By Lauren HollandEnergy chews vs gels for running is a choice most distance runners face sooner or later, and the answer depends mainly on how your stomach handles fuel, how much carbohydrate you need per hour, and whether you prefer to chew or squeeze. Gels are the better pick for runners who want fast, portable carbs with minimal chewing and who already tolerate them well. Chews suit runners who find thick gel hard to swallow, want to spread intake out in smaller bites, or simply prefer something closer to real food. Both deliver the same core fuel, so the decision comes down to texture, packaging and practical habits.
Comparison at a Glance
| Criterion | Energy Gels | Energy Chews |
|---|---|---|
| Typical form | Thick, sticky liquid in a single-serve packet | Soft, gummy-style pieces in a pouch or box |
| Carbohydrate per serving | Commonly around 20 to 25 g in one packet | Commonly around 10 to 25 g per serving, depending on the product |
| Speed of intake | Fast; usually one squeeze with water | Slower; chewed over several minutes |
| Ease of carrying | Compact, but empty packets need disposal | Compact pouch; easy to split across pockets |
| Ability to dose in small amounts | Limited; one packet is one unit | Easy; take one or two pieces at a time |
| Stomach comfort at high intensity | Can be harsh for some runners, especially with little water | Often gentler for runners who react to thick gels |
| Caffeine options | Widely available | Available, though less common in some lines |
| Best for | Race pace efforts, quick fueling, runners who already use gels | Runners who need smaller, steady doses or dislike gel texture |
Carbohydrate Delivery and Fueling Targets
For efforts lasting longer than about 60 to 90 minutes, most sports nutrition guidance suggests consuming roughly 30 to 60 grams of carbohydrate per hour, with higher intakes (up to around 90 grams per hour) used by some runners who have trained their gut to tolerate it. Both gels and chews can meet these numbers, but they do it differently.
A typical gel packet delivers about 20 to 25 grams of carbohydrate in a single unit, so one packet every 40 to 45 minutes covers the lower end of the range. Chews vary more by brand. Some provide around 10 grams per piece and others around 25 grams per serving, so you need to read the label to know how many pieces make up one serving. Chews let you approach your target in smaller increments, which can be useful if you want to avoid large carbohydrate spikes or if you are trying to hit a number like 40 grams per hour without overshooting.
Winner for carbohydrate delivery: Gels for simplicity and a known dose per unit. Chews win if you prefer finer control over intake. Check the label on whichever product you buy, because serving sizes differ.
Speed and Convenience During a Run
Gels are hard to beat when you need to take fuel quickly. You tear the top, squeeze the contents, and typically finish in under a minute with a small sip of water. This works well on a crowded course, on a hill when your breathing is ragged, or in the middle of a race where you do not want to slow down much.
Chews take longer to eat. You need to chew each piece, and if you are running hard, chewing while breathing heavily can feel awkward. Many runners handle this by taking a few pieces at a time during an easier stretch of a long run or at a water station. Chews also make it easier to avoid overeating in one go, since you naturally pace yourself through the pouch.
Winner for speed: Gels. Chews are better when you have time to eat calmly, such as during a slower long run or a training session with planned breaks.
Stomach Comfort and Digestive Tolerance
Stomach comfort is often the deciding factor. Gels are concentrated and thick, and when taken without enough water they can sit heavily or cause nausea, particularly at race pace. Runners who experience this often report better results when they drink a few ounces of water with each gel and spread intake across the run rather than taking several packets back to back.
Chews are less concentrated per bite and dissolve more gradually as you chew and swallow. Many runners find them easier on the stomach, especially when intensity is high. That said, chews still contain fast-acting sugars, and some runners react to the sugar alcohols or gelling agents in certain formulas. Because individual tolerance varies so much, it is worth testing both during training rather than trying something new on race day.
Winner for stomach comfort: Chews for many runners, especially those who notice gut discomfort with thick gels. Gels remain a solid option if you have already trained with them and know how your body responds. Anyone with a history of digestive issues, diabetes or other medical conditions should consult a doctor or registered dietitian before changing fueling strategies.
Portability, Packaging and Waste
Gels pack flat and fit easily in a shorts pocket, a waistband or a hydration vest. The downside is that each packet leaves an empty foil wrapper that you need to carry until you find a bin, which can be inconvenient on rural routes. Some runners tuck the empties back into their pockets, which is a practical habit but one that many races discourage in favor of carrying them to the finish or to designated areas.
Chews come in pouches or small boxes that you can reseal, so you can carry a portion in your pocket and keep the rest protected from heat. Packaging is generally less wasteful per hour of fuel, and you do not have to manage multiple sticky wrappers. The trade-off is that a pouch can be bulkier than a few gel packets if you need many servings.
