How do I efficiently come back from a stress fracture? Hi, I am a 16 year old girl. I ran my first meet of the season in the 1500. I think my time was 6:20 but I slowed down by almost 40 seconds. My PR is 5:42 from last year in grade 10. I had taken a couple of months off due to a stress fracture in my tibia, and only returned to running in late February. I really want to make it to provincials in the 3000m, which is in a month. 

My previous 3000 PR is 11:37. How should I train to prepare for provincials, or is it going to be impossible to PR this year? I currently am running 5 to 6 days a week, and on the days I don't run, I lift and use the rowing machine. I do 2 track workouts a week, 400 repeats and a tempo run, and go on easy trail runs for the rest of the week.
