As you can see from the picture below, Carole has actually dropped her chalk and is preparing to punch the head off the clown. Therefore, Carole wins (or the Clown if we're using Olympic standard rules).
I don't think I've ever jumped over proper hurdles. My school was too tight to bother with them. We rarely did athletics anyway, which is a shame because I was much better at that than football. I was probably the fastest person in my year but never got to put it to any use.
I did used to jump over the arms of our living room armchairs when I was a hyperactive child.
