I stumbled across this website at the end of the summer and though everyone should see it. Maybe you've seen it already but if not, you need to check it out. Track stats galore! World record progressions, all-time lists from every country and a lot of haven't even checked out. I was a track stat junkie in high school so I am sure some of you will enjoy this!
