Competitive Swimming to Varsity = Possible?

Hello there, I am a late bloomer in swimming because I was not exposed to the sport until the Beijing Olympics... I started swimming with a swim club back in 2008 and I love swimming for all its worth. I'll be joining two swim clubs this coming fall twice a day - three times a week (ie. morning and evening). I'll also be taking swimming lessons at a local community centre (can't afford private centres). However, I'll be turning 21 years old by next month! It's not a problem but I feel it's a big obstacle because many athletic swimmers are exposed to the sport since they were kids compared to me who recently just started. I want to swim competitively as soon I become a competitive swimmer (obviously)... by then I would love to join a varsity team at a university... then again is that too ambitious? I never focused on a sport until now and I am really motivated to do this. What should I do? Is this a reasonable goal to achieve? BTW: I also love to run... I don't get easily as tired and I could pretty much run all day if I want to... So, I'm starting to routinely run in the morning and in the evening. Am I pushing myself too hard? PS: Im from Canada, if there is any difference in terms of potential of reasonable expectations of Canada/US varsity swim teams. Let me know your thoughts about my situation. :agree:
