So I've been running the 1600 since middle school track, and I would usually come first or second in middle school and then when high school came around I could only at best get like 3rd or 4th in a dual meet and usually like 10th, 11th, 12th in invitationals. My PR in middle school was a 5:19 and as of right now in 11th grade it is a 4:47. My mileage is about 20-30 mpw. Should I adjust my racing strategy and start out slower instead of being aggressive or is it my training?
