Maurten Gel 100 Review: Is the Hydrogel Hype Worth It?

If you've spent any time in the running community over the last few years, you've heard about Maurten. The Swedish sports nutrition brand burst onto the scene with a bold claim: their hydrogel technology could deliver more carbohydrates to working muscles with significantly less gastrointestinal distress than traditional gels. Elite athletes adopted it rapidly — the list of world-record holders and major marathon winners fuelling with Maurten is long and impressive. But does the Gel 100 actually deliver for the everyday runner? This review breaks down the science, the real-world experience, the taste, and whether it's worth the premium price for Australian runners.

What Is Maurten Gel 100?

Maurten Gel 100 is a hydrogel energy gel containing 25 grams of carbohydrates. The "100" refers to the kilojoule content (100 kcal / approximately 420 kJ). It comes in an unflavoured, slightly sweet formulation with a distinctive gel-like texture that's unlike any other running gel on the market. The product contains:

25g carbohydrates (maltodextrin and fructose in a 0.8:1 ratio)
Sodium (55mg)
No artificial flavours, colours, or preservatives
No caffeine (a separate caffeinated version, the Gel 100 CAF 100, contains 100mg caffeine)

Available in Australia through Maurten's direct website, selected running specialty stores, and online via iHerb AU. Price sits around $5.50–$6.50 AUD per gel depending on the retailer.

The Hydrogel Technology: What Does It Actually Do?

This is the core of Maurten's value proposition, and it's worth understanding properly before deciding whether the price premium is justified. Traditional energy gels deliver carbohydrates in a highly concentrated solution. When this solution hits the stomach, the body needs to dilute it before it can be absorbed — drawing fluid from surrounding tissues to equalise the concentration. This osmotic effect is the primary driver of GI distress in many runners: bloating, cramping, nausea, and the urgent need to find a bush at kilometre 28. Maurten's hydrogel addresses this through encapsulation. When the gel is mixed with the acidic environment of the stomach, the alginate and pectin in the formula form a gel matrix around the carbohydrates. This slows their release from the stomach into the small intestine, reducing the osmotic stress and allowing for more gradual, comfortable absorption. The result — in clinical studies Maurten references and in independent research — is that carbohydrates from Maurten gels are absorbed at comparable rates to standard gels, but with significantly lower rates of GI symptoms in susceptible athletes. A 2019 study published in the International Journal of Sport Nutrition and Exercise Metabolism found that hydrogel carbohydrate delivery resulted in higher carbohydrate oxidation rates and less GI discomfort compared to a carbohydrate-electrolyte drink at matched doses. Maurten's proprietary studies show similar outcomes, though independent replication is ongoing. The key nuance: if you've never had GI issues with standard gels, the benefit may be less pronounced for you. Maurten's greatest advantage is for runners who are GI-sensitive — a substantial and often under-catered-for group.

Texture and Taste: The First-Time Experience

Let's be honest — the first time you open a Maurten Gel 100, you're going to find the texture surprising. It's genuinely different from every other gel you've tried. Rather than a thick, sticky syrup, it has a more substantial, almost custard-like consistency. Some people love it immediately. Others need a run or two to adjust. The flavour is very mild — slightly sweet with no artificial aftertaste. For runners who find the intense sweetness of gels like GU or High5 nauseating after 20km, Maurten's near-neutral flavour profile is a revelation. Consuming it mid-run is straightforward. The gel comes out of the packet easily (even with cold or slightly sweaty hands), and the texture means there's less of the messy dribbling that plagues thinner gels. The gel can be taken without water — Maurten states the hydrogel can form in the stomach without additional fluid — though drinking water alongside it, as you would with any nutrition on the run, is still sensible. Verdict on taste and texture: Unusual at first, then genuinely enjoyable. The mild flavour is a standout advantage for long runs and late-race fuelling where flavour fatigue is a real concern.

Performance Testing: Long Runs and Race Day

Testing a gel properly requires more than a single run. Meaningful assessment comes from sustained use across different session types and conditions. Easy long runs (90–150 minutes): The Gel 100 performs cleanly during easy efforts. There's no GI distress, no sugar rush and crash, and the 25g carbohydrate dose is appropriate for the 45-minute fuelling interval most coaches recommend. Energy delivery feels smooth and sustained. Marathon pace sessions: At higher intensities, the difference between GI-friendly and GI-unfriendly gels becomes more pronounced. The Maurten Gel 100 holds up well — no cramping, no bloating, and energy delivery that doesn't feel like it spikes and drops. When running at 4:30–5:00 min/km pace for extended periods, stomach comfort is noticeably better than with many conventional gels. Hot conditions: Australian summer running puts the GI system under extra stress. Heat redirects blood away from the gut to the skin for cooling, which reduces digestive efficiency and increases the risk of GI upset from concentrated nutrition products. The hydrogel technology is particularly valuable here — the reduced osmotic load is more significant when the gut is already under heat stress. Ultra-distance use: At 4+ hours of running, flavour fatigue becomes a significant issue. Many runners find they can no longer stomach sweet gels in the final stages of an ultra. Maurten's near-neutral flavour holds up far better in this regard than most competitors. Several prominent Australian ultra runners use Maurten as their primary gel for this reason.

Carbohydrate Delivery: Is 25g Enough?

