Energy Chews vs Gels: Which Should You Use?

Same absorption, different behaviour. Here is where each one wins, including where gels beat us.

Do energy chews absorb slower than gels?

No. Once carbohydrate reaches your small intestine, your transporters govern absorption, and they do not care whether it arrived as a liquid or a solid. Pfeiffer and colleagues ran gels, drinks and solids head to head across three hours of cycling and found oxidation rates effectively identical.

What actually separates them

Where chews win

Dosing. Six cubes means you choose how much and when. Three now, three in twenty minutes. A gel gives you one decision and you have already made it.

Mess. Nothing leaks into a jersey pocket. Your bars stay clean and your bib survives.

Wanting it at hour four. Sweetness fatigue changes races. Once fuel turns unpleasant you start rationing, and rationing at hour four is where the wheels come off. We went into the mechanism in why your fuel tastes worse at hour four.

Where gels win

Intensity, and this matters. Above threshold, in the last 10K of a marathon, chewing is work your breathing cannot spare. A gel asks nothing of you.

Gels also hand up easily, sit in every feed station and turn up in any shop in any country. We sell chews and all of that still holds.

What about price?

Per gram of carbohydrate the two sit closer than people assume. C.O1 runs €27.50 for twelve strips, so €2.29 a strip for 48 g, which lands near €0.05 per gram. Most branded gels fall between €0.06 and €0.10.

Price decides whether you take a full dose or a careful one. A fuel you ration has already failed, whatever the label claims.

So which should I use?

Carry both. Chews through the steady hours, a gel for the final effort. Choosing one? Choose against whatever makes you skip doses. Taste sends you to chews. Intensity sends you to gels.

Then rehearse it in training months out, the same as anything else you plan to do on race day.
