Pre:play combines clinical strength hydration with a time released energy boost.
pre:play allows your body to burn fat as a fuel source versus using the glucose in your muscles and liver, allowing you to sustain a prolonged level of work capacity. Your muscles and liver only contain 400 grams of glucose/glycogen that's less than 1lb! Everybody has more than 1lb of fat energy. When you are burning fat as an energy source, no breaking in the middle of a race!
