every week, i run a mile in p.e. a typical 4 lap mile. im 5'4 120lb. and i run it in around 9:30. :[ i asked my teacher how i can improve, and he said just run more often. so im planning on going for cross country this summer. :] ive always wanted to have endurance and cross country is perfect. as im in cross country, im gonna get a personal trainer at a gym & work on little things. but for now i guess i just need to run ore often. so if i were to run 5 days a week, just a mile, how drastically would my mile tie increase??
