I just wonder what relation do we have between Competition and a Rider.
We know that a competítion have many riders in horse jumping..

But can a rider paricipate in many horse jumping competition but not at the 
same time.
So do we have a many to many or one to many in the connection between 
Competition and Rider in horse jumping?
