Best Energy Chews for Marathon Running 2026

If you’ve ever tried choking down a gel at mile 18 while gasping for air, you know the struggle. Energy chews are the alternative that more and more marathon runners are turning to — they’re easier to chew, easier to portion, and frankly just more pleasant to eat when you’re deep into a race.

I’ve tested dozens of chews over training cycles and race days. Here’s what actually works in 2026, who each option is best for, and how to nail your fueling strategy.

Best For Each Runner

Best for easy eating on the run: Clif Bloks. The sleeve design lets you squeeze blocks out one-handed without breaking stride. The soft texture means minimal chewing — critical when your breathing is heavy.

Best for sensitive stomachs: Skratch Sport Energy Chews. Made with real fruit and minimal ingredients. No artificial colors, no mystery additives. If other fuel gives you GI distress, start here.

Best on a budget: GU Energy Chews. At $2 per pack, these are the most affordable option without sacrificing quality. You’ll go through a lot of fuel during a training cycle — the savings add up.

Best premium option: Maurten Solid. The rice crisp texture is unlike anything else on this list. Maurten’s hydrogel technology means excellent absorption, and the brand has become the go-to for elite runners. You pay more, but you’re getting cutting-edge sports nutrition.

Chews vs. Gels: When Each Is Better

This isn’t an either/or situation. Most experienced marathoners use both during a race. Here’s when each makes more sense:

Choose chews when:

• You dislike the slimy texture of gels
• You want to portion your carbs more gradually (eat one chew at a time over several minutes)
• You’re running at a comfortable pace where chewing isn’t difficult
• You have a sensitive stomach — chewing starts digestion in the mouth
• You prefer something that actually tastes like food

Choose gels when:

• You’re running at threshold pace and can’t chew easily
• You need fast absorption in the final miles
• You want the simplest possible fueling (tear, squeeze, done)
• You’re at an aid station and can wash it down immediately

Many runners use chews in the first half of a marathon when effort is more controlled, then switch to gels in the back half when chewing becomes harder. Check out our full gel breakdown if you want to combine both strategies.

How Many Carbs Per Hour for a Marathon

The research is clear: you need 60-90g of carbs per hour during a marathon. That’s significantly more than most runners actually take in.

Here’s what that looks like with chews:

• 60g/hour (minimum effective): About 2.5 servings of most chews per hour
• 75g/hour (sweet spot for most): About 3 servings per hour
• 90g/hour (aggressive, for experienced fuelers): 3.5-4 servings per hour

For a 4-hour marathon, that’s roughly 240-360g of total carbs during the race. Yes, that’s a lot of chews. This is why many runners mix chews with gels and electrolyte drinks that contain carbs.

Important: Your gut needs to be trained to handle this volume. You can’t just show up on race day taking in 90g/hour if you’ve never practiced it. More on that below.

Timing Your Fueling

Getting the timing right matters as much as the total amount. Here’s a practical fueling schedule for a marathon using chews:

Miles 1-3: Nothing. You’re running on breakfast and glycogen stores.

Mile 4-5: First serving of chews. Start early before you feel like you need it. By the time you feel depleted, it’s too late to catch up.

Every 3-4 miles after that: Another serving. Set a reminder on your watch if you tend to forget.

Miles 20+: Switch to gels if chewing becomes difficult. This is where the race gets hard and your jaw might not want to cooperate.

With every serving: Take water at the next aid station. Chews need fluid to digest properly. Don’t skip this step — dry chews sitting in your stomach will cause problems.

A few things that mess people up:

• Waiting too long to start fueling (the “I feel fine” trap)
• Taking too much at once instead of spreading it out
• Forgetting to drink water with their chews
• Changing their plan mid-race because of nerves

Practice Your Nutrition Plan

I cannot stress this enough: practice your exact race-day nutrition in training. Your marathon fueling plan should be boring and predictable on race day because you’ve done it twenty times before.

Here’s how to build up:

1. Start in easy long runs. Pick one brand and use it every weekend long run for a month.
2. Increase the amount gradually. Start with 40g/hour, then 50, then 60, building toward your race-day target.
3. Simulate race conditions. Practice at marathon pace, not just easy jog pace. Your gut behaves differently at higher intensities.
4. Test in heat. If your race might be warm, train with your fuel in warm conditions. Heat slows digestion.
5. Lock it in 4 weeks out. No new foods, no new brands, no experiments in the final month before your race.

If a chew doesn’t sit well during training, switch brands early. You have time. Don’t be loyal to a brand — be loyal to what your stomach actually tolerates.

And while you’re dialing in nutrition, make sure your shoe setup is equally locked in. Race day should have zero surprises.

FAQ

How many energy chews should I eat during a marathon? Most runners need 8-12 servings across the entire race to hit 60-90g of carbs per hour. That means carrying 3-4 packs, depending on the brand. Use a running belt or shorts with pockets to carry them.

Can I use energy chews for half marathons too? Yes, but you’ll need less. For a half marathon, 1-2 packs is usually sufficient. If you’re finishing under 90 minutes, you might not need any at all — your glycogen stores can cover that distance. Over 90 minutes, fuel up.

Do energy chews expire? They have a shelf life of about 12-18 months. Check the date on the package. Expired chews won’t make you sick, but the texture gets weird and the carbs may not absorb as effectively.

Should I choose caffeinated chews? Caffeine can boost performance in the later miles, but it can also cause GI issues if you’re not used to it. Save caffeinated chews for miles 16+ when you need a mental and physical lift. Never try caffeinated options for the first time on race day.

Are energy chews better than real food like dates or gummy bears? Energy chews are engineered for fast absorption and easy portioning. Real food works for some runners — dates and gummy bears have their fans — but they don’t have the electrolytes, precise carb counts, or easy packaging of purpose-built chews. For racing, I’d stick with sports-specific products. For easy training runs, real food is fine.

The Bottom Line

Energy chews are one of the most runner-friendly ways to fuel a marathon. They’re portable, taste decent, and give you control over your carb intake in a way that gels don’t always allow.

Pick one from this list, test it in training, and build your fueling plan around what your body actually tolerates. The “best” chew is whichever one you can eat at mile 22 without wanting to throw up. That’s the bar — and it’s a real one.
