Listen To Your Body
Even when your training is well planned, if it’s also challenging enough to push you toward a true fitness peak there will come some times when you feel unexpectedly run-down. When this happens, heed the warning your body is giving you and take a day off, or at least replace your next hard workout with an easier one.
Many runners find it difficult to pull back and recover in response to unexpected moments of accumulating fatigue, but it is usually the best choice. If you exercise restraint and pull back today, you will probably feel strong again tomorrow or the next day. But if you stubbornly persist in training hard despite your body’s warnings, you may enter the downward spiral of overtraining and find that it takes weeks to climb back.
