As the temperatures soar, we all know how important it is to stay hydrated on long runs. Equally important, when you are running distance is to replace electrolytes. But what do you do if you want to avoid those sugar laden energy drinks? This is a terrific product my husband originally found for his trips to high elevation in Peru. He's diabetic and can't take sugary performance drinks. Nuun makes these tablets you simply drop in your water bottle. They only take about 2 minutes to completely dissolve and they taste great - kind of like watered-down citrus (they come in a couple of different flavors.) Easy to pack and lightweight!
