I didn't want to do it. I had to drag myself out there. And then drag myself up and down my "Hill of Difficulty" over and over and over again. I had to wonder why on earth I was going through all that pain! But then, I came to the end of my three miles of intervals and somehow, I felt so much better. All the pent up stress from the past several days was gone. And lo and behold, I was smiling! Running is magic!
