Hi, I am a junior in high school currently running 4:06 for the mile and trying to see if I have a shot at breaking my school’s 1500 record next year. The record is 3:50.84 set in 2002, which I know would be a low D1 time nowadays and is certainly fast for high school but am not exactly sure how fast 3:50 high is/was considered. Could someone explain it a bit?
