I'm a high school senior. My best 5k time is 17:34 (last year), with a 2:12 800m and a 4:57 1600m from track last year. So far this year, I've run pretty close to my 5k PR after recovering from a big injury during the months of June and July. I think I can run 16:50s, 2:05, 4:40 by the end of my high school career.
If I ran D3 for a small school in college and continued to up my mileage from 50 (where it is now) to around 70-80 after a couple of years, what is the fastest I could possibly run a 5k? Under 16? Under 15:30? As a pretty much averagely talented kid, what is my potential?
