I never ran track in high school; it seemed kind of redundant, trying to throw my teenage body over hurdles and things. I had enough of those set up inside my head; I didn’t need to go looking for more. But there is a concept from the sport I learned only later that you can apply to most anything, whether you’re an athlete or not. It’s called a running start, and particularly if you’re dating — especially if you’re new to it, after a long time out — you’d do well to learn it. And don’t worry; it doesn’t involve unflattering nylon shorts.
