I am an elementary school teacher. I have gained 35 pounds since I turned 50 years old. I have had breast cancer twice, and went through chemotherapy and radiation treatments, along with having 22 lymph nodes removed from my left arm pit one year ago. I have a goal to run a marathon before I am 60 years old. That means next summer. I am working to get in shape to run a half marathon at the end of August. I ran a half marathon two years ago.
