The Best Natural Energy Gels for Australian Endurance Athletes in 2026
Most energy gel comparisons stop at flavour and calories. That is not enough.
We compared the products Australian endurance athletes actually see at run shops and aid stations. We looked at carbohydrate per gel, sodium, ingredient base, added sweeteners, preservatives and the job each product is built to do.
Updated 25 August 2026. Product formulas can change, so check the current pack before racing.
what does natural energy gel actually mean?
There is no single useful definition printed across the category. One brand may use fruit juice on a maltodextrin base. Another may use glucose and fructose with a gelling system. A third may build the gel from rice, fruit, dates or maple syrup.
Natural does not automatically mean better for performance or easier on every stomach. The useful questions are more direct:
- How many grams of carbohydrate are in one serve?
- Which carbohydrate sources are used?
- How much sodium is included?
- What else is in the formula?
- Can you tolerate the product at race intensity?
- Can you repeat it for the full event?
the honest comparison
| gel | carbohydrate | sodium | main fuel base | what stands out |
|---|---|---|---|---|
| 2THRV Whole Food Fuel Gel | 30g | 250mg | maple syrup, dates and berries | five ingredients, no maltodextrin, gums, artificial sweeteners or added preservatives |
| Spring Energy Awesome Sauce | 28g | 45mg | apple, rice, maple syrup, sweet potato and added oils | real-food formula with 7g fat per serve and published third-party testing |
| Maurten Gel 100 | 25g | check current pack | glucose and fructose in a hydrogel system | six ingredients, no colours, flavours or preservatives |
| PURE Fluid Energy Gel | varies by product, up to 30g | varies by product | maltodextrin, water and fruit juice | fluid texture with natural flavour positioning, plus preservatives in current formulas checked |
| SiS GO Isotonic Gel | 22g | 20mg | maltodextrin | fluid isotonic format, with gums, sweetener and preservatives |
| GU Original Energy Gel | 21 to 23g | 60 to 125mg | maltodextrin and fructose | wide flavour range, dual-source carbohydrate and caffeine options |
| KODA Energy Gel | 29.8g | check current flavour | maltodextrin | Australian option with a liquid texture and simple performance focus |

best whole-food energy gel
For athletes specifically looking for fuel built from recognisable food ingredients, 2THRV and Spring Energy are the clearest options in this comparison.
They are not the same product. Spring Awesome Sauce currently combines fruit, rice and maple syrup with MCT and avocado oils. That creates a higher-calorie gel with 7g of fat. 2THRV keeps the focus on carbohydrate and electrolytes, with 30g carbohydrate, 250mg sodium and 0.1g fat.
That makes 2THRV the cleaner fit for athletes who want a food-first gel without adding a meaningful fat load during harder running or cycling.
best minimalist performance gel
Maurten deserves a fair description. Its current Gel 100 is not a maltodextrin gel. It uses water, glucose, fructose, sodium alginate, gluconic acid and calcium carbonate. It is a short formula built around Maurten's hydrogel technology.
If you want a highly engineered gel with a neutral flavour and strong race availability, it is a serious option. If you want the carbohydrate itself to come from food ingredients, it is a different category to 2THRV.
best fluid conventional gel
SiS GO, PURE Fluid and KODA all lean into a thinner texture. That matters. Some athletes struggle with thick gels late in an event, especially in heat.
The trade-off is formula preference. The current products checked here use maltodextrin as the main carbohydrate base. SiS and the PURE formulas checked also list gums, sweeteners or preservatives depending on the product.
which gel is easiest on the stomach?
No honest brand can answer that for every athlete.
Exercise-related gut symptoms are influenced by intensity, heat, hydration, carbohydrate dose, solution concentration, mechanical impact and what you ate before the session. A product can have a short ingredient list and still fail if you take too much too fast. A more engineered gel can work perfectly for an athlete who has practised with it.
The strongest general strategy is to choose a formula you can repeat, then train your gut with the exact product, dose, fluids and intensity you plan to use on race day. A 2023 systematic review found that repeated carbohydrate feeding during training may reduce discomfort and improve carbohydrate tolerance, although the evidence is not identical across every study.

why sodium matters in australian conditions
Sweat losses vary massively between athletes. The number on a gel is only one part of the plan because sodium can also come from drink mix, capsules and food.
Still, the difference between 20mg and 250mg per gel is material. If you train in Australian heat, calculate the total sodium and fluid in your complete hourly plan. Do not assume every product sold as endurance fuel is designed to cover the same job.
our pick
If your priority is familiar food ingredients, a full 30g carbohydrate serve and meaningful sodium in one pouch, 2THRV Whole Food Fuel Gel is the strongest all-round fit in this comparison.
