I think I want to run track in college, but where do I start?

You are very good, I think good enough to run in college. Your times are all very good, but I especially think your 100m and 400m are great. (I'm a bit biased on the 800m though because a girl in 8th grade at my school ran a 2:17, she's so crazy good) You would do very well on a 4x800 team as well though. Keep it up, and don't listen to the guy above me, he must think you're a guy, because your times are phenominal!
