okay im a high schooler that can run a 4:28 mile yet my 3 mile pr is only 15:53 do I have the talent to move it down and why do people that run only a 4:45 run a faster 3 mile than me is it that I have more fast twitch and less slow twitch, do I need to do more miles than everyone else or less, I also ran that 4:28 on 45 mile weeks, sometimes 50, I also included a 12 miler each week thanks
