If you are a runner, the chances are you have bought and consumed dozens of energy gels. The market place for energy gels is huge – and still growing. 

Just take a look at the shelves of any sports shop or, indeed, larger supermarkets to see the many different brands and types of energy gels. But they are not cheap, are they? 

It can also be argued that the use of many one-shot energy gels is wasteful and potentially unfriendly to the environment because they are usually packaged in some kind of throw-away plastic or foil container or wrapper. And don’t get us started on all the discarded energy gel wrappers you see littering the streets and countryside.

So what is the alternative? How about you make your own energy gels?

It’s actually not so difficult to make your own energy gels, because many ingredients found in shop-bought gels are simple and easily available in supermarkets. 

First, let's take a closer look at energy gels for runners.

Why use energy gels?

Most energy gels are made of a water, flavouring – often fruit juice – and some form of quick-digesting carbohydrate. This could be in the form of maltodextrin, sucrose, fructose, or glucose. Some energy gels also include a list of additives that might not be so attractive the you stop to think about them. 

Making your own energy gels has a few advantages. Running coach and sports nutrition specialist, Claire Bartholic, of the The Planted Runner, says: “While commercial gels are convenient, making my own gels is a lot less expensive and I can control the ingredients.  

“I also get a lot of requests from the athletes I work with for whole food gels, so I have come up with my own.”

Ingredients for homemade energy gels

It's recommended you'll nee a variety of carb sources is the key to achieving higher levels of absorption. This is because the different sources are also metabolised at different rates. Gels may also include caffeine, which some studies shows can improve exercise performance

Many athletes, especially long-distance runners and cyclists, use gels them to improve performance and maintain blood sugar levels.

so, to make your own energy gels, you’ll need a mix of quick-digesting carbs. Let’s take a look at different sugar and their sources. (Information from Sugar Nutrition.)


Sucrose is a naturally occurring sugar. It is derived from sugar cane and sugar beets. It’s also found in fruit (apricots, oranges, pineapples, and peaches, for example, are high in sucrose) veg (such as beetroot and carrots), and nuts. Table sugar is the easiest source.


Fructose is also a form of sugar and a basic component in table sugar (sucrose). On its own, it’s found naturally in honey, fruits, fruit juices and dried fruits. You can find some of the fruits with the highest values of fructose.

Vegetables have fructose, too, for example, artichokes, asparagus, broccoli, leeks, mushrooms, onions, red pepper and tomatoes.

Glucose is another simple sugar, and is found in a range of natural foods, as well as manufactured products.

As a source of glucose in your homemade energy gels, you could use honey, golden syrup, dried fruits like dates, currants and figs, and some juices. 


Maltodextrin isn't a sugar, although it behaves in a similar way when it comes to impacting blood sugar levels. Manufacturers of Maltodextrin extract it from starchy foods such as potato, corn and wheat. It often takes the form of a powder and is sold by a range of suppliers. 

Maltodextrin is easily digestible, being absorbed as rapidly as glucose, and may be either moderately sweet or almost flavorless.

How to carry your homemade energy gels

Once you have made your own energy gels, you’ll need to find a way to transport them. Energy gels can be sloppy or sticky, or both, and that means you need a secure and watertight container. 

Ideas for containers for homemade energy gels include reusable and squeezable plastic food pouches. For example, soft flasks, normally used for carrying water with you, could be filled with gels that are quite fluid.

Also, try baby food bags, which usually contain fruit purée.  These can be found in supermarkets. Empty the puree (keeping it in a Tupperware or similar for future use), wash and reuse.

Silicone travel bottles also make a good container for energy gels. 

If the gels are more solid you could simply use sandwich bags or baking parchment paper.
