I remember a few years ago Jordan Desilets PRed in the mile byt like 10-12 seconds and ran 4:01 at an indoor meet at Kent State. I was wondering if anyone else has made this kind of jump before? what contributed? new training? or did everything just finall "click" for you?
ok cool
Senior year of high school I was running around 4:40 consistently, and was able to drop it down to 4:21 my freshman year of college. I had my blood tested over the summer, found out I was anemic, and when I started taking iron supplements I was able to get in much higher quality training, and dropped my PRs significantly. I ran 10:08 in the 2 mile during outdoor of my senior year, and an 8:45 3k indoors, freshman year.
