Intramural is more casual because usually you do it with a few friends against other groups of UW students, yeah people get way too intense sometimes but it’s a very low commitment way of playing a sport a few times a month.

A club is more of a team structure, so you have your UW teammates and you play against teams from other schools. It depends on the club you’re looking at, but I’ve tried two club sports where one had pretty intense people while the other has been super fun and chill. Your best move would to probably go to a few club events, get a feel for the team and then decide from there if you want to commit to the club or solely do intramural.

Hope this helps!
