The short version

Science in Sport Beta Fuel Gel is a gel with 40 g of carbohydrate, 30 mg of sodium and no 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 one and a half servings an hour.

Fit

Who Beta Fuel Gel 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 want fewer servings to carry. At 40 g per serving, an hour at 90 g/hr is 2.5 servings, which matters over a marathon or ultra where pocket space and hand-offs are real limits.

Runners who want to keep caffeine separate, or race caffeine-free. Caffeine-free fuel is easier to repeat every 20 to 30 minutes without stacking a stimulant.

Runners who handle sodium separately. At 30 mg per serving this is a carbohydrate source first, so heavy sweaters will want electrolytes from a drink or capsule alongside it.

Race day

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 one and a half servings per hour; at 90 g/hr it is 2.5.

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 $4.13 per hour at list price, or roughly $14 for a three-and-a-half hour marathon.

Servings per hour assume the 40 g per serving on the label. The finder sets your own g/hr target from race distance, sweat and gut.

RC Science Score · 100/100

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.

Carbohydrate quality45/45

Dual-source carbohydrate at a ~1.25:1 glucose:fructose ratio — inside the evidence window that lifts the absorption ceiling toward 90 g/h.

Carbohydrate dose20/20

40 g carbs per serving — a full working dose for a gel.

Race-appropriate (protein-light)20/20

No protein — ideal for during-race carbohydrate delivery (nothing slowing gastric emptying).
