Review summary

Tailwind Endurance Fuel is a carb/electrolyte drink mix (25 g carbs/serving; no caffeine; 310 sodium). All-in-one endurance drink mix with ~25g carbs and ~300mg sodium per scoop — designed for drink-based fueling when you want calories and electrolytes in the same bottle without separate gels every mile. I'd shortlist it for carbs + higher sodium in one scoop simplifies bottle plans.

The trade-off is single scoop (~25g carbs) is not a Maurten 320-style high-carb hit — Skratch Labs Sport Hydration Drink Mix is the cleaner compare when that is most of your week. It fits buyers who actually need a carb/electrolyte drink mix (25 g carbs/serving; no caffeine; 310 sodium), not a one-product rotation.
