I guess I heard about this, but this is an interesting article: https://www.nytimes.com/2017/06/15/sports/olympics/jarmila-kratochvilova-800-meters-record.html I don't know what to think about it, really. On the one hand, there's probably no doubt that Katochvila and others were doped to the eyeballs. But on the other, somebody clean is going to catch her eventually, and it'll be all the more special. And note that FloJo's records would be wiped, too.
