D3 College Athletics

Hello I’m a rising senior and I wanted to know more how running can impact my college admissions.
I run XC and Track my times are:
5k-16:31
800m-2:00s
400m-50.9s

Are these times close to being able to help my case at any D3 schools, if so how do I show the colleges I’m interested in running for them and also maybe get support from the coaching staff for admission at a more prized academic school?

I think you’re fairly close to being competitive in a couple strong academic D3 conferences - NESCAC and UAA come to mind. Certainly close enough to get your calls returned. Do some research, figure out which schools and programs interest you - and be able to verbalize that to a coach - then email / call coaches with your times, test scores and GPA.
