How to Choose the Right Running Gel
Selecting the right energy gel involves understanding several key factors that impact your energy needs and race-day comfort. Your ideal gel depends on your individual pace, the duration of your run, and your dietary tolerances.
Consider the Carbohydrate Source
Energy gels typically use various types of carbohydrates, such as maltodextrin and fructose. For endurance efforts exceeding 60 grams of carbs per hour, a blend of different carb types is recommended to maximize absorption and minimize stomach issues. Maltodextrin offers a less-sweet, easy-to-digest option, while fructose can aid in higher hourly carb intake. Some natural gels rely on honey, maple syrup, or fruit purees for their energy source.
Evaluate Added Ingredients
Beyond carbs, many gels include performance-enhancing additions:
- Electrolytes: Sodium is the primary electrolyte lost in sweat and is crucial for maintaining fluid balance. Electrolyte-enhanced gels are especially important for heavy sweaters or in hot weather.
- Caffeine: Often added to boost mental alertness, improve concentration, and reduce the perception of effort. It's vital to test caffeinated gels during training, as they can cause stomach issues for some individuals.
- Amino Acids: Branched-Chain Amino Acids (BCAAs) may help reduce mental fatigue and muscle damage during long, intense efforts. GU Roctane is a well-known example of a gel with added BCAAs.
Find a Suitable Taste and Texture
Palate fatigue is a real issue during long events, making taste and texture a critical consideration. Gels range from thick and syrupy to thin and watery. Isotonic gels, like SiS GO, have a thinner consistency and are designed to be consumed without extra water. Others, like Maurten, use hydrogel technology to create a thicker, jelly-like texture that can reduce the risk of digestive issues.
Prioritize Digestibility
For many runners, stomach upset is a primary concern. The key is to find a gel that works for your unique digestive system. Brands like Huma use natural ingredients like chia seeds for a gentle, slower-release effect, though the chia texture isn't for everyone. Hydrogel technology, as used by Maurten, can also minimize stomach stress by encapsulating carbs. Always test gels in training before using them on race day to avoid unexpected gut distress.
Top Energy Gels for Runners
Maurten Gel 100
Praised by elite athletes like Eliud Kipchoge, Maurten's unflavored gel is known for its hydrogel technology, which allows for a high hourly carb uptake with minimal GI issues.
GU Roctane Energy Gels
Designed for high-intensity and long-duration exercise, GU Roctane packs more electrolytes and BCAAs than the original GU gels, helping to delay fatigue.
SiS GO Isotonic Energy Gel
The world's first isotonic gel, this product can be consumed without extra water, making it a convenient option for runners who want to minimize the fluids they carry.
Huma Chia Energy Gels
Made with real food ingredients like fruit puree and chia seeds, Huma offers a natural, stomach-friendly fuel source that provides a steady energy stream.
UCAN Edge
Using a slow-burning complex carbohydrate called LIVSTEADY, UCAN Edge provides consistent energy without the sugar spikes and crashes associated with some other gels.
Untapped Pure Maple Syrup Gels
A simple, all-natural option made from pure Vermont maple syrup, providing clean energy with natural electrolytes and minerals.

Best Practices for Using Gels
- Timing is key: Don't wait until you feel fatigued. Take your first gel 60-90 minutes into your run, and then every 30-45 minutes thereafter. Your body diverts blood from your stomach to your working muscles during intense exercise, which can slow digestion, so fueling proactively is crucial.
- Stay hydrated: Unless you're using an isotonic gel, it's vital to chase your gel with water. Water aids in digestion and absorption. Avoid taking gels with a sports drink, as it can lead to an overabundance of sugar and cause stomach issues.
- Train your gut: Practice with your chosen gels during training runs, especially your longer sessions. This allows your digestive system to adapt and ensures there are no surprises on race day.
- Start small: If you're new to gels, start by taking only half a packet to see how your stomach reacts before ingesting a full serving.
- Consider distance: For shorter events under an hour, gels are often unnecessary. For half marathons, you may need 2-4 gels, while marathoners might need 8-12 depending on pace and duration. For ultras, a mix of gels and other real food sources is often needed to combat flavor fatigue.
- Carry them wisely: Find a comfortable way to carry your gels, whether in a race belt, hydration vest, or shorts pockets. There are also reusable gel flasks for those who prefer to carry multiple servings.
Conclusion
Finding the right fuel can be a game-changer for your running performance, especially during endurance events. The best gels for runners depend heavily on individual needs, including desired carb intake, stomach sensitivity, and taste preferences. From cutting-edge hydrogels like Maurten to all-natural options like Huma, a wide range of products cater to different fueling strategies. The most important step is to experiment during training to find a gel and a fueling schedule that works for you, ensuring you cross the finish line feeling strong and energized.
