It’s a talking point now but will be forgotten when the action starts at the meet. One thing which may go missing is the stark comparison clear to see when an ordinary human sprints against one of the medal contenders.
The pre-qualification or “classification stage” is only set for the 100m because most nations enter their freebie into the shortest race. It may not prevent the likes of a John Steven Akwari from plodding home hours after the winner in the marathon…so the documentary directors won’t lose all their “human interest” angles.
