Can You Take Gels Through TSA? A Runner’s Guide to Flying With Energy Gels

Can You Take Gels Through TSA? A Runner’s Guide to Flying With Energy Gels

If you are flying to a marathon, half marathon, or another race, you might end up staring at a pile of energy gels and wondering whether TSA is going to confiscate your race fuel.

Can You Take Gels Through TSA? The short answer is yes, you can take running gels through TSA.

There are restrictions, though. TSA classifies energy gels with liquids, gels, creams, aerosols, and pastes. If you are packing gels in your carry-on luggage, each container needs to be 3.4 ounces, or 100 milliliters, or smaller. Those gels need to fit within your quart-sized bag along with the other liquids you are bringing through security.

Most individual running gels fall comfortably below the 3.4-ounce limit. The bigger concern for runners is usually the number of gels they are bringing and how much room those packets take up alongside toiletries, sunscreen, toothpaste, and everything else that needs to go into the same liquids bag.

TSA has its current carry-on liquid rules listed on its official TSA travel page.

Do Energy Gels Count as Liquids for TSA?

Yes. TSA includes gels under its 3-1-1 liquids rule.

Running gels might have a much thicker consistency than a drink, but that does not move them into the solid-food category. Traditional energy gels, hydrogels, fruit-based gels, and similar running fuel should be packed with your other carry-on liquids. Pack your gels in a clear ziploc bag incase they get punctured (I’ve learned this the hard way).

This applies whether you are bringing GU, Maurten, Precision Fuel, SIS, Neversecond, UCAN, or another type of packaged gel.

Most individual gel packets are much smaller than 100 milliliters. For example, you are unlikely to have an issue bringing a handful of standard single-serving gels based on the size of each individual packet.

The question changes when you are carrying enough fuel for several days of running or a long-distance race. When we went to Australia, between my spouses biking and my running…we had a lot.

How Many Running Gels Can You Bring Through TSA?

TSA does not publish a rule that says runners can bring exactly six gels, ten gels, or any other specific number.

The restriction comes from the 3-1-1 rule.

Each gel needs to meet the individual container limit, and your carry-on gels need to fit with the other liquids you are taking through security.

For a 5K or 10K trip, this may not require much thought but a marathon is different, especially if you are targeting a higher carbohydrate intake and bringing several gels for race morning. Add pre-race fuel, backup gels, post-race nutrition, and the products you plan to use during shakeout runs, and the pile can grow quickly.

If I am flying to an important race, I want enough race fuel in my carry-on to get through race day even if my checked bag disappears somewhere between airports.

My tip for bringing gels through TSA? I would pack my planned race gels plus a couple of extras in my carry-on and move any additional supply into my checked luggage.

Can You Put Running Gels in Checked Luggage?

Yes.

If you need to bring a large quantity of gels, checked luggage can make traveling much easier. The TSA carry-on 3.4-ounce liquid restriction does not apply in the same way to products packed in checked baggage. I still would not put every single race gel in a checked suitcase.

Delayed luggage is annoying on any trip…especially if you have spent months practicing with a specific nutrition plan and suddenly need to find your exact gel the day before a race.

Keep your race-day supply with you and pack the extras in your checked bag.

For runners with sensitive stomachs, replacing a familiar gel may be harder than grabbing whatever brand happens to be at a race expo. I have a separate guide to the best running gels for sensitive stomachs if you are still figuring out which options agree with you.

Can you bring gel flasks through TSA?

Not always. You can’t always bring massive gel flasks through TSA.

Some runners combine multiple servings of gel into a reusable flask rather than carrying individual packets. Before packing one in your carry-on, check the flask’s capacity. We love being environmentally friendly, but it means being smarter with how you pack things.

If the container is larger than 3.4 ounces or 100 milliliters and contains gel, it may not meet TSA carry-on requirements.

An empty flask is better. Pack the empty flask in your luggage, bring TSA-compliant individual packets, and fill the flask once you arrive at your destination. You can also pack a larger filled flask in checked luggage.

For anyone who races with a gel flask regularly, I would check the printed capacity instead of guessing based on how small it looks.

Can You Bring Energy Chews Through TSA?

Energy chews, waffles, bars, and other solid running foods can be easier to travel with because TSA permits solid food in carry-on luggage. That makes products such as energy bars and waffles easier to pack when your liquids bag is already full.

Chews can fall into a slightly murkier category depending on their consistency and packaging. If a product is particularly soft or gel-like, I would check the specific item with TSA before traveling rather than assume it will be treated exactly like a solid candy.

TSA maintains its searchable What Can I Bring? database, and AskTSA can answer questions about products that do not fit neatly into one category.

Should You Take Race Gels in Your Carry-On?

For a destination race, I would.

You should always pack your race shoes, race clothes, and race nutrition in your carry on. Ask yourself: would not having this item devastate me for the race? If the answer is yes, then pack it in your carryon. Most other things can be purchased after landing if luggage gets delayed.

Your fueling plan is harder to replace, particularly if you have spent months training your stomach to handle a specific product. I have tested several types of endurance fuel over the years, including Precision Fuel and UCAN Edge. Once I know what I want to race with, I do not want airport logistics deciding that I need to switch products.

Put the gels you need for race day in your carry-on. Bring a few extras in case one breaks, leaks, or goes missing. If you are carrying far more than you need for the race itself, divide the remainder between your bags.

Can You Take Gels on International Flights?

TSA rules apply to security screening in the United States.

If you are flying internationally, the airport you use for your return flight may operate under different liquid restrictions. Many countries have similar 100-milliliter limits, but you should check the rules for the country and airport you will be departing from rather than assuming TSA regulations apply everywhere. This is especially relevant if you are traveling overseas for a marathon and plan to bring leftover gels home.

Customs and agricultural rules are separate from airport security rules as well. Certain food products can have additional restrictions when crossing international borders.

Can You Take Gels Through TSA?

Yes. Running gels can go through TSA in your carry-on luggage when each container is 3.4 ounces or 100 milliliters or smaller and the gels comply with TSA’s 3-1-1 liquids rule.

Most standard individual energy gel packets are below that size limit. If you are traveling with a large quantity of race nutrition, keep the gels you need for race day in your carry-on and put additional fuel in checked luggage. Solid running foods such as bars and waffles are generally easier to pack because they are not subject to the same liquid limit.

Flying to a race already involves enough packing. Check your gels before leaving home, keep your race-day fuel with you, and you can get through airport security without having to rebuild your nutrition plan after you land.
