Why are Hydration and Electrolyte replenishment so important to training?
When you commit to a marathon or half marathon training program you commit to a lot of running. When you run you perspire and when you perspire you lose essential nutrients involved in muscle recovery. In other words, if you do not replenish those nutrients before, during, and after exercise you will feel sore, tired, and run-down. Besides water, you should be consuming energy drinks and gels. These provide the electrolytes that water does not. Practicing water stops during your everyday runs is also a good way to practice for race day when you should be taking water at every station and trying to take in as much as 70 ounces during the entire race.