Winner for portability: Gels for compact single-serve packing. Winner for packaging: Chews for reduced waste and easier resealing.
Flavor, Texture and Personal Preference
Gels have a dense, syrupy texture that some runners find unpleasant, especially in hot weather when the consistency becomes runnier. Flavors range from fruit to coffee-style options, and some people find the sweetness cloying after the first hour. Chews offer a chewy, candy-like texture. Many runners find them more palatable over long periods, though some dislike the mouthfeel of gummy products while breathing hard.
Because taste fatigue is real during long races, having a choice of flavors helps. Many runners rotate between two or three flavors across a marathon or ultra so they are not relying on a single sweet profile for hours.
Winner for flavor variety: Tie. Both categories offer multiple flavors, and preference is highly individual.
Cost per Hour of Fueling
Cost comparisons depend heavily on brand, retailer and whether you buy in bulk. Gels are often sold in boxes of multiple packets and are a common choice in race expo packages. Chews are often sold in larger pouches. When comparing, calculate the cost per 40 to 60 grams of carbohydrate rather than per package, since that gives the most accurate picture of value. Budget-friendly store brands can offer good value, while premium options may bring extra features like added electrolytes or caffeine. Check current prices directly before deciding, since they change often.
Winner for value: Depends on the brand you choose. Compare cost per gram of carbohydrate across products you are considering.
Electrolytes, Caffeine and Added Features
Many gels and chews are available with added sodium, potassium or caffeine. Caffeine can improve perceived effort for some runners, but it is also a stimulant that can cause jitters, sleep disruption or gut upset. Manufacturers typically list the caffeine content on the label, and it is wise to test caffeinated versions in training. Electrolyte content matters more in hot conditions or on very long efforts, where sweat losses are higher. Runners who sweat heavily often pair either format with a separate electrolyte drink or tablets.
Winner for added features: Tie. Both formats are available with electrolytes and caffeine, so choose based on your needs and check labels carefully.
Which Should You Choose?
- Choose gels if you race at a steady, hard pace and need quick fuel with minimal stopping.
- Choose gels if you have already trained with them and know they sit well with your stomach.
- Choose gels if you want a predictable 20 to 25 grams of carbohydrate per unit and simple dosing.
- Choose chews if thick gels cause nausea or stomach discomfort during hard efforts.
- Choose chews if you prefer smaller, spread-out doses rather than one large hit at a time.
- Choose chews if you want less packaging waste and easier resealing during long training runs.
- Consider using both if you want gels for race pace and chews for easy long runs, which also helps you test which you tolerate best.
Products to Consider
Both categories have well-known options. For gels, you might look at the GU Energy Gel, which is widely used by runners, or the Maurten Gel 100, a popular choice among competitive athletes. For chews, the Clif Bloks and Honey Stinger Chews are commonly found in running stores and are widely available online.

FAQ
Are energy chews or gels better for marathons?
Gels are often preferred for marathon race pace because they are fast to consume and deliver a predictable amount of carbohydrate. Chews work well for many runners too, especially those who experience stomach discomfort with gels. The best choice is the one you have tested during long training runs.
How many grams of carbohydrate should I take per hour while running?
Many sports nutrition guidelines suggest 30 to 60 grams per hour for efforts longer than about 60 to 90 minutes, and some trained runners tolerate up to around 90 grams per hour. Start at the lower end and increase gradually during training. Consult a registered dietitian or doctor if you have a medical condition that affects blood sugar.
Do gels need to be taken with water?
Most gel manufacturers recommend taking them with water to help digestion and absorption. Many runners drink a few ounces with each gel. Without enough fluid, some people experience stomach upset, particularly at high intensity. For another angle, check out Maple Syrup vs Energy Gels (2026): Which Is Better for Marathon Fueling?.
Can I use chews and gels together in the same race?
Yes, many runners combine them to reduce flavor fatigue and spread out their intake. Mixing formats can also help you find the combination your stomach tolerates best. Test any combination during training before race day.
Do energy chews or gels contain caffeine?
Both formats are available with caffeine, and labels list the amount per serving. Caffeine can help some runners but may cause side effects in others. If you are sensitive to stimulants or have a heart condition, check with a doctor before using caffeinated fuel.
Conclusion
Energy chews vs gels for running does not have a single universal winner. Gels are fast, compact and predictable, which makes them a strong choice for race pace and for runners who already tolerate them well. Chews are gentler for many stomachs, allow smaller and more flexible doses, and produce less waste per hour of fuel. Test both during your long runs, pay attention to how your stomach responds at race intensity, and build your race-day plan around the format that keeps you moving comfortably from start to finish.
