What country are you from?
Most sports in the US have organized sport till whenever. larger colleges have typically 3 levels now. NCAA, Club (which has national championships and travel) and then intermural, which is still pretty competitive, and well 4 pick up games for most sports.
And when I say most sports, Track and Field, Hockey, Soccer, Baseball, Football, lacrose, bowling, volleyball, handball, ultimate frisbee, Triathlons, biathlons, shooting, (guessing gymnastics, dancing) definetly swimming, and on and on all have adult competitive options
The US. Played college sports at all three levels.
I just cant see other countries having things like college lacrosse that have no ties to a professional league/team - while providing the athletes with professional level facilities.
I assume if you go to a school like oxford, london school of business, university of melborne, etc. they dont have anything close to SEC football or even ACC swimming.
Like where do most UK runners train for the olympics? do they come to the states (and run at florida/oregon)? Where do Dutch handball players train? Where/how/when do curlers find rink time? Cyclist I know join teams.
I know the Brownlee boys went to college, but did they do track /swim/etc. at college like andy potts?
