For anyone venturing into long-distance running, proper nutrition for endurance athletes is essential to reaching big goals. Whether you’re training for a half marathon, marathon or ultra marathon, having a solid nutrition strategy in place well before race day can make all the difference. One of the easiest ways to fuel your runs is with energy gels.
When running, your body uses two sources of fuel – fats and carbohydrates. Fats are more readily available in the body, but they take longer to break down into usable energy. Carbohydrates break down quickly, making them the primary fuel source your body relies on during a run. The problem is your body can only store a limited amount of carbohydrates at a time. This is where running gels, also known as energy gels, come into play. Packed with carbs and available in portable packets around 1 to 1.5 ounces, running gels are ideal for athletes looking to bring fuel with them on long training days.
There is no “perfect time” to take an energy gel, as every runner absorbs and processes carbohydrates at a different rate. According to Sanford Health’s carbohydrate guidance for runners, runners should aim to consume 40-60 grams of carbohydrates per hour after the first hour of running, then about every 45 minutes thereafter. It is important to take the gel before you “hit the wall” to help avoid lactic acid build-up and fatigue.
Knowing when to fuel is only part of the equation—the energy gel you choose can also affect how comfortable your fueling feels during a run. Running gels vary in carbohydrate content, texture, flavor, caffeine and ingredients, so the best option will depend on your distance, intensity, dietary needs and stomach tolerance. Below, we break down our top running-gel picks and explain which type of runner each one may suit best.
For 30 years, GU has developed some of the most tried and true energy gels on the market. The company offers three different types—the original, Roctane, and liquid—that come in more than 30 different flavors from salted caramel to raspberry lemonade. Depending on your texture preference, you might opt for a smooth gel or go for the fast-absorbing liquid.
For long-duration and high-intensity exercise, GU offers the Roctane energy gel, which carries more electrolytes and amino acids than the original. Each energy gel holds 21-23 grams of carbohydrates per packet. If you’re unsure which to pick for your next training session, check out GU’s handy suggested use guide.

Over the last several years, Maurten has quickly become a favorite source of fuel for elite athletes, including marathon world record-holder Eliud Kipchoge. What sets Maurten’s energy gel apart is the product’s hydrogel technology, which has proven to be a gamechanger for runners who are prone to GI issues.
So, what is hydrogel technology? Alginate (a fiber extracted from seaweed) and pectin (found in fruits and vegetables) create a capsule that contains salt, glucose and fructose. Thanks to that encapsulation, the body can absorb more carbohydrate with relative ease through the digestive tract
Maurten’s energy gels come in two options—the GEL 100 and the GEL 100 CAF 100 (which contains 100 mg of caffeine)—that both deliver 25 grams of carbohydrates.
Best for: As many pros can attest, Maurten energy gels are a great choice for those who experience GI issues while on the run.

Made with zero sugar and no caffeine, UCAN’s energy gels boast a formula that helps endurance athletes release steady energy for up to 75 minutes at a time.
