I'm callng bs on this one - not a race or lap either Eliud Kipchoge's unofficial last 400m in his INEOS 1:59 Challenge run was approximately 49 secondse
Seem to remember cacho once doing 49.xx in a non Olympic race probably some reporter exag.
Moron. Ryun last 300m started in lane 2 so covered 310m while accelerating.
So 36.4 is intrinsic >>^^35". With curve fitting of each 100m segment this is intrinsic ^^48" last 400 but on cinders and leather clog spikes so on next gen mondo with supa spike we have intrinsic ^^46 second last 400.
Based of this with lap curve fitting algorithms it is obvious that Ryun had intrinsic ^^3'22" 1500m ability so full 100m ahead of Coe and stray cats.
Only a moron could not see that.
the video is as clear as mud you cannot see the 300m mark on the track
