If you’re planning on running long distances, you need the best running gels you can find. Without fuel to power you through those long, hard miles, you won’t be able to perform at your best.
The energy that’s contained in running gels can make a big difference as to whether you finish your race with a bang or a whimper.
Quick Look: Our Top Picks
Why Do I Need Running Gels?
You never heard about the great runners of the 1970s taking energy gels when they ran marathons. Why should you? You’re at least as tough as they were, right?
Using energy gels has nothing to do with how tough you are. We use them to get the best performance we can. We know better now than we did in the 1970s about what happens to our bodies during long runs.
Here’s why energy gels can boost our performance during long runs. We all know that our bodies use both fat and carbohydrates to fuel our runs.
But fat breaks down so slowly that it can’t keep up with your needs when you’re running, especially if you’re running quickly. And our bodies can only store so much of glycogen produced after we eat carbohydrates.
You won’t nearly have enough stored to make it to the finish line of a marathon, or for some people, even a half marathon.
That’s why carbohydrates are so important during runs -- our bodies have used up the reserves they have in store. That means there’s not enough gas left in our tanks.
Most of all, you want fast-acting carbohydrates that will be readily accessible for your body to tap. That’s what energy gels can offer runners.
What’s in These Gels?
Most energy gels mainly contain sugars and maltodextrins. They don’t have fat, fiber or anything else that would slow down their digestion. They also usually contain sodium and potassium.
You can also find some with herbs like chamomile and ginger. Some gels also contain caffeine, and you’ll usually pay more for these gels.
Caffeine gives you an edge in a race, and it’s perfectly allowable for all runners to use, even in competition. But some runners don’t like the jittery feeling that caffeine can give them.
Other runners just don’t have the stomach for it. Caffeine is known to bother the stomachs of some athletes, causing nausea and even diarrhea -- just what you don’t want as you head into a race.
How Do I Use Running Gels?
The cardinal rule of using energy gels is this -- you must always drink water when you take them. Don’t use them with sports drinks, like Gatorade. That’s doubling up on the carbohydrates, which can cause more problems for you.
The other big rule is this -- never take an untried gel for the first time on race day. You could end up setting a record -- the fastest sprint to the porta potty. That’s because some gels create gastrointestinal distress for runners.
You should experiment weeks before your race with different gels to see which one gives you the best results without any unwanted side effects.
How Often Do I Need to Take Running Gels?
This is debatable, and you’ll get a different opinion from nearly every runner you ask. Follow the instructions on the gel package for the best results. All instructions aren’t always the same.
One general guideline that runners seem to follow regarding energy gels is this -- you should take one about 5 or 10 minutes before the start of a long race, with some water. Unless your package says differently, you should take one energy gel packet about every 45 minutes or so.
Once you take it during your race, you should feel extra pep in your step just minutes later.
Try Out Different Flavors
You don’t want to wait until you’re at the start of your marathon to realize you don’t like the particular flavor or texture of the energy gel you just bought in bulk. Give some gels a test drive ahead of time to see if the flavor is something you can live with.
I wouldn’t say that any of the many energy gels I’ve tried are delicious enough that I’d want to eat them as a snack if I weren’t running. But there were definitely flavors I enjoyed more than the others.
I personally found I didn’t like the peanut butter flavor because my mouth was already dry from running. That just made it feel worse. My favorite was a cherry limeade flavor I found because it felt refreshing to me.
Everybody has their own favorite, so keep that in mind when you get recommendations from a running buddy. Buy one pack at a time, even if your friend swears by her brand. You don’t want to be stuck with a lifetime supply of energy gel packets that you can’t manage to choke back because you hate the flavor.
The 5 Best Running Gels
1. Clif Shot Energy Gel
Clif Shots are popular with runners because they are made primarily from organic ingredients. They come with or without caffeine so you can find the formula for you. One formula might make you feel more like you can tackle the road ahead of you better.
