Pre was aerobically gifted and a driven hard worker from an early age. I went from 5:04 my freshman year to 4:32 my sophomore year. Then from 4:15 my junior year to 4:09 my senior year. My fastest mile was my sophomore year in college of 4:03. I can't imagine ever running much faster than that, maybe 4:00. But I was a 1:57.0 800 and Pre was the same type that could run 1:53-54.
Pre ran 3:56 his freshman year in college and eventually 3:54.
I would say he was a phenom that if put into a pro mile race his senior year in high school like at the meet named after him where Don Sage ran 4:00, Pre would been capable of 4:00-4:01 and possibly 3:59.
Hanging near the back going out in 59.0. 1:59. 3:00. Then competing the last lap in 59. He would have been cabable of that in the race conditions top preps recently like Sage, Webb, Mangness, Verzibicus got to hang and have something left.
