because they'd run some insane time, and everyone would know for sure that they are doping, instead of just hinting at it.
you know, like mo farah did with his 3:28.
Interesting as to whether Defar would have beaten Dibaba with a 2.41 last KM .Dibaba has certainly been able to close faster than that previously off a similar finishing time.
In New York last year Dibaba beat Defar in 14.50.81 with a 2.39.72 last KM.
Dibaba and Defar are so cool.....brilliant runners!!!
at their peak 5k
~ 56.0 / 1'58.5 ->
this is virtually no different from the gap mo with his 3'28.8 is from the 3'26.0wr that they are from the chinese 1500wr ( do the ratios )
