Didn't you just describe sports in general?Then they add a new 'sport' every so often, like skeet shooting.
Perhaps the next will include 'Tractor Racing' 100 meter, 1000- meter both women and men category plus under 50 hp and turbo class.
But then they drop some of the original contests like shotput discus etc.
It is just a big 'mine is bigger than yours' contest.
