The Tailwind Endurance Fuel is fantastic and I will never drink anything else on a run. I recently ran half marathon and took the Gatorade at two of the refueling stops. What a mistake. By mile 11 my stomach was not happy with me. I searched for alternatives and found Tailwind. I drink it on all of my long runs now. It gives me the fuel to feel great during my runs and it is tasty! My stomach loves me know!
