A sport for kids who are unathletic. They can run fast for a long time (for the most part), and thats about it. In elementary school they were picked last for soccer, football, kickball basketball, etc. because they lack hand eye coordination, and a general mental capacity to anything other than run in a straight line and hop over the occasional rock or two. Humans have evolved to run, they think doing something natural is somehow a sport.
1. I didn't make the cut for any of the sports teams so I do cross country
2. Nah, I didn't wanna take P.E. it's too hard, just join cross country.
