Years ago, when I started running, it was no walk in the park. Evolutionarily speaking, I didn't think my body was built for endurance exercise. I started by running one lap around my college track. I remember it clear as day. It was spring of my senior year and my friend and former roommate (a runner) encouraged me to get rid of the freshman fifteen by taking a few laps with her. That first quarter of a mile was the longest jog of my life. I felt like I'd never make it around the circle. And, what a pain! When I got to where I started, she told me to do it again! As a compromise, I walked a lap and then ran a lap. All in all that day I may have clocked about a mile but it was a start. As I continued to run (or really jog), I continued to have the same sensation: that every step was like trying to pull myself through quick sand. But I set some goals, like walk a lap, run a lap, walk a minute, run 10 minutes, etc. and after a summer, I managed to run five miles without stopping....
