If you are not responding to training as you should...working hard and getting nowhere...always look at your overall health first. Lack of sleep...poor diet...not enough pure water...too much stress...too much worry...too much thinking...can all impede an otherwise perfect training plan. Your body needs all of its resources to adapt to the stress of training. If you are in a compromised state, the training just makes you tired...not stronger.
If you know Ed Whitlock...probably the greatest age group runner of all time...the first man 70 years old or over to break three hours in the marathon (2:54 at age 73)...then you know how relaxed he is. When you hear him interviewed, he practically puts you to sleep. It's not that he's boring...he's just really relaxed. I believe this is one of his great secrets. He goes with the flow. He hasn't got his foot on the gas pedal all the time like so many of us do.
So this is just a reminder...to myself included...to look after ourselves. No need to push all the time. See to your basic needs. Then you will feel more like training and the training you do will have benefit.
Look upon yourself with a soft eye....easy...
