POPSRunning Doc: "Do the salt" to avoid hyponatremia More: * Follow the fluid recommendations….drink only when thirsty! * Include pretzels or a salted bagel in your pre-race meal. * Favor a sports drink that has some sodium in it over water, which has none. * In the days before the race, add salt to your foods (provided that you don't have high blood pressure or your doctor has restricted your salt intake). * Eat salted pretzels during the last half of the race. * Do the salt! Carry two small salt packets with you (the kind found in fast food restaurants), and before the race and again during the last half of the race (marathon or half-marathon) consume a single packet under your tongue. * After the race, drink a sports drink that has sodium in it and eat some pretzels or a salted bagel. * Stop taking non-steroidal anti-inflammatories 24 hours before your race and do not start again until 6 hours post-race.
