Four years ago, I felt lucky after escaping one of those terrible 2-mile runs. I hated running; it was just something that 1 came easily to me. At that time, if you had told me that I would one day run a marathon, I’ d have told you honestly that I had a better 2 of winning the lottery（ * * ）. The turning 3 came when I met Mrs. Green. She was fifty years old, going through chemotherapy（化学疗法）for her cancer, and still managed to run 30 miles a week. I thought that if Mrs. Green could run 6 miles at a time, I could run at least two.

The miracle is that I had the 15 to start.”
