That is light years the best summary in the thread. Nobody else even bothered to account for the situational influence.
This race was set up for Habz. It's probably the only time in his career that will happen. They moved a non-Diamond League race into the Diamond League window for him. Every variable cooperated.
I knew it wouldn't be a normal race when Stefan Nillessen settled fairly close to the lead in a fast pace. He's never done anything like that.
Jakob has often bemoaned the lack of ideal pacing in some of his record attempts, that he'd like to have something similar to what El Gerrouj enjoyed. This is as close as we've seen to that, with the meet director screaming at the pacemaker and then the pacemaker screaming encouragement to Habz. Habz ran near the minimum distance. Those measures have been available in horse racing (trip handicapping) for decades and have finally emerged in this sport.
Coming off the final turn with 150 to go I expected Habz to flatten out. But then the key moment, just as runfrancisco described. This wasn't solo. Koech was right there. In a solo race Habz was favorite to flatten out. But you could see the determination etched on his face. The infield camera angle was perfect. He kicked again. It's the most energy and motivation he'll ever have in his athletic life.
If he ran 3:28 but lost the crowd would have been deflated and the commentators offering rationalizations. Instead Habz had his defining moment. Never a sleepless second guessing. He's not a 3:27 runner. He ran 3:27 on that day.
