Then, I joined the Air Force. Guess what their test of physical fitness was?--a timed mile and a half run. I thought the mile was painful. The mile and a half torture test was an annual reminder of just why I had sworn off running.
I gave running another shot when I became unhappy with my increasing waistline and my soaring cholesterol levels (thanks, Mom, for passing along that heritable trait) in my early twenties. I was mostly cycling at the time to lose weight and had myself on a very low fat diet aimed at some unreasonable body weight goal. I may have been running on and off for all of two months when I started having hip pain that then showed up on a bone scan as a calcium beacon. After being misdiagnosed as bone cancer (you have to love the military medical hobby shop), I found out I had a stress fracture in my femur.
Fact! I was not built to be a runner. This excuse carried me through 15+ happy, non-running years.
