The 10 Best Gels for Running a Marathon – Three Types to Consider

Looking for the Best gels for running?

Since the first marathon was held in ancient Greece, people have worked on ways to provide their bodies with a little bit of extra energy. Since then, the technology behind exercise supplements evolved, and now, we have the best gels for running a marathon.

Running gels are a vital part of the long-distance runner’s life. In this article, we’re going to explore how they work, how many different types of gels are out there, and which type is going to suit you best. You’re also going to find a list of top ten energy gels that you can get on Amazon right from the comfort of your own home.

Why Gels Are Important During Long Runs

To understand why the best gels for running a marathon are synonymous with a good marathon run, we have to go over what energy gels are. An energy gel is a sports supplement that provides your body with the necessary carbohydrates used to feed your muscles in the long run – quite literally.

You might ask yourself why you need a gel to provide you with carbohydrates if your body already has carbohydrates stored in muscles, known as glycogen. Our muscles have a limited amount of glycogen, that could last us about half a marathon.

That’s why you need an energy gel. The gel replenishes your glycogen storages and allows you to run for longer lengths. It’s first absorbed into your bloodstream, then absorbed by active muscles and organs. Professional runners prefer using energy gels as opposed to other energy replenishing products.

It’s essential to take the gel before you develop a need for it, as the time before the first effect kicks in differs from individual to individual. Someone will feel that the gel hits within 3 minutes, yet it can take up to 15 minutes.
You must experiment a bit with the best gels for running a marathon. You should practice with an energy gel to get used to it and to find out which one best fits your needs. Different types of gels serve different purposes, all of which will be discussed below.

Types of Gels

There are three types of best gels for running a marathon. Those three differ in features when compared to one another. Yet, all of them are used for the same purpose. Learning about the effects all special gels have on your system will help you choose the best option.

Isotonic Gels

Isotonic gels have a similar concentration of salts, water, and carbohydrate as our blood. Isotonic means the source of carbohydrates, and its purpose is to refill your organism with carbs that you lost while sweating.

Isotonic gels require more energy to get across the gut wall, so the electrolyte and energy release is slowed down. Some of these might make you a little sick in your stomach. If this is the case, try diluting the supplement in water. Mixing with water is often not recommended because it lowers down the level of energy you are going to get, but it could be of help to those with a quaky stomach.

Some of us went through the trauma of consuming supplements or healthy drinks that taste awful. With running gels, it’s usually not much different. They are available in many different flavors, so it makes swallowing them much, much more manageable.

Hypotonic Gels

Hypotonic gels have a lower concentration of fluid sugar and salt than our blood. They are best used for rehydration because they have a smaller percentage of carbohydrates and salts in the blood. That makes it easier for the supplement to enter your bloodstream.

Hypotonics’ primary focus is rehydration, so if you are going for a long run, mix it with other energetic supplements. They are far more preferable for the short workout sessions. You will also gather more strength because they enter the bloodstream and your system faster, giving a slight boost to push your limits.

Hypotonic products, and Isotonic or Hypertonic, vary depending on the brand of your choice.

Hypertonic Gels

They are best used for recovering strength because they boost your body with extra doses of carbohydrates, sugars, and salts. As you probably concluded, Hypertonics have more fluid, sugars, and salts than your organism.

Sometimes they contain added protein. That is superb because proteins are some of the best supplements around. They’re the building blocks of muscles, and muscles are essential when it comes to running and endurance – making them the biggest energy boosters of the mentioned groups.

Factors to Consider When Picking a Running Gel

When you’re picking the best gels for running a marathon on the market, you want to get those who will fulfill some essential requirements. A good energy gel should have:

Fast Absorption

When you’re running a marathon, you want the effect to be as instant as possible. That is why the best energy gels on the market come with an unparalleled absorption rate, which will keep you running like a well-oiled machine.

Filling you up with energy during your run, the best energy gels on the market don’t cease to amaze. Since absorption rates and energy input are two of the essential things in an energy gel, the technology behind creating such a supplement is continuously improving – and absorption rates are only going up.


Let’s face it, that gorgeous chocolate-flavored protein powder tastes nothing like the real thing, and a bad taste can be a real put off.

But, technology has evolved since the olden days, and now, these best energy gels taste fantastic. When you’re picking out an excellent energy gel option, you want it to feel like something you love. Just don’t experiment too much – since exotic flavors of supplements taste nothing like the real thing.


Carbs, proteins, and fats might be the most popular macronutrients around, but they all have their subcategories. The essential types of carbs are fibers. Fibers are crucial if you’re looking for longevity, improving your stomach health, and long-lasting effects.

The best energy gel on the market should be jam-packed with different fibers, which will ensure that your energizing effect lasts for the entire duration of the marathon. Gold medal, here we come.


There has been a lot of talking lately about the way we consume our daily nutrients. One of the most shocking things around is that most of our food comes jam-packed with artificial nutrients, empty calories, and more artificial than organic matters.

That is why the best supplements on the market are entirely organic. While organic products might cost a little more when compared to the artificial stuff, they’re miles ahead of the competition when it comes to health benefits – which is essential in energy gels for runners.
