I’m thinking of throwing my hat in the ring for the 2012 Olympics, I’m not a bad sprinter although may not be able to manage 100m so maybe the 20m sprint.  I’m sure there’s nothing in the rules that says it has to be people entering.  After all, if a team of dogs went to the world cup, England may have done a bit better. There’s no way a dog would let the other side get hold of the ball!
