Energy Gels: How They Can Help You Fuel a Long Workout

If you are a long-distance runner, cyclist or any kind of endurance athlete, you may heard about energy gels or considered adding them to your nutrition strategy. What are these products and what’s the best way to use them? We talked to Cleveland Clinic dietitian Katherine Patton, MEd, RD, CSSD, LD to find out.

Q: What are energy gels?

A: Energy gels are carbohydrate-rich gels that provide energy for exercise. They are for use by adults and are made from a blend of sugars, most often maltodextrin and fructose.

Most energy gels come in 1-ounce or 1.5-ounce packets, which makes them convenient to consume during a long-distance event. Most energy gels have no fat, fiber or protein, so your body digests them quickly.

Q: Why use an energy gel?

A: Runners, swimmers, cyclists or anyone who exercises for more than 60 minutes needs to adequately fuel their body for the best workout. This is because while you exercise, your body draws on carbohydrates stored in your muscles. However, the available amount is limited.

Research shows consuming carbohydrates during exercise that lasts longer than an hour improves metabolic response and athletic performance and prevents glycogen depletion.

The American College of Sports Medicine recommends consuming 30 grams to 60 grams of carbohydrates per hour of exercise. Most energy gels pack 23 grams to 27 grams of carbohydrates while an 8-ounce sports drink provides 14 grams of carbohydrates.

Energy gels also are simple to consume, are not filling and an easily digestible source of carbohydrates that can help maintain energy and prevent fatigue during intense or prolonged periods of exercise.

Q: What precautions do I need to take with energy gels?

A: Energy gels contain a concentrated amount of sugar, so taking them too quickly could cause an upset stomach. To prevent this, wash down your energy gel with sips of water.

Though energy gels provide needed fuel, remember that what works for one athlete might not work for another. Each runner absorbs and processes carbohydrates at a different rate. One person might feel the effect within three minutes while others might take up to 15 minutes.

Also, keep in mind that if you are an endurance or an athlete training for competition, you need to devise a fueling strategy and incorporate it into your training regimen.

So eat gels while you are training, and consume them at intervals similar to your plans for race time.  Your body will learn to keep the digestive track active while you are running and so you will digest the gel more readily.

Plan a fueling strategy and practice it during long training sessions to determine what works best for you. Good training, proper fueling and adequate hydration provide the foundation for achieving your personal best.
