I've just, casually, picked up interest over the last few years. A member here competes though I'm not sure how his "league" is set up.
The county has a park that's about a half of a mile from the house and they have a course I've played several times. Well, attempted to play. If it's not a real thing, then people have been playing a game for centuries that isn't a real thing either: billiards. In both cases it takes a skill to manipulate an object; be it a ball or disc. (Park has bike trails, water park, you name it...not bad for $30 a year.)
This was intended to be about the game...since you've weighed in.
If you put a man and woman, of equal skill, throwing a disc, the man will win every time. There is a distinct advantage in upper body and core strength. This is negated very often by skill. Much like the game of golf. But, at the core, there is an advantage.
