I saw the race and the replays. Nobody seemed to have a great top end today. Asafa got out of the blocks very quickly and looked to have a decent drive in which he and Bolt put a gap between themselves and the rest of the field. They were pretty even through about 40m, when Bolt slowly started easing forward. In the last 20m or so, Asafa gave up time to everyone else in the field, and Blake closed the gap on him a bit. Asafa looked a bit sluggish. Bolt looked a bit sluggish. Lemaitre’s technique was pretty bad.
Not the best quality, but for now:
