i think a lot of people run in college just to be part of the team (more so on the d3 level) and they enjoy doing it as a team so then when the team is gone they stop running altogether. I don't get how these people ran in the first place though, cuz most of them claim to not like running at all, yet they run. And when college is over they pretty much never run again.
For the rest of people who stop running after college i think most people are too concerned with "moving on in life" which i think is a ridiculous concept. Moving on in life doesn't mean you can't still do things you love. Life doesn't have to stop for you to have a career.
I feel sorry for those who complain that they have no time to run and the only obstacle is work. A career plus a family would make it hard, yet plenty of people still train that way. But if a job alone takes up so much of your life that you can't fit a run somewhere in the day then in my opinion thats buying way too much into the idea that work should be life.
I mean each person has to choose what makes them happy and maybe for some people spending all their energy and time at a job is what makes them happy. But i am surprised that more people don't keep trianing after college, since no one should be near their peak at the age of about 22. I mean when you are getting out of college that is the point in your life when you should be really just starting to find out how good you can be. That is basically the very beginning of the peak running years. I mean assuming you don't go immediately into a full time career AND get married within a couple years, which most people don't, i'm surprised more people don't actually see how good they can get.
I'm a little bit out of college and I can't wait to see just how good i can become at running over the next 5 to 10 years. I wouldn't really want to be married for at least 5 more years and I'm not too concerned about having a career that makes other assets of my life disappear since i'm just out of college and have some 40+ years to work. Afterall i only have probably less than 10 years to reach my running potential. So that is more of a priority than a career is. There is much more to life than work. Of course i bet some people will reply with theres more to life than running, but we all know thats just silly. I enjoy a nice balance of 40 hour work weeks with a good amount of working out as well as hanging out with friends. Not too hard if you want it.
