What is Circle Comp and Rippin Run?

[Nitrox]

I know this is just something everyone should know, but I couldn't find anything (here or footbag.org) that told me what these are

I know what Sick 1/3, shred30, and routine are...but no clue what Circle and Rippin Run are for tournament events

Sorry for being a tard
