Best Energy Gels for Running Australia 2026 β Tested and Ranked
Choosing the wrong energy gel causes GI distress, energy crashes, and ruined race days. We tested every major brand available in Australia β including Australian-made options β to find what actually works for Australian runners across different distances and conditions.
Why Energy Gel Choice Matters More Than Most Runners Think
Most recreational Australian runners underestimate how significantly nutrition affects performance. Beyond the 90-minute mark, your body exhausts its stored glycogen and begins to slow β not because your legs are tired, but because your brain is starving for glucose. The right energy gel prevents this; the wrong one causes stomach cramping, nausea, and a memorable race-day disaster.
Getting nutrition right requires experimentation β what works for one runner may not work for another. But starting with gels that have the right formulation, appropriate carbohydrate concentration, and texture suited to your preferences dramatically reduces the trial and error involved.
How to Use Energy Gels Correctly
Before reviewing individual gels, understanding the basics prevents the most common mistakes:
- Start fuelling early: Take your first gel at 45-60 minutes into a run, before you feel hungry. Once you feel depleted, it is too late β gels take 15-20 minutes to absorb.
- Frequency: Most Australian sports dietitians recommend one gel every 30-45 minutes for runs over 75 minutes, targeting 30-60g of carbohydrate per hour.
- Water: Most gels (except isotonic formulas) require 150-200ml of water to digest properly. Taking gel without water causes concentrated carbohydrate sitting in your stomach β a leading cause of GI distress.
- Heat adjustment: In Australian summer conditions, electrolyte loss is significantly higher than in cooler climates. Choose gels with sodium and consider adding electrolyte gels or tablets to your nutrition plan for hot-weather events.
- Practise in training: Never take a new gel for the first time on race day. Your gut needs to adapt to processing carbohydrates while running.
Best Energy Gels Available in Australia
1. Maurten Gel 100 β Best for Sensitive Stomachs (AU$4.95 each)
Maurten's hydrogel technology remains the benchmark for runners with sensitive stomachs. The hydrogel formulation encapsulates 25g of carbohydrates in a polymer matrix that passes through the stomach to the intestines before breaking down, bypassing the stomach acid that causes GI distress with conventional gels.
The texture is distinctive β a water-jelly consistency rather than the thick syrup of most gels. Many runners find this significantly easier to consume at race pace and in hot conditions when strong sweet flavours become nauseating. The minimal ingredient list (water, maltodextrin, fructose, sodium alginate, pectin, sodium chloride, potassium chloride) appeals to runners who prefer clean nutrition.
The significant downside is price. At AU$4.95 per gel, Maurten is the most expensive option on this list. Most runners reserve it for races rather than training. Available at Running Warehouse AU, Pure Running, and ASICS stores nationally.
Best for: Runners with GI issues, marathon and ultra runners, heat racing in Australian summer.
2. Koda Energy Gel β Best Australian-Made Option (AU$2.80 each)
Koda (formerly Shotz) is an Australian-owned sports nutrition brand that has been formulating products for Australian athletes since 1995. Their gels are formulated specifically with Australian conditions in mind β the electrolyte balance accounts for the higher sweat rates common in Australian summer running.
Each 45g sachet contains 25g of carbohydrates and a solid sodium hit for electrolyte replacement. The consistency is smooth rather than thick, making them easy to take at pace. Flavours are fruit-forward with options including Cola and Cappuccino for runners who want caffeine (80mg per caffeinated gel).
At AU$2.80 per gel, Koda represents excellent value for an Australian-made product. Available at Running Warehouse AU, Pure Running, and most Australian running specialty stores. The fact that they are made in Australia means fresher stock and faster restocking than imported alternatives.
Best for: Value-conscious runners, hot-weather racing, Australian trail events, runners supporting local brands.
3. SiS Go Isotonic Gel β Best Without Water (AU$3.20 each)
Science in Sport's isotonic gel formula is unique among major brands in being genuinely designed to be consumed without water. The isotonic carbohydrate concentration matches your blood plasma concentration, allowing absorption without additional fluid. This is practically useful on trail courses where water stations are infrequent.
Each 60ml gel contains 22g of carbohydrates with a light, watery consistency that many runners prefer to thicker gels. The larger sachet size means slightly more volume to manage mid-run. Available at Running Warehouse AU, pharmacy chains, and online retailers across Australia.
Best for: Trail runners, runners who struggle to drink and run simultaneously, runners who find thick gels difficult.
4. SiS Beta Fuel β Best for Marathon and Beyond (AU$5.50 each)
SiS Beta Fuel delivers 40g of carbohydrates per gel β significantly more than standard gels β using a 1:0.8 maltodextrin to fructose ratio that research shows maximises carbohydrate absorption rate. The theoretical maximum carbohydrate absorption using multiple transport proteins is 90g per hour, and Beta Fuel makes hitting those targets with fewer gels practical.
For Australian marathon and ultramarathon runners following high-carbohydrate race nutrition strategies, Beta Fuel reduces the number of gels required per hour and simplifies fuelling logistics. The price is premium at AU$5.50 per gel, but fewer required per hour partially offsets this.
Best for: Marathon runners targeting sub-4 hours, ultra runners, athletes following high-carbohydrate race nutrition protocols.
5. GU Energy Gel β Best for Everyday Training (AU$2.50 each)
GU Energy Gels are the most widely available running nutrition product in Australia and have earned their position through reliable, consistent performance across a huge range of flavours. Each 32g gel contains 20-22g of carbohydrates with a blend of maltodextrin and fructose for dual-source energy delivery.
With over 20 flavours available in Australia β including Salted Caramel, Chocolate Outrage, and Vanilla Bean β GU offers the widest variety of any gel brand. The caffeinated options (20mg, 40mg, or Jet Blackberry at 40mg) allow runners to manage caffeine intake through their nutrition rather than requiring separate products. Available at virtually every running store, pharmacy, and sporting goods store across Australia.
Best for: Training runs, beginner runners, runners who prefer flavour variety, those on a budget.

Australian-Specific Considerations
Australian summer running demands more sodium than most gel brands account for in their standard formulations. In temperatures above 25 degrees C, sweat rates increase significantly and sodium loss can cause hyponatraemia (dangerous low sodium) in long events. Supplement standard gel use with electrolyte tablets or choose higher-sodium options like Koda for hot-weather racing.
For Australian trail events requiring mandatory gear, gels are usually the primary race nutrition. Their light weight and high caloric density make them ideal for vest pockets. The Salomon ADV Skin vest popular with Australian trail runners fits standard gel sachets in the front soft flask pockets without needing to remove the flask.

Frequently Asked Questions
How many gels do I need for a marathon in Australia?
Most Australian sports dietitians recommend one gel every 30-45 minutes from 45 minutes into the race. For a 4-hour marathon, this means roughly 6-7 standard gels (25g carbs each). In hot conditions, increase to one every 30 minutes. Using high-carbohydrate gels like SiS Beta Fuel reduces this to 4-5 gels for the same carbohydrate total.
Are Maurten gels worth the price in Australia?
For runners with a history of GI issues during races, yes. For runners with robust stomachs who have no issues with conventional gels, the premium is harder to justify for training. Most runners use Maurten for races and cheaper options (GU, Koda) for training.
Can I take energy gels without water in Australia?
Only isotonic gels like SiS Go are genuinely designed for consumption without water. Taking standard gels (GU, Koda, Maurten) without water risks GI distress from concentrated carbohydrate sitting in your stomach. In Australian heat where dehydration risk is higher, always take water with non-isotonic gels.
