The Importance of Salt in Race Training

Most people will be losing about 1000 milligrams of sodium per liter of sweat. At a race like Leadville, it's so high and it's so dry that you could easily be losing two liters an hour of sweat. If someone's in a bad way and we know that they just haven't been getting enough sodium during the event, we'll give them chicken broth or bone broth to bring them back. Instead of telling athletes to try to drink more water for those who seem to be under drinking, we just add more sodium.
