How to Choose the Right Energy Gels for Running

Runners with energy gels smile on their run.

Did you know the human body can only store 1,600 to 2,000 calories of glycogen, the energy your muscles use to power you forward?

That’s why it’s important to replace the energy stores you exert while running - especially when your mileage and time-on-feet exceed 90 minutes - and throwing back an energy gel is the most convenient way to do so.

With so many options to choose from, it can seem overwhelming to find the right gels for running. Read on to find out how gels work, when you should use them and how to choose the right gels for running.

How Energy Gels Work

When running, your body uses two sources of fuel – fats and carbohydrates. Fats are more readily available in the body, but they take longer to break down into usable energy. Carbohydrates break down quickly in the body, making this the primary fuel source your body relies on. The problem is your body can only store a limited amount of carbohydrates at a time. This is where energy gels come into play. Energy gels are quickly absorbed into the bloodstream, providing a spike in energy. Gels also contain other ingredients like electrolytes and even caffeine to further boost performance.


When to Use Energy Gels

There is no “perfect time” to take an energy gel as every runner absorbs and processes carbohydrates at a different rate. According to an article published by Sanford Health, runners should aim to take in 40-60 grams of carbohydrates per hour after the first hour of running and continue to consume that amount about every 45 minutes thereafter. It is important to take the gel before you “hit the wall” to help avoid lactic acid build-up and fatigue.


How to Choose an Energy Gel

With so many energy gels available, choosing the right one can seem daunting. We’ve broken down four of the most popular brands to help you decide which energy gel is right for you. Remember, it’s important to practice with gels prior to race day. This will help ensure your body can tolerate the gel while running and that you can tolerate the flavor.

No matter which gel you end up choosing, make sure to take them with water. Energy gels contain lots of sugar and sodium and without water, they take longer to digest. Read on to find out more about the most popular types of energy gels.

A common problem amongst runners, whether we like to talk about it or not, is fitting in those frantic bathroom breaks on the run.

Maurten uses only 6 ingredients in their energy gels. They don’t use any preservatives, artificial flavors or allergens. This is another reason why Maurten energy gels are easier on your stomach than other, traditional gels.
