Have you overtrained?

I know I've overtrained when I have sleep pattern disturbance, elevated heart rate even during rest, poor appetite and moodiness. My legs will feel heavy, with a deep fatigue, and just grocery shopping wears me out.

My last bout of overtraining hit me in March. I had been riding all year, even through the first weeks of February. I was on my mtb doing easy trails and it snuck up on me anyway. I had to lay off for a whole month.
