The focused, calm, and vital feeling that occurs with my daily runs is more a constant companion than the intermittent guest of the runner's high. My daily run has been one of my closest friends for over 40 years. It's helped me solve problems, guided me to some great ideas (as well as some ridiculous ones), accompanied me to the heights of ecstasy, and has humbled me on many occasions. It's been there after births and after deaths, after joy and after sorrow. But over my long running career, I can recall only a handful of times that I've gone beyond the more standard 'in the zone' type of feeling and experienced a true runner's high. Those few occasions have left me with blissful elation, experiencing a running rhapsody as though gliding on air with a flowing, effortless, and exultant feeling.
