Name: Tailwind Endurance Fuel Drink Mix
Brand: Tailwind Nutrition

ARC research verdict

Tailwind Endurance Fuel is a drink-mix option for runners who would rather take a substantial share of their carbohydrate fuel through a bottle or hydration reservoir than carry only gels. It combines carbohydrate with electrolytes and comes in stick packs and multi-serving bags. It is useful to compare for long runs, trail races and ultras, especially where refilling water is practical. It is not a guarantee against stomach trouble, and mixing concentration matters.

Verified formula and serving

Tailwind's Asian distributor describes a mixture based on dextrose (glucose) and sucrose, with sodium citrate, sea salt, potassium chloride, magnesium and calcium sources. The standard endurance serving is commonly described as two scoops or one stick pack, around 200 kcal and 50 g carbohydrate, mixed into roughly 500–750 ml of water according to pack and regional guidance. Follow the actual label rather than applying one mixing ratio to every packet size or formulation. A single scoop is a smaller serving.

Some flavours are caffeinated, while others are not. The regional distributor lists Raspberry Buzz, Green Tea Buzz and Tropical Buzz among caffeinated options; other retailer ranges can include Cola. A Singapore retailer describes 35 mg caffeine per 100-kcal serving for its caffeinated version. That means caffeine intake depends on how much powder you use, so check the exact flavour and local nutrition panel before mixing.

Who it suits

Runners who dislike eating frequent gels may appreciate sipping their fuel, but the trade-off is that fluid and carbohydrate are carried together. That can be inconvenient if you need more water than fuel, or vice versa. You may still want plain water, food or separate electrolyte options depending on the course and your own plan. Avoid assuming the brand's 'all-in-one' positioning means it is the correct sole nutrition source for everyone.

An independent Trail Run Magazine account describes using the mix over a long race and finding the flavour manageable. This is one runner's experience, not an ARC trial or a promise of digestive tolerance.

Preparation, carrying and care

Practise measuring the mix with your actual bottle or bladder. Shake with clean water and check that it dissolves before starting. When racing in humid Asian conditions, consider how you will refill, clean your equipment and store opened powder away from heat and moisture. A flavoured carbohydrate drink left in a reservoir requires careful cleaning afterwards. Do not use a new fuel system for the first time during a target event.

Model and buying checks

This listing covers Endurance Fuel, with flavour, caffeine choice, stick packs and bag sizes treated as variations of one product model. Tailwind High Carb Fuel and Rebuild Recovery are different formulas. Confirm the exact product, carbohydrate per measured serving, caffeine, allergens, best-before date and the local retailer's shipping region. Red Dot Running Company provides Singapore listings; Tailwind Nutrition Asia and Hillmalaya cover Hong Kong. The Indonesia link is an affiliate marketplace search, not a verified seller; the Malaysia marketplace link likewise requires seller and expiry checks. Some Singapore retailer variants were marked sold out at research time.
