Forget Gatorade. The sport drink of choice now comes in a dissolving tablet. Dropping the unwanted sugars that make Gatorade and other endurance beverages hard to swallow, Nuun delivers the electrolytes your body needs while lightly flavoring your water with a hint of lemon and lime, orange and ginger, citrus fruits and more.
Assuming you can find safe water replenishment sources along your route, Nuun's clever capsule packaging—12 tablets in one little tube—eliminates the waste from as many plastic bottles. At $6.50 a tube (roughly 50 cents per 16 oz. drink), you'd be hard pressed to find a more economical sport drink.
