I am currently a sophomore in high school. My pr this year was a 18:15 for the 5k. Let's say that I train my hardest, doing anything that will get me better, (hard training, stretching, weight lifting, lots of water, breathing exercises). What could be the absolute fastest that I could be by next August?

(P.s. I want to be running a lot harder, longer, and more every day of the week then average trainers)
