There's no question Rose has the strategic edge over the two Stanford girls. I posted that a couple of weeks ago. The recent results don't mean much in comparison to the fact that Rose will inevitably get stronger and therefore be able to sustain that front running style. At that point the closers are stuck. They expect the speed to come back. It does not.
However, the loose speed is always stuck with the predicament of when to unleash. Rose made the classic mistake here of pushing too hard during that third 200. That myth needs to be eliminated from 800 conventional wisdom, especially from broadcasters like Dwight Stones. It is the worst possible move for the typical frontrunner to burn that third 200. You've already done the work and established lead and advantage. Why give it away with a suicidal acceleration so far from home?
Ultra elite freaks like Athing Mu can push very early on the second lap. For the typical 800 frontrunner and even at Rose's level you need to save energy early on the backstretch. The big jumbo boards make it easier. Relax and look up there. Allow the field to come back to you a little bit. Then take off again late on the backstretch. You'll stun the trailers by separating from them again, just as they think they are about to swallow you up. And with only 220+ to go you'll have plenty left.
As soon as I saw where Rose accelerated I knew she would be vulnerable. She needed to wait another 50 meters minimum. Kipyegon is a 1500 specialist but Rose should watch clips of her. Kipyegon is a master of relaxing on the backstretch then accelerating just before the 200 mark, leaving no doubt by the top of the stretch.
