Tailwind Nutrition Endurance Fuel Drink Mix is a drink mix with 25 g of carbohydrate, 303 mg of sodium and no caffeine per serving. It scores 69/100 on the CarbRate Science Score. At 60 g of carbs per hour that is 2.5 servings an hour.
Who Endurance Fuel Drink Mix suits
Runners fueling below about 60 g per hour. Without a fructose source, absorption tops out near 60 g/hr, so stacking servings past that point tends to cause gut trouble rather than more energy.
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. 303 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 2.5 servings per hour; at 90 g/hr it is 3.5.
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 $2.47 per hour at list price, or roughly $9 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.
Single-source glucose/maltodextrin — reliable, but absorption is capped near 60 g/h without added fructose.
25 g carbs per serving — light for a drink mix (you'll need more units per hour).
No protein — ideal for during-race carbohydrate delivery (nothing slowing gastric emptying).

Endurance Fuel Drink Mix FAQ
Is Tailwind Nutrition Endurance Fuel Drink Mix good for a marathon?

How many Endurance Fuel Drink Mix should I take per hour?
2.5 servings per hour gets you 60 g of carbohydrate; 3.5 gets you 90 g. Each serving is 25 g. Space them evenly rather than front-loading.

No. It is caffeine-free, so you can take it every serving without stacking caffeine.
