a standard gel.
Like honey, the simple addition of a pinch of salt turns it into something much more balanced. If you want to go a step further, mix it with a small amount of coconut water for a homemade natural electrolyte drink that really does the job.
Bananas
Bananas are the original endurance fuel. There's a reason they're handed out at virtually every marathon and sportive in the country. They're rich in natural glucose, fructose, and sucrose, and they come with a bit of fibre, potassium, and B vitamins built in.
They're not the easiest thing to eat at race pace, but for training or lower-intensity efforts they're hard to beat. Half a banana every 30–40 minutes keeps energy levels steady and sits well in the gut for most people.
The main trade-off is convenience. You need somewhere to put a banana, and once you've opened it, you're committed. But for a long ride with a jersey pocket to spare, they're a simple, cheap, and effective natural carbohydrate source.
Dates
Dates are underrated as endurance fuel. They're dense in natural sugars, mostly glucose and fructose, and have a soft, chewy texture that's easy to eat on the move. Medjool dates are the gold standard: large, naturally sweet, and genuinely satisfying.
A couple of dates every 20–30 minutes gives you a steady carbohydrate hit, and they're small enough to keep in a zip-lock bag in your pocket. Some athletes roll them with a bit of sea salt and coconut flakes for a DIY energy ball that covers carbs, sodium, and electrolytes all at once.
They're also good for gut health, which matters on longer efforts when your digestive system is under a bit more stress. Be careful on long hot days, they can get a bit sweaty.
Cane Sugar
Plain cane sugar, or sucrose, is worth mentioning because it's one of the most direct natural carbohydrate sources you can use. Some endurance athletes dissolve it into water with a pinch of salt and a squeeze of lemon for a basic homemade sports drink that costs almost nothing to make.
It doesn't have the trace nutrients of honey or dates, but it's fast-acting, easy to digest, and completely free of anything synthetic. If you're making your own energy drinks at home, cane sugar dissolved in water gives you a consistent, controllable carbohydrate source that works. Mix it with coconut water too and you're golden.
The Thing All of Them Are Missing
Here's where it's worth being honest: all of these options are genuinely good sources of natural carbohydrate, but on their own, they don't fully replace what a properly formulated sports fuel does.
The two things you lose when you go full DIY are precision and electrolytes. Getting the right ratio of glucose to fructose consistently, hitting specific carbohydrate targets per hour, and ensuring you're replacing the full electrolyte profile you lose through sweat (not just sodium), these things matter more the harder and longer you go.
That's not a reason to dismiss natural whole-food fuelling. For training, steady-state efforts, and people who just want to simplify what they're putting in their body, honey and maple syrup genuinely work. But if you want whole food ingredients and sports nutrition standards, there's a middle ground.
The Hebe System
Hebe is built on exactly that idea. What if you could have clean, traceable, natural ingredients and the precision of a properly formulated endurance fuel?
The Hebe System is a carbohydrate-electrolyte powder made from four ingredients:
- Italian grape sugars — natural 2:1 ratio dual carbohydrates from Sicilian grapes
- Coconut water — natural electrolytes, rich in potassium
- Pink Himalayan salt — clean sodium replacement
- Lemon and lime juice — subtle acidity, helps reduce flavour fatigue on longer efforts
No preservatives. No sweeteners. No additives you'd need a chemistry degree to understand. Just natural, traceable ingredients formulated to the same 2:1 carbohydrate standard used by the best endurance products in the world.
It comes as a powder in a recyclable 900g pouch: 30 servings, each with around 26g of carbohydrates and a full electrolyte profile. You fill your own reusable flask or bottle before a run or ride using the Hebe Scoop. No single-use gel wrappers. No plastic sachets heading to landfill.
It's the same thinking as going for honey or maple syrup: natural ingredients, simpler approach, nothing unnecessary, but with the formulation dialled in so you're not guessing at carb ratios or electrolyte balance mid-marathon.
Starter kits from £39, including two reusable Hebe Flasks or Bottles and a Hebe Scoop.
If you've been looking for a cleaner way to fuel without sacrificing performance, it's worth a try. There's a 30-day money-back guarantee, so there's nothing to lose except the gel wrappers.
