Roctane Energy Drink Mix

GU Energy Roctane Energy Drink Mix is a drink mix with 60 g of carbohydrate, 320 mg of sodium and no caffeine per serving. It scores 92/100 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 about one serving an hour.

Who Roctane Energy Drink Mix 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 60 g per serving, an hour at 90 g/hr is one and a half 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.

Heavy or salty sweaters and hot-weather races. 320 mg of sodium per serving covers a good share of typical sweat losses without a separate electrolyte product.

Runners with dietary limits: it is vegan and gluten-free 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 about one serving per hour; at 90 g/hr it is one and a half.

Drink texture, so it goes down without much water. Still sip at aid stations; carbohydrate absorbs faster when the stomach has fluid to work with.

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 $2.25 per hour at list price, or roughly $8 for a three-and-a-half hour marathon.

Servings per hour assume the 60 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
