Are you having problems sleeping?
Is getting up in the morning difficult?
Do you feel heavy-legged after a run?
Are you unusually tired or fatigued before, during or after a run?
Have you recently lost your desire to run?
Have you had any recent headaches, sniffles, sore throats?
Do you have any unusual aches or pains?
Are you exhausted after an easy run?
Do you have problems with your bowel movements?
Do you have menstrual irregularities?
If you answered yes to one or more of these questions, then you could be overtrained. If you answered yes to three or more, you are almost certainly overtrained.
What is your resting pulse? Is it your average?
How high above your average is it?
Seven to 10 beats above average probably indicates overtraining.
How much do you weigh?
How much did you weigh yesterday? The day before?
A two- to three-pound loss in weight in one day could be a sign of impending injury.
How much sleep do you normally require?
Have you been able to get that amount lately?
Have you been working harder? Under more stress lately?
Has this interferred with your ability to rest or get enough sleep?
Consistent decreased hours of sleep will lead to injury within a few days.
Have you been unusually thirsty lately?
Have you noticed an unusually greater fluid intake than normal?
Increased need for fluid intake often leads to injury in a few days.
Has your urine changed in color (become darker) or in odor (obtained one all of a sudden)?
This could be a sign of overtraining.
When in doubt, cut back on your running. You're better off taking it easy for a few days than having to take time off due to an injury. Try to listen to your body at all times. If you feel bushed, didn't sleep enough, worked too hard or notice that weather conditions are hazardous, or for whatever reason you don't feel like running once in a while, then don't.
Go out slowly, take a walk, or stay home.
