It's tongue in cheek, sort of. ;) I've seen these people and you know you have too. In fact, long before I read this article and the descriptions, I vowed never to look spastic running. I try my best to look 'athletic' instead, like I actually know what the hell I am doing. Hey, the key phrase there is TRY.
Here's me trying in the 5K last October. What do you think?
Yours in fitness, Kate
