Best Energy Chews for a Half Marathon

A half marathon demands respect. It is far enough to drain your energy stores if you get it wrong, yet fast enough that every fuelling decision can influence your performance.

For most runners, you are looking at 90 minutes to 2 hours plus of sustained effort. That means topping up carbohydrates consistently to avoid the dreaded late race fade. Energy chews are a brilliant option here. They are easy to carry, simple to portion, and often easier on the stomach than large gels taken in one go.

How to Use Energy Chews in a Half Marathon

For most runners:

• Start fuelling around 20 to 30 minutes into the race
• Take small amounts every 15 to 20 minutes
• Pair with water to aid absorption
• Adjust intake based on pace and temperature

If you are aiming for a sub 1:30 half, your carbohydrate needs will be higher per hour than someone running 2:10. This is where our Nutrition Calculator becomes invaluable. It will give you a personalised carb per hour target and help you build a race plan you can add straight to your basket.

What to Look for in Energy Chews

Not all energy chews are created equal. When you are choosing the right option for a half marathon, it is worth looking beyond flavour and thinking about how they fit into your overall fuelling plan.

Consider the type of carbohydrates used. Many of the better options use a mix of glucose and fructose, which can improve absorption and help you tolerate higher carb intakes without upsetting your stomach.

Texture matters too. Some chews are firmer and require more chewing, while others are softer and easier to eat at race effort. If you struggle to chew when breathing hard, opt for a softer consistency and always practise in training.

Here are some great options available at XMiles:

226ERS Vegan Gummy Bar

A strong choice for half marathon runners who want steady, manageable carbohydrate intake, each bar delivers a balanced carb profile in a firm but chewable texture that holds up well in pockets or race belts.

Because it comes as a bar format, you can break it into smaller pieces and fuel consistently every 15 to 20 minutes rather than taking a full hit at once.

Luchos Guava Energy Blocks

Made from natural guava paste, these traditional Colombian energy blocks provide simple carbohydrates in a compact, real-food format. They are denser than most modern chews, which makes them practical for runners who prefer something less processed and sticky.

The flavour is naturally sweet without being overpowering, and they can be portioned easily across the race, making them great for runners who struggle with overly synthetic textures.

Precision Fuel PF 30 Energy Chews

Built around simplicity and accuracy, each pack provides 30g of carbohydrate, making it easy to track intake during a half marathon. Lightweight, easy to consume, and kind on the stomach, these chews are great on the go.

They use a dual-source carb blend to support efficient absorption and are designed to be easy to chew at race intensity. Ideal if you like a structured, numbers-based fuelling approach.

TORQ Energy Jellies

Designed specifically for endurance performance, these jellies deliver a blend of glucose and fructose to support efficient carbohydrate uptake. Each pack provides around 30g of carbohydrate and includes electrolytes, helping to support both energy and hydration needs.

They are a particularly good option if you already use TORQ gels or drinks and want to stay within one fuelling system.

FAQs

How many energy chews should I take in a half marathon?

It depends on the carb content per pack and your target per hour. Most runners will take 1 to 2 packs across the race, spaced out in smaller portions.

Are energy chews better than gels for a half marathon?

Not necessarily better, just different. Chews allow more control and can feel gentler on the stomach. Gels are quicker to consume. It comes down to personal preference and tolerance.

Should I take caffeine in a half marathon?

Caffeine can improve perceived effort and focus, especially in the final third of the race. If you choose a caffeinated chew, trial it in training first to check tolerance.

Summary

Energy chews are one of the most practical fuelling options for a half marathon. They allow you to control portion size, manage sweetness, and avoid the all at once hit that some gels can bring.

Dial in your carbohydrate target, practise in training, and go into race day with a clear fuelling plan.
