My fatigue friend is back.
For about 20 years, I was kinda tired, not sleepy -- tired.
Training hard leaves you with out the emotional "pop" friends seem to have (unless they too are in training). 

After an unusually hard session, you might have muscle aches, but most all days you are more laid back than your personality might be if not training.  Things seem less important (except of course the run).

My yearly goal was 50 miles a week or 2600 miles. I always exceeded that, always.  I would do more for weeks leading to a marathon I wanted to well in.  Not just miles, but intelligently scheduled training.

I kinda got hooked on running because it buffered the rage in me at the time when I lost my boy.  Ten years later, I guess it was my lifestyle.

When I retired and moved from my friends and running environment, I stopped running and worked on the new house and yard.  The years have been good.  I am fat and happy.

Now I want to see if I can race again.  There is no rage, no ego, and so motivation is less.
It is an interesting endeavor for me.  I observe myself headed to the final finish line.  As my coach, Sheehan said, "Life is an experiment of one".
This endeavor is painful, but also fun.

Being tired all day is not productive.
I need to get a grip, and like in the olden days, run in the evening.  Then I can just go to bed.
That is hard to do that these days.  If I put training off, might not do it.
