What is a word for a group of contests? It doesn't necessarily have to be a real word, just something that's concise and obvious, possibly something like decathlon but for an indeterminate number of events.
To add more details, I am not so much focusing on the group of contests themselves but instead on the context in which the contests take place. I believe league is the best I've come up with so far. i.e. an athletic league like the Major League Baseball vs Minor League Baseball.
I was also liking Olympiad, but the idea is that concept I'm going for is supposed to be an indeterminate time period and indeterminate number of games.
