To carry energy gels during a marathon, you need a method that keeps them secure, within easy reach, and free of bounce for 26.2 miles. This guide walks you through the main carrying options, how to load them, and how to test your setup before race day so nothing surprises you at mile 18.
Decide How Many Gels You Need to Carry
Start with your fueling plan, not your gear. Most marathoners aim for roughly 30 to 60 grams of carbohydrate per hour once the run passes about 60 minutes, and many gels provide around 20 to 25 grams each. Check the label on your chosen gel, then work out how many you will need over the full distance. For a 3:45 finish, that usually means three to four gels, so carry at least one spare in case of dropped or sticky packets.
Compare the Main Carrying Options
Each method trades off accessibility, bounce and weight distribution. Choose the one that matches how you already run.
| Method | Best for | Watch out for |
|---|---|---|
| Race belt with gel loops | Quick one-handed access | Can shift if loosely fitted |
| Shorts or tights pockets | Runners who want nothing extra | Gels may slip out or warm up |
| Bib-belt or hip pack | Carrying several gels at once | Adds visible bulk |
| Hand-held flask | Runners who already carry water | Occupies one hand |
| Sports bra or chest pocket | Keeping gels cool and close | Harder to reach while moving |
Load and Secure Your Gels Correctly
Once you have a carrier, the way you load it matters as much as the carrier itself. Follow these steps:
- Tear the top of each packet slightly before the race so you can open it with one hand without stopping.
- Place the gels with the tear-tabs facing outward so you can grab and open them quickly.
- Stagger the packets so they do not press into each other, which can cause leaks or squeezing.
- Test the fit by running at least 3 miles with the full load, then adjust the belt or pocket position.
- Keep one gel in an accessible spot and the rest in a secondary pocket, so you never have to dig.
Prevent Bounce, Leaks and Heat Damage
Bounce creates chafing and makes gels harder to grab. Tighten your belt until it stays put when you jog in place, not so tight that it digs in. Gels also thin and become more fluid in heat, so avoid sealing them in a closed bag where they can warm up. If you run in hot conditions, consider a carrier with ventilated loops or carry gels in a front pocket where air circulates. Consult a sports dietitian or your physician if you have digestive issues or a history of gastrointestinal problems during long runs, since gel tolerance varies widely.
Common Mistakes
- Carrying gels for the first time on race day. Always train with your exact setup.
- Packing too many gels in one pocket, which causes bounce and uneven weight.
- Waiting until you feel thirsty or tired to reach for a gel. Take it on schedule.
- Forgetting to open the packet before a hill or turn where your hands are needed for balance.
- Using a belt that has never been worn at race pace, leading to rubbing by mile 15.
Recommended gear
A race belt with gel loops keeps packets close and stable, making it a practical first choice for most marathoners. View on Amazon
A small hand-held flask suits runners who want to carry gel and fluid together without wearing extra layers. View on Amazon
A lightweight hip pack with stretch pockets works well when you need to carry several gels plus a phone or keys. View on Amazon

FAQ
Can I carry gels in my shorts pocket during a marathon?
Yes, many runners do, but gels can slip out or warm up in a pocket that is not secured. Test the pocket on long training runs first to confirm the gels stay put.
How many gels should I carry for a marathon?
Calculate your total carbohydrate need per hour and divide by what one gel provides. Most runners carry three to four gels, plus a spare.
Should I open my gels before the race?
Tear the top slightly so you can open them with one hand, but do not fully open them. Fully opened packets can leak or dry out before you need them.
Conclusion
Choose a carrier that matches your running style, load your gels so they are easy to grab, and test the full setup on long training runs. A well-secured gel is one you will actually take on time, which is what keeps your energy steady through the final miles.
