Welcome back my friend fatigue

The last few days I have put on my knee braces and ventured out for some low key runs. Nothing spectacular but, I noticed how tired I was after I finished. That is the feeling I miss. That feeling of being tapped out and able to sit in one place, letting the aches of the run settle in my body. My mind settles into neutral for a while. No more miles to run for today, no more promises to keep...
