Some runners (and other athletes) have experienced a feeling of total wellness and sense of euphoria after engaging in intense physical activity. This feeling has come to be known as runners high. What is this runners high and how can we experience more than a runners high? "Psychologically, runners may experience euphoria, a feeling of being invincible, a reduced state of discomfort or pain, and even a loss in sense of time while running," says Jesse Pittsley, PhD, president of the American Society for Exercise Physiologists.*
