It isn't physics, it's physiology. Due to the influence of ATP-CP metabolism, both the 400 and 800 are best run as positive split. From 1500 on up, even or slight negative.
Ajee always looks smooth, but that final straight looks incredibly easy for a near-PR. She is in AR condition...now.
I think she will. Nobody in the world has negative split a 1:57.
Even and negative splitting are faster than positive splitting. 800m runners seem to think their event defies the laws of physics for some reason and love positive splitting.[/quote][/quote]
