Give up? Seriously Cheserek does not know how to give up.
And the arm flapping everyone witnessed? That is exactly what happens with him any tine he is/was distressed or completely fatigued in an over the edge effort . Saw it a lot in HS racesm chasing wildly in DMRs out in 1:59/2:00 and in allo out efforts in stretch runs.
The reason no one saw it yet, if that he was well within himself in every blistering last 200-300M he ran to win.
This race ,pace really really fast for an all collegian race was stiff right from the get go at about 4:16 high? and he still ran 56.x in a 13:18 race with last 200 probably 27 flat pr so?
He just got beat by a better guy and a guy who has run under that before, Cheserek never had and in the end it looked like it.
