Awfully familiar scene - Semenya not even breathing hard immediately after the finish, everyone else hands-on-knees out of breath.
Semenya wins 50.40.
In that case, we're going to see a 49.6 by Semenya.
Or put some 49.7 women in the race and see what happens.
Will the W5000 WR go?
Will the MSteeple WR go?
Will ARs fall in both of those races?
