Calories, electrolytes, and hydration in one bottle with nothing to unwrap mid-ride. Tailwind Endurance Fuel eliminates the pocket full of gels and chews that complicate long efforts, replacing everything with a drink mix that delivers 200 calories per packet alongside 620mg of sodium and a full electrolyte profile. The formula uses dextrose and sucrose as its carbohydrate sources, matching what your body already uses for fuel so absorption happens quickly without taxing your digestive system. That simplicity translates to fewer stomach issues when you're hours into an event.

Each single serving packet mixes with 18-24oz of water and dissolves instantly without residue. The Endurance Fuel stays clear in your bottles and hydration packs, which matters when you're refilling at aid stations or washing gear after a long day. Tailwind designed the flavors to taste good at hour six, not just hour one. The light, clean profiles avoid the cloying sweetness that makes some drink mixes hard to tolerate as efforts extend into the afternoon. If you've ever struggled to finish a bottle late in a ride, this matters.

The 12-pack format works well for testing flavors before committing to larger bags, or for stashing packets in jersey pockets and race bags where pre-measured portions simplify logistics. Non-caffeinated options include Mandarin, Lemon, Berry, and Naked (unflavored), while Raspberry and Tropical add 70mg of organic caffeine per packet for efforts where you want the boost. The ingredient list stays short: non-GMO dextrose, non-GMO cane sugar, citric acid, sodium citrate, sea salt, potassium chloride, natural flavors, calcium carbonate, and magnesium oxide. No dyes, no preservatives, no gluten, dairy, or soy.
