Take your first energy gel about 30 to 45 minutes into a long effort, then one every 20 to 40 minutes after that — a pouch roughly every half hour. The key is starting before you feel empty: carbs take 10 to 15 minutes to reach your bloodstream, so if you wait until you're fading, you're already behind. Steady and early beats big and late.
When should you take your first gel?
For most efforts over about an hour, take your first gel around 30 to 45 minutes in. Your body starts with roughly 90 minutes to two hours of stored carbs, so fueling early — while the tank is still full — keeps your blood sugar topped up instead of trying to claw it back once it drops. For shorter sessions under about 60 to 75 minutes, you usually don't need a gel at all; your own stores cover it. The longer the day, the more it pays to start on time.
Should you take a gel before the start?
The deciding factor is whether your tank is already topped off. If you've eaten a normal carb-focused meal in the last couple of hours, your glycogen stores are full and you don't need a pre-start gel. But if you haven't eaten in a while — an early start, a skipped or light breakfast, or hours since your last meal — your stores aren't topped off, and a single gel about 15 minutes before the start is a good idea to fill them back up. Either way, take it with a little water. What matters more than the pre-start gel is not skipping the early in-race ones.
How often should you take gels after the first?
Once you've started, keep them coming every 20 to 40 minutes — a pouch about every half hour is an easy rhythm to hold. That works out to two to three gels per hour, which covers most runners, cyclists, and triathletes. Take each one with a few sips of water so it absorbs smoothly. In the early miles you'll feel fine and it's tempting to skip — that's exactly the trap, so set a watch alarm if you're forgetful. For how the amount adds up, see how many carbs per hour you need.
When should you take a caffeinated gel?
Time caffeine for when you want the lift, not the moment you take it. Caffeine takes roughly 30 to 60 minutes to kick in, so a caffeinated gel taken before the hard final third of a race lands right when you need it. A common approach: use caffeine-free gels early, then switch to a caffeinated one later. Hüma's caffeinated flavors carry 25mg each — about a third of a small coffee — while Double-Shot Mocha delivers 100mg for a bigger jolt. See the Hüma flavor guide for which flavors are caffeinated.
When should you take your last gel?
Stop fueling a little before the finish, not at it. Because carbs need 10 to 15 minutes to reach your bloodstream, a gel taken in the final few minutes won't do much for you. On a marathon, your last useful gel lands around 20 to 30 minutes before the line. Anything later is for your head, not your legs.
Timing your gels with Hüma
The Hüma rhythm is simple: two to three per hour — one every 20 to 30 minutes — starting around 30 to 45 minutes in, each with a few sips of water. Real-food carbs from brown rice syrup and cane sugar, with real fruit and chia, and more water in the formula than a thick syrupy gel, so they go down smooth even deep into a long effort. Practice your timing on long runs so race day is automatic — see how to fuel your first marathon for a full race-day plan.
FAQ
When should you take your first energy gel?
About 30 to 45 minutes into an effort over an hour — early, while your carb stores are still full, rather than waiting until you feel empty.
How often should you take energy gels?
Every 20 to 40 minutes after the first — a pouch roughly every half hour, or two to three per hour. Take each with a few sips of water.
Should you take a gel before the race start?
It depends on whether you're topped off. If you've eaten a carb-focused meal in the last couple of hours, you're full and don't need one. If you haven't eaten in a while — an early start or skipped breakfast — a gel about 15 minutes before the start tops your glycogen back up.
When should you take a caffeinated gel?
Roughly 30 to 60 minutes before you want the lift, since that's how long caffeine takes to kick in — often before the hard final third of a race.
When should you take your last gel?
Around 20 to 30 minutes before the finish. Carbs need 10 to 15 minutes to reach your bloodstream, so a gel in the final few minutes won't help your legs.
