If you've ever bonked at kilometre 32 of a marathon or cramped on a long Saturday ride, you've felt the cost of getting your fuelling wrong. Energy gels are designed to solve that — but with shelves full of options in Australia, choosing the right one (and timing it correctly) is harder than the run itself.
This guide breaks down everything Australian endurance athletes need to know in 2026: what energy gels actually do, when to take them, how many you need, and how the most popular options in Australia compare — including Japanese amino shots and the new wave of natural maple sap fuel.
What is an energy gel, exactly?
An energy gel is a concentrated dose of fast-absorbing carbohydrates — usually 20–30g per sachet — designed to top up your muscle glycogen stores during exercise lasting longer than 60–75 minutes.
Your body stores about 90 minutes' worth of usable carbohydrate as glycogen. Once that runs out, performance drops sharply. This is what runners call "the wall" or "bonking." Energy gels are the easiest way to keep glycogen topped up while you're moving, without the bulk of solid food.
A typical gel delivers:
- 20–30g carbohydrates (glucose, fructose, sometimes maltodextrin)
- 80–120 calories
- 0–100mg sodium (some include electrolytes)
- 0–100mg caffeine (optional, in caffeinated versions)
The right gel depends on your goal, your stomach, and how long you'll be out there.
When should you take an energy gel?
The biggest mistake Australian runners make isn't choosing the wrong gel — it's taking them at the wrong time.
The general rule: 30g of carbs per hour
Sports nutrition research (Jeukendrup, 2014; the most-cited endurance fuelling study) shows trained athletes can absorb roughly 30–60g of carbohydrate per hour during exercise. That translates to one gel every 30–45 minutes for most people.
Practical timing
- 30 minutes before your hard session: one gel + 200ml water
- Every 30–45 minutes during efforts longer than 75 minutes
- Sip water with every gel — solo gels are harder to absorb and more likely to upset your stomach
Race-specific guidance
| Event | Recommended gels | Total carbs |
|---|---|---|
| 5K / 10K | 0 | under 60 min — not needed |
| Half marathon | 1–3 | 25–75g |
| Marathon | 4–8 | 100–200g |
| 100km cycling | 4–6 | 100–150g |
| Olympic triathlon | 2–4 | 50–100g |
| Ironman 70.3 | 6–10 | 150–250g |
These are starting points. Heavier athletes, hotter conditions, and harder efforts all push you toward the higher end.
The three categories of energy gels available in Australia
Most Australian sports nutrition shops carry three distinct types of energy gels. Knowing which category you need is the first decision.
1. Synthetic carb gels (the supermarket standard)
These are the gels you'll find on most Australian shelves. They use maltodextrin and synthetic glucose-fructose blends, often with added caffeine, sodium, and artificial flavours.
✓ Pros: Fast absorption, predictable carb delivery, widely available.
✗ Cons: Sharp glucose spike followed by a crash if mistimed. Some athletes get GI upset on long efforts. Often heavily sweetened.
2. Natural maple sap gels (the new wave)
A newer category gaining traction with ultra-runners and triathletes. These gels use maple sap as the main carbohydrate source — naturally containing glucose, sucrose, and over 65 minerals.
✓ Pros: Smoother energy release than synthetic gels (no sugar crash), gentler on the stomach, vegan, no artificial sweeteners. Tastes like food, not a supplement.
✗ Cons: Slightly slower onset. Less common in Australian retail — usually only available online from specialty importers.
The standout in Australia is yohemite Vegan Energy Gel — 100% Canadian maple sap, used by Korean trail runners and now stocked by momentum for Australian endurance athletes.
3. Amino-based energy shots (the Japanese approach)
Japan has a different philosophy on race-day nutrition. Instead of pure carbohydrate, Japanese pro athletes often use amino acid shots before, during, and after races — designed to support muscle recovery and reduce fatigue.
✓ Pros: Excellent for muscle recovery in long events, helps reduce delayed soreness, doesn't sit heavy in the stomach.
✗ Cons: Lower carb content than traditional gels — pair with carb-based fuelling for events over 90 minutes.
