Wilma. I've run a couple halfs and an handful of 15k and 9ks. Best schedule for you is the hal higdon half marathon training schedule. Just google it. Make sure you follow it pretty closely, especially the long runs. I was doing the full marathon training program (training for the half) and even managed to keep my running up when I had to go to NY for my grandfather's funeral.

I ran 15 miles in central park that day.
