Major stress today, family crisis. I won't go into it but after a day of hand wringing and worry and being utterly helpless, I decided to go out for a run.
It's a rest day and swelteringly hot so I decided to just leisurely jog. I didn't get that fatigue after five minutes or even get out of breath. I was able to gather my thoughts and get things into perspective. I didn't time myself but I did break into a sprint for about ten seconds and thought sod that!
I feel so much better now, it's not solved anything but that knot in my stomach has gone!
