Tailwind's High Carb Fuel pushes the carbohydrate ceiling higher than the original Endurance Fuel, delivering 100 grams of carbs per serving for riders chasing the 90-120 grams per hour intake targets that have become standard practice in endurance racing. The dual-source carbohydrate blend uses glucose and fructose in a 1:0.8 ratio, which lets your gut absorb more total carbohydrate per hour than glucose alone by recruiting separate transport pathways in the small intestine.

The 16-serving pouch works out to roughly 16 hours of fueling at one scoop per hour, though most riders mix 1-2 servings per bottle depending on intensity and duration. Each serving dissolves cleanly in 24 ounces of water without the chalky residue that plagues some high-carb mixes. The flavor stays light and slightly sweet rather than syrupy, which matters when you're forcing down bottle after bottle in hour six of a gravel race or gran fondo.

Sodium content sits at 400mg per serving, which covers electrolyte needs for most riders in moderate conditions without requiring separate salt supplementation. If you're racing in heat or known to be a heavy sweater, you may still want to add electrolyte capsules. The formula is non-GMO, vegan, gluten-free, and free from soy and dairy, which keeps it accessible for riders managing dietary restrictions.... Read More
