I'm a freshman that wants to run a sub 5 minute mile. Not the metric mile. Last year I ran a 5:43 with about a month of training, hobbling around because as I later found out, I had stress fractures in both of my legs. During cross country season, it got even worse and I couldn't even walk normally. Despite that, being stubborn as hell I decided to continue the season. I was running about 25MPW. With possibly the worst form ever leaning into each side to cushin the blows in 80 degree weather my best time was 21:30. After healing I started running again but putting in many more slower miles for about 6 weeks. I've found that to be the most affective way to run without injuring myself so far. Now during preseason I feel I can run much faster and with much better form as last week I ran 3 800's around 235 pace and it didn't feel like I was really pushing myself so today I tested my 800 and got 227 probably still not all out. I'm not in great shape and wondering if in 4 months I can pull out a 5:minute mile or close to it.
