As it gets hotter and more humid, the next few product reviews are geared towards hydration and fueling. Many people are familiar with an energy gel. There are plenty of brands out there, but GU was the first. Innovation is all we know. GU created the first energy gel over 20 years ago. It also has the widest variety.
In short, energy gels replenish your depleted carbohydrate stores when running—any endurance athlete from runners to swimmers or cycling benefits from taking fueling during training and racing.
Here is the Quick: “Why You Should Take Fuel While Running”
When you exercise, your body uses two forms of fuel to feed your muscles: fat and carbohydrates. Carbohydrates are the primary fuel source.
Your body can only store so many carbohydrates into your muscles. The stored carbohydrates are also known as “glycogen.” For most of us, the stored energy lasts about 90 minutes of running.
Fuel gives you a spike in energy and is absorbed into both the muscles and organs. This is where gels or any fuel comes into handy. Most gels contain about 25g of carbohydrates which is suitable for about 45 minutes of running.
This is all relative, and it’s crucial to figure out what works for you. It’s not the same for everyone. Many energy gels, including both GU Energy Gels and GU Roctane, contain other nutrients to help such as electrolytes or caffeine.
The bottom line is you should experiment for your own needs and what works for you. Runners need fuel after about 90 minutes to run their best. You can run longer than 90 minutes without fuel, but you won’t run your best. The longer the distance, the more energy you’ll need.
When Should you Take Fuel and Energy Gels During Long Runs?
The perfect time to take energy gels depends on you and your body. While I’m saying energy gels, it can be substituted for whichever works the best for you, whether you like liquid fuel, gel, block, or even a tab.
Every runner absorbs and processes carbohydrates differently. Some runners can feel the gel within a few minutes of taking it; others can take up to 15 minutes. It will take time and experimentation to figure out when to take gels.
Once you take an energy gel, your body diverts blood away from your stomach and towards your muscles. Sometimes your stomach might shut down completely, which can lead to cramps of bathroom stops. This is why you should take an energy gel with water.
How Often Should You Use Energy Gels?
Since blood is now diverted away from your muscles, it’s important not to overwork the stomach and take too many gels. Many runners take every 6-7 miles or ever 45 minutes. This keeps you from taking too much sugar or even too much caffeine.
A Few Things to Note about Energy Gels:
- Always take an energy gel before you think you need it: When you need a gel, the damage is done, and your glycogen stores are already too low.
- Take with Water: Taking an energy gel and a sugary drink often overwork the system.
Last, but Not Least:
Nothing new on race day, make sure you try your energy gels before you race with them. You don’t need to have stomach issues midway through a race because of a new energy gel.
