Early one morning just as the sun was rising...

There was a moment this morning when I realised I was actually enjoying my run. I was about 1/2 way through, 3 miles or so in, the sun was shining, I was on a very (very) slight downhill bit and there was nothing wrong with my knees, my feet, my head, my ipod... Will this moment ever come again? It didn't last all that long, but it was truly very nice.
