In brief: Stay Hydrated
Dehydration can lead to dry mouth, thirst, headaches, dizziness, fatigue, cramping, or less coordination during exercise.
Rather than look for signs of dehydration it is better to pre-hydrate in the days or hours before major exercise or a major run and to hydrate during exercise. The general rule of thumb is to drink when thirsty during exercise.
