My doctor said exercise or medication. I downloaded C25K. Six months later I ran my first 5K and cried at the finish line. I'm off the medication.
"I'm a below-knee amputee. I was told I'd never run again. I found C25K, adapted the plan, and finished my first race. Now I'm training for a half marathon."
