i'm an ultrarunner and in the past, i have always struggled with getting nauseous fifty miles into every race. I started using Tailwind for my sugar/salt/calories instead of trying to eat food with I have palette fatigue. It it the ONLY THING THAT WORKS FOR ME. I cannot say enough good things. If you tend to get sick of everything, Naked flavor is the way to go. Just won my first 100 mile race last weekend and I used Tailwind every single step of the way.
