See a doctor: It is very difficult to answer intelligently because it would require an extensive history, a physical exam and some basic laboratory tests to even begin to have a clue. Feeling rundown is as vague a symptom as there is. It is also unclear where you live, how far you run and what other features of your life may play a role. Good luck. Suggest a primary care doctor to start with.