The most respected option is AminoVITAL 2500 — 2,500mg of essential amino acids per shot, used at Japanese marathons and triathlons.
How to choose the right energy gel for your event
🏃 Half marathon (Sydney, Melbourne, Brisbane Half)
You need 1–3 gels and a clean carb source that's easy on the stomach. A maple sap gel like yohemite Vegan Energy Gel works well because the longer release means no second-half crash.
Race plan:
- 30 min before start: 1 gel + 250ml water
- 8km mark: 1 gel
- 16km mark (optional): 1 gel if you tend to fade in the final 5km
🏃♀️ Marathon (Sydney, Melbourne, Gold Coast)
You'll need 4–8 gels and a bigger plan. Mix natural and synthetic if you've trained on both.
Race plan:
- 30 min before start: 1 gel
- Every 30–40 minutes from km 8 onward
- For ultra-marathons (50km+), pair gels with AminoVITAL 2500 to support recovery while you're still moving
The yohemite Vegan Energy Gel 5-Pack covers a full marathon for most runners, with one or two spares.
🚴 Long-distance cycling (Bobbin Head, Three Peaks)
Cyclists tolerate carbs better than runners because the impact is lower. You can take more gels per hour without stomach issues. Most Australian cyclists go through 4–6 gels on a 4-hour ride, plus a sports drink for hydration.
A maple sap gel is ideal here — the gentler release matches the longer effort better than a sugar spike.
🏊 Triathlon (Noosa, Mooloolaba, Sydney)
The bike leg is your main fuelling window. Aim to take 2–4 gels on the bike, then 1–2 more on the run. Choose gels that don't require sips of water — you may have only your bottles.
Vegan energy gels in Australia
Most synthetic gels on the Australian market are technically vegan, but many use artificial flavours or sweeteners that vegans prefer to avoid. The cleaner option is a maple sap–based gel.
yohemite Vegan Energy Gel is the cleanest vegan option momentum stocks: 100% Canadian maple sap, no artificial flavours, no synthetic sweeteners, no animal-derived ingredients. It's also the choice of vegan Korean ultra-runners.
Energy gel FAQs (Australian athletes)
How many energy gels do I need for a half marathon?
Most runners take 1–3 gels for a half marathon — one before the start and one or two during. If you finish in under 75 minutes, you may not need any. If you tend to fade in the last 5km, add one at the 16km mark.
Do energy gels actually work?
Yes — but only if your body is trained to use them. Your gut needs to be conditioned to absorb high-carb fuel during exercise. Practise with the same gel you plan to race with on at least three long training sessions before race day.
Why do energy gels upset my stomach?
The most common cause is taking a gel without water. Concentrated carbohydrate without fluid pulls water into your gut, causing cramps and nausea. Always sip 100–200ml of water with every gel.
Can I take energy gels for hiking or hot yoga?
Energy gels are designed for sustained aerobic effort over 60+ minutes. For shorter sessions or low-intensity activities, you'll likely do fine on a regular meal beforehand. For long hikes (4+ hours) or high-intensity events in heat, gels can help maintain blood sugar.
What's the difference between an energy gel and an energy bar?
Bars contain protein and fat in addition to carbs, which slows absorption — better between sessions or for longer efforts where you can stomach solid food. Gels are pure carb, designed for fast absorption during high-intensity work.
Are natural energy gels really better than synthetic?
It depends on your goals. Synthetic gels deliver carbs slightly faster, which matters for elite athletes pushing the upper limits of carb absorption. For most recreational and competitive runners, the smoother release of natural maple sap gels makes them easier to tolerate over long efforts.
Build your race-day fuelling plan
Energy gels aren't magic — they're a tool. The athletes who use them best:
- Train with the exact gel they'll race with. No new gel on race day. Ever.
- Pair every gel with water. Non-negotiable.
- Time them by the clock, not by feel. By the time you feel hungry on a long run, you're already behind.
- Stack gels with electrolytes for events over 90 minutes — try yohemite Water Electrolyte Tablets for cramp prevention on humid Sydney summer rides or Brisbane runs.
