Running and Overtraining
While there’s debate about what to call it and less than a consensus about some of its medical aspects, Overtraining Syndrome or Adrenal Fatigue is a condition generally caused by overtraining and/or over racing that results in significant or debilitating fatigue that affects not only one’s running, but also day-to-day life.
A good place to start a look into overtraining is Joe Uhan’s three-part series Overtraining Syndrome: An Overview, Overtraining Syndrome: Treatment and Prevention, and Overtraining Syndrome: Trail Ultrarunning Specifics, as well as Corrine Malcolm’s Beyond Fatigue: Understanding Overtraining Syndrome.
There’s also the possibility that overtraining syndrome is something else. Find out more, Is Your Overtraining Syndrome Really Relative Energy Deficiency in Sport (RED-S)?