At 25g of carbohydrates per gel, the Gel 100 delivers less carbohydrate per packet than several competitors. SiS Beta Fuel gels offer 40g, Maurten's own Gel 160 offers 40g, and GU Energy Gels offer 20–21g. For runners targeting 60g of carbohydrate per hour — the standard recommendation for efforts under 2.5 hours — you'd need approximately 2.4 Gel 100s per hour. In practice, most runners take one gel every 25–30 minutes, which lands around 50–60g per hour. This works fine for the majority of runners. For runners targeting 90g per hour (the upper threshold achievable with dual-source carbohydrates and trained gut absorption), the Gel 100 alone is insufficient. You'd need to combine with additional carbohydrate sources or switch to the Gel 160 or Maurten Drink Mix 320 for the highest intake rates. Practical takeaway: For runners in the 60g/hour range, the Gel 100 is appropriately dosed. For high-carb fuelling strategies (80–90g/hour), consider the Gel 160 or a combination approach.

Maurten Gel 100 vs Gel 100 CAF 100

Maurten offers a caffeinated version of the Gel 100 — the CAF 100 — containing 100mg of caffeine alongside the same 25g of carbohydrates. The caffeine is delivered through the same hydrogel matrix, which theoretically provides smoother absorption than standard anhydrous caffeine. The taste is identical to the non-caffeinated version, which means even the caffeinated gel is palatable late in a race. When to use the CAF 100: The most common strategy is to use non-caffeinated Gel 100s for the bulk of a race, then switch to CAF 100s in the final 30–40% of the effort when natural fatigue is accumulating and the adenosine-blocking effects of caffeine provide the greatest benefit. For a marathon runner, this might mean switching from Gel 100 to CAF 100 from the 28–30km mark onward. For a half marathon, the last 5–7km.

Price vs Value: The Honest Assessment

At $5.50–$6.50 AUD per gel, Maurten Gel 100 is among the most expensive running gels available in Australia. Comparable mainstream gels (GU, High5) retail for $3–$4. For a marathon requiring 8–10 gels, the cost difference is approximately $20–25 per race. For training runs, where you might use 3–5 gels per long session over a 16-week training block, the additional cost is meaningful — potentially $60–80 more than budget alternatives across a full marathon preparation. Whether this premium is justified depends on your specific situation: The premium IS justified if:

You have a history of GI distress during races or long runs
You're preparing for a key race where GI issues could cost you more than the price difference
You've tried multiple conventional gels and found them all problematic
You're running in hot conditions where GI sensitivity is heightened

The premium may NOT be justified if:

You've never had GI issues with standard gels
You're primarily using gels for training runs where stakes are lower
Budget is a significant constraint

A practical middle ground: use Maurten for races and key training sessions, and use a lower-cost gel for standard long runs. This captures the benefit where it matters most while managing cost.

Who Is This Gel For?

Ideal users:

GI-sensitive runners at any distance
Marathon and ultra-marathon runners doing sustained fuelling
Runners in hot Australian conditions (summer road running, trail ultras)
Athletes who find conventional gel sweetness intolerable
Elite and sub-elite runners where every marginal advantage counts

May not be the best fit for:

Runners who've never had GI issues and want to keep costs low
Shorter race formats (5K–10K) where fuelling isn't typically required
Runners who need the highest possible carbohydrate dose per gel (consider Gel 160 instead)

Training With Maurten Gel 100: Building Your Protocol

The most important practice with any gel is using it consistently in training before deploying it on race day. Here's a structured approach to building your Maurten Gel 100 protocol: Weeks 1–4 of training block: Take one Gel 100 at the 45-minute mark of every long run. Focus on confirming GI tolerance, getting comfortable with the texture, and establishing the consumption habit. Note your stomach response at various effort levels. Weeks 5–8: Add a second Gel 100 at 75 minutes. Experiment with taking the gel without stopping — practice opening the packet, squeezing the contents, and disposing of the packet without breaking stride. Weeks 9–12: Build to your target race-day intake rate. If your race goal requires one gel every 25 minutes (60g/hour from Gel 100), practice this frequency on your longest runs. Your gut should be adapted to the product and intake rate before your key race. Race simulation sessions (final 3–4 weeks): Use your exact race nutrition plan — product, dose, and timing — on your most important long run or race simulation. This is your final gut check before committing to the plan on race day. This progressive approach eliminates race-day nutrition surprises, which are among the most common causes of preventable marathon disasters for otherwise well-prepared runners.

Final Summary: Who Should Buy Maurten Gel 100

Strongest candidates:

Runners with documented GI issues with conventional gels
Marathon runners who've experienced mid-race stomach problems in previous events
Australian runners racing in summer heat where gut stress is compounded by thermoregulatory demands
Ultra runners who need flavour-neutral fuel sustainable across 4–24+ hour efforts
Athletes competing under anti-doping testing who need a well-credentialed product (Maurten has no banned substance concerns)

Consider alternatives:

Runners with excellent GI tolerance who've never had issues — SiS Beta Fuel delivers more carbohydrate per gel at lower cost
Training runs where premium performance investment isn't required — GU or Honey Stinger at half the price covers easy and moderate sessions adequately
Runners who absolutely need flavoured gels to maintain intake compliance — Maurten's neutral profile doesn't suit everyone

The Maurten Gel 100 is the most GI-protective, palatably neutral, and scientifically credible running gel available in Australia in 2026. For the runners who need it most, the investment is entirely justified. Final Rating: 9/10 Available at maurten.com/en-AU and iHerb AU. Prices approximate AUD as of 2026.
