We can pretty well deduce the race and the medalists using the eventual winner as a fixed starting point.
This is how it's going to go:
Starting from the gold medalist: he'll leave himself to the back of the pack at the start - no surpise there. Moves somewhere at 700-900 like he did in the semis, to make sure the pure kickers like Andrews don't get to surprise. A smooth cruise to victory from there. 3:36ish if you must know.
Kiplagat: tries all he can, hangs with the winner but unfortunately has no kick to match that of the others from such a relatively slow pace. Comes in 6th.
The young Kenyan: same for him - will not be a match once the kicking starts. He seems more of an endurance type - the Caleb 2.0 was a good comparison. Beats Kiplagat, though, for the 5th place.
Centro: positions well like always, kicks for home well. Beats the Kenyans from planet Earth. He'll medal all right, eventually, but he will not be standing on the podium in Beijing.
Makhloufi: has to settle for the bronze this time.
You can deduce who this leaves for a well deserved silver. He has learned from the semi and positions himself better this time around. Kicks like Vasala in 1972 Olympic 1500m final. BTW, it's remarkable that even though he and Vasala are from opposite sides of the globe, and 50+ years separated in time, their training philosophy is the same.
