Hard to beat
Fuel20 makes a real difference in my long endurance bike rides and hikes. Doesn't upset my stomach and tastes great! I have a hard time eating after 4-5 hours in the saddle or on the trail, so I appreciate Fuel2O's ability to keep me going even when I don't have an appetite for physical food.
