I’d say the thread title is a bit of a misnomer as well.
The video shot from behind in the air shows that both Asafa and Usain are nearly even for ~70% of the race, at about 70-75m Bolt starts pulling away until they’re through the line. It seemed like Asafa visibly tightened up over his last 20m. Other than that, that’s the best race I’ve seen from Asafa in a while when there was another thoroughbred involved.
