** Any errors in fueling can cause problems with digestion, which in turn prevents adequate hydration.
** Failure to reduce running intensity in hot weather can cause the core body temperature to rise, which causes nausea, which prevents hydration.
** Getting the salt intake wrong will cause hydration problems. Taking insufficient salt will cause thirst, but anything you drink will tend to increase urine output without reducing the thirst. (Too much salt can cause nausea and bloating. Excessive salt seems to be related to electrolyte capsules[[Electrolyte Capsules]].)
* '''Fueling'''. Most runners require some type of calorie intake for the marathon distance. For ultra distances, fueling becomes critical. You must learn what your body likes, as this tends to vary for each individual. As noted above, getting fueling wrong will lead to digestive problems (nausea/vomiting) which can then cause hydration problems. The other common problem is that lack of fuel can lead to a drop in blood sugar. This is particularly problematic as the brain needs the sugar to work correctly. The lack of blood sugar then causes poor judgment and also a feeling of depression. See [[Fueling in an Ultra]]
