This. "Being black" -- that is of West African descent (sprints) or East African descent (distance) -- does appear to be an advantage, statistically speaking, but it's certainly not an insurmountable one. Hicham el Guerrouj is not black and is the fastest miler ever. Sebastian Coe crushed his black competitors. Yuki Kawauchi won the Boston Marathon. And so on.
But there is potential for a "decently trained" male (not elite in the slightest by male standards) to "become female" and rewrite the history books on day one. This is the issue. The gulf between sexes is WAY greater than the one between races.
