A guy I work with ran in high school, he was best at track where he ran the 400m. He said he never, ever raced anything besides the 400. His 400 was 50.xx. He also did cross country, it was 3 miles, not 5k (this was late 70's), he ran an 18:20 best. Just got me wondering what he would have ran the mile in with these times? He said he never really ran the mile, and couldn't remember what he ran it in when he ran it in PE. I was just curious what 50.XX 400m and 18:20 3 mile would for 1 mile.
