Maurten Gel 100 CAF 100 is a gel with 25 g of carbohydrate, 22 mg of sodium and 100 mg of caffeine per serving. It scores 100/100 on the CarbRate Science Score, helped by a dual-source glucose and fructose blend that raises how much carbohydrate the gut can absorb per hour. At 60 g of carbs per hour that is 2.5 servings an hour.
Who Gel 100 CAF 100 suits
Runners fueling at 60 g of carbohydrate per hour or more. The glucose plus fructose blend uses two absorption pathways, so more of what you swallow gets used and less sits in the stomach.
Runners who use caffeine during a race. 100 mg per serving is a large dose; one serving is enough for most people, and it is best used in the second half rather than every hour.
Runners who handle sodium separately. At 22 mg per serving this is a carbohydrate source first, so heavy sweaters will want electrolytes from a drink or capsule alongside it.
Runners with dietary limits: it is vegan according to the manufacturer.
How to use it in a race
Start early. Take the first serving 15 to 20 minutes into the race, before you feel you need it, and repeat on a fixed clock. At 60 g/hr that is 2.5 servings per hour; at 90 g/hr it is 3.5.
Thick gel texture. Take it with two or three mouthfuls of water so the carbohydrate is diluted enough to leave the stomach quickly.
Practice it on long runs at race intensity before you race on it. Gut tolerance is trained; a fuel that felt fine at easy pace can behave differently at marathon effort.
Cost at 60 g/hr works out to about $10.39 per hour at list price, or roughly $36 for a three-and-a-half hour marathon.
Servings per hour assume the 25 g per serving on the label. The finder sets your own g/hr target from race distance, sweat and gut.
Why it scores what it does
Computed from verified label data with the same evidence rules for every product. Retailer relationships play no part in the score.
Dual-source carbohydrate at a ~1.25:1 glucose:fructose ratio — inside the evidence window that lifts the absorption ceiling toward 90 g/h.
25 g carbs per serving — a full working dose for a gel.
No protein — ideal for during-race carbohydrate delivery (nothing slowing gastric emptying).
