A gel with 80 mg of caffeine and 50 g of carbs in a 76 g pouch is race-day fuel, not a casual training snack. The 226ERS High Energy Gel Coffee flavor lands in the English-speaking running world carried by the Spanish brand's reputation among triathletes and cyclists, far less known among road and trail runners. At RunMorph, the question is simple: does this gel hold up against the references we've already tested, Overstims and GU?

The 226ERS High Energy Gel Coffee packs 50 g of carbs and 80 mg of caffeine into 76 g, a denser dose than most gels sold in Europe. The formula relies on cyclodextrin alone rather than a dual-carb blend, which speeds gastric emptying but removes the usual fructose backup once you go past 60 g of carbs an hour. At 3.50 EUR a unit, this is a race-day gel, not an everyday training one.
226ERS was born in Alicante, built around the Ironman distance (226 kilometers, hence the name) before expanding into cycling and, more recently, running. The brand still sits in the shadow of Maurten, GU, or Overstims on running-focused shelves, even though it carries real weight among triathletes and cyclists. The High Energy Gel Coffee flavor makes a simple pitch: 80 mg of caffeine, roughly a strong espresso shot, in a format built for the back half of a race.
The range leans on cyclodextrin, a carbohydrate the brand presents as clearing the stomach faster than a classic maltodextrin-fructose blend. On paper, the logic holds up. What it delivers once swallowed mid-effort is harder to pin down, and that's where French and English-language press coverage of this specific product stays thin.
| Spec | Value |
|---|---|
| Brand | 226ERS |
| Model | High Energy Gel, Coffee Espresso flavor |
| Format | Soft pouch gel, 76 g |
| Carbs | 50 g, of which 24.1 g sugars |
| Carb source | Cyclodextrin, glucose syrup, maltodextrin, sucrose |
| Caffeine | 80 mg |
| Salt | 0.1 g |
| Energy | 200 kcal |
| Recommended use | 1 to 2 units per hour with about 300 ml of water |
| Price | 3.50 EUR per unit |
One number sums up the product's pitch: 50 g of carbs for 76 g of gel, against 22 to 27 g for most gels sold in supermarkets or sports stores. A Decathlon Energy Gel+ sits around 22 g, an Overstims Coup de Fouet around 26 g. The 226ERS gel is closer to concentrated formats like SiS Beta Fuel (40 g).
The difference comes down to the ingredient. Cyclodextrin is a cyclic molecule with a high molecular weight. A heavy mass dissolved in little water keeps the solution's osmolarity low, and low osmolarity speeds up gastric emptying: that's the logic 226ERS uses to justify such a dense dose without weighing digestion down. The trade-off is the lack of a dual-carb blend. Unlike SiS Beta Fuel, which pairs glucose and fructose, the 226ERS formula doesn't mix two sugar families. Past 60 g of carbs absorbed per hour, the gut needs two separate transport pathways to absorb sugar efficiently, and a single-carb gel then turns into a weakness rather than a strength.
RunMorph's advice: stay under the threshold where a dual-carb blend starts to matter. This gel works well taken on its own for a short to medium race, less so for stacking 3 or 4 gels an hour in an ultra.

Very few dedicated reviews of this exact coffee-flavor gel exist, despite a cross-search across French and English-language running sites. Press coverage of 226ERS stays concentrated on cycling and triathlon, not running. We're flagging this openly rather than hiding it: this section leans on a smaller pool of sources than usual, filled out with one detailed test of a gel from a different line by the same brand.
That test, run during a 20-kilometer fasted easy run, describes a thick texture and a taste the tester found quite sweet, with no digestive trouble at all. The product tested wasn't the coffee gel itself (the brand's organic line, different flavor), so this feedback speaks more to the range's general digestive tolerance than to this exact flavor's taste. Aggregated customer reviews from cycling and triathlon retailers converge on one point that holds across the whole range, flavor aside: the toothpaste-tube-style pouch doesn't reseal well once opened and works best taken in one go.
On the caffeine dose, nothing contradicts the spec sheet. The 226ERS gel's 80 mg sits well above the GU Roctane's 35 mg, without reaching the heaviest caffeine formats on the market, which climb past 100 mg.
| Spec | 226ERS High Energy Gel Coffee | GU Roctane | Overstims Coup de Fouet |
|---|---|---|---|
| Carbs | 50 g | 32 g | 26 g |
| Caffeine | 80 mg | 35 mg | not disclosed (royal jelly) |
| Texture | Thick gel, single carb source | Gel with added BCAAs, an ultra-trail staple | Liquid gel |
| Origin | Spain | United States | France |
The simple read: the 226ERS gel packs the highest carb and caffeine dose of the three, at the cost of a single-carb formula where GU Roctane leans on a blend built for ultra-distance. Overstims Coup de Fouet remains the safe French pick for anyone who prefers a liquid texture and a France-made brand.
With 50 g of carbs and 80 mg of caffeine, this gel earns its place on the long runs of a marathon block, especially past kilometer 25 when focus starts to slip. Pair it with your RunMorph Marathon plan to test digestive tolerance before race day, never for the first time in a race.
The 226ERS High Energy Gel Coffee delivers on its spec sheet: 50 g of carbs and 80 mg of caffeine make it one of the densest gels RunMorph has tested, at a price that stays in line with the premium market. The single-carb formula caps its use to a standalone dose or spaced-out intake rather than a string of gels in an ultra, and the scarcity of dedicated reviews on this exact flavor keeps us from being categorical about the taste. 7.5/10: a solid race-day gel for anyone after a strong caffeine hit, not yet an unquestioned reference for lack of enough field testing.
The 80 mg of caffeine make it a gel for runners already used to caffeine during exercise, not a first choice for a beginner who has never tried an energy gel.
The brand recommends 1 to 2 units per hour with about 300 ml of water, up to 100 g of carbs hourly, a high ceiling best reserved for runners trained to handle that load.
Its 50 g carb dose suits a long trail effort, but the lack of a dual-carb blend makes it worth alternating with a gel like SiS Beta Fuel (40 g, dual source) past 4 to 5 hours of effort.
The 226ERS gel packs 18 g more carbs and 45 mg more caffeine than GU Roctane (50 g vs 32 g, 80 mg vs 35 mg), but GU Roctane adds BCAAs that the 226ERS formula doesn't include.
