Buying Guide
Carbohydrate Content and Concentration
Most gels provide roughly 20 to 25 grams of carbohydrate per packet, but concentration and formula type vary. Check the nutrition label for total carbohydrate per serving and whether the gel uses a single sugar or a blend. Higher-carbohydrate formulas suit longer efforts, while lighter gels may be easier on the stomach for shorter sessions.
Good picks for this: GU Energy Roctane Ultra Endurance Energy Gel, GU Energy Original Energy Gels
Caffeine Content
Caffeine can help late in a race, but it is not right for every runner or every training day. Decide whether you want caffeine before you buy, and read the label for the amount per packet. If you plan to use caffeine on race day, rehearse it in training first.
Good picks for this: Honey Stinger Organic Strawberry Kiwi Energy Gel, Honey Stinger Gold Energy Gel
Dietary Restrictions
Check labels for gluten, caffeine and plant-based status if these matter to you. Many gels are gluten-free, but cross-contamination policies vary, so runners with celiac disease should confirm with the manufacturer. Consult a healthcare professional for medical dietary guidance.
Good picks for this: Honey Stinger Organic Fruit Smoothie Energy Gel, Real Food Huma Chia Energy Gel
Texture and Ease of Swallowing
Gels range from thin and runny to thick and paste-like. Thicker gels can require more water to swallow, which matters on hot days or in crowded races. Practice with the texture you plan to use on race day so you know how it sits.
Good picks for this: Honey Stinger Gold Energy Gel, Real Food Huma Chia Energy Gel
Flavor Variety
Flavor fatigue is a real problem over a 20-mile or longer run. Multipacks with mixed flavors let you rotate options and find what your palate tolerates. Test flavors on training runs rather than trying something new on race morning.
Good picks for this: GU Energy Original Energy Gels, Real Food Huma Chia Energy Gel
Pack Size and Training Volume
Estimate how many gels you need per week and per race. Larger counts usually reduce the cost per packet, while smaller boxes are easier to carry in a running belt or pocket. Match the pack to your training plan rather than buying for a single race.
Good picks for this: GU Energy Original Energy Gels, GU Energy Roctane Ultra Endurance Energy Gel
Packaging and Portability
Single-serving packets are easiest to carry and open one-handed. Look for tear-open tops that work with gloves or sweaty hands. Packets should fit a standard running belt or shorts pocket without leaking.

FAQ
How many energy gels should I take during a marathon?
Many marathon plans suggest roughly one gel every 30 to 45 minutes after the first hour, though individual needs vary with pace, body size and weather. Rehearse your schedule in training to confirm what your stomach tolerates.
Do I need to take water with energy gels?
Most gels are designed to be taken with water to help digestion and swallowing. Thicker gels generally need more water. Plan your water stops around your gel schedule.
Are caffeinated gels safe for everyone?
Caffeine affects people differently, and some runners should avoid it entirely. If you have a heart condition, anxiety, or take medication, consult a healthcare professional before using caffeinated gels.
Can I use energy gels on training runs?
Yes, and you should. Practicing with gels on long training runs helps you learn how your stomach responds and lets you refine timing before race day.
What is the difference between gels and chews?
Gels are concentrated liquid or paste packets that are typically taken with water, while chews are solid pieces that are chewed. Chews can be easier for runners who dislike the texture of gels, though they require more chewing time during a run.
How should I store energy gels?
Store gels at room temperature away from direct sunlight and extreme heat, which can change texture. Check expiration dates on the packaging and avoid leaving gels in a hot car.
Do energy gels expire?
Yes. Each gel carries a best-by date, and performance and texture can decline after that. Rotate your stock so older packets get used in training first.
Conclusion
For most marathoners, the strongest starting point is a concentrated, well-known formula such as the GU Energy Roctane Ultra Endurance Energy Gel. Runners who want a caffeine boost late in a race should consider the Honey Stinger Organic Strawberry Kiwi Energy Gel, while those with sensitive stomachs may prefer the Real Food Huma Chia Energy Gel. Gluten-free and caffeine-free runners have solid options in the Honey Stinger Organic Fruit Smoothie and Gold gels, and the GU Energy Original multipack suits high-volume training on a budget. Whichever you choose, rehearse your gel plan in training before race day.
