The finishing time doesn't matter. They opened in a 76 second 400... no one was PR'ing or even coming close to one in this race. If you didn't already know this, I'm not sure how you made your way to letsrun..
But I say again Dibaba is world recorder with a 3:50 pr and can't even run the 4:09 to win. Yeah ok. And has a "toe injury" or cover up for fear of being tested at the meet. And her coach is telling her when to go in the race, which he hasn't done before. Cause he knows that she's gonna run differently/ less strong now that the effects of the drug are less.
That fact that these women closed sub 2 is amazing. Dibaba closed in like a 1:58. Still INCREDIBLE. Lets see how that compares to the womens 800m final.
