The Oregon Marathon and Half Marathon encourages you to hydrate properly.  The following is a guide by American College of Sports Medicine that could be used in your pursuit of hydrating properly.


Exercise and Fluid-Replacement Standards


Athletes are encouraged to drink early, and at regular intervals rather than rapid-fluid replacement.


Thirst May Not Be Enough: Perception of thirst is an imperfect index of the magnitude of fluid deficit, and cannot be used to provide complete restoration of water lost by sweating.


Monitor Body Weight Loss: Individuals participating in prolonged intense exercise must rely on strategies such as monitoring body weight loss and ingesting volumes of fluid during exercise at a rate equal to that lost from sweating to ensure complete fluid replacement.


Drink Consistently Rather Than Taking a Big Drink Break: Drinking over a set period of time is more effective for complete rehydration vs. rapid replacement of fluid, which instead stimulates increased urine production, reducing body-water retention.


Sweat Fluid Loss: If athletes are not sweating heavily (such as slow runners), and are not thirsty, then their fluid replacement needs are probably modest.


Consume Salty Foods and Beverage: Research shows foods and beverages with sodium help promote fluid retention and stimulate fluid intake. Athletes performing prolonged exercise should ingest snacks or fluids containing sodium to help offset the loss of salt in sweat in an effort to prevent hyponatremia.
