How to Hydrate for a Race

Robert Kineffik, PhD is a research physiologist at Ucerium. His work focuses on environmental physiology including heat, cold and altitude. He says the most important thing to know about hydration is that it's matched with fluid intake. The majority of body water is distributed through three compartments in your body: intracellularly inside the cells, extracellularly within the cells and extra solute fluid around yourself.
