It would be nice to see Bernard Lagat race sub-4 one mile; smart money says he cannot.
I am certain that a 45 year old man training for a 2:12:xx Marathon is easier on the body than a 45 year old man training for a sub-4 one mile.
Only one 45 y.o. man has ever run 2:12:xx and none ever ran 2:12:10 or less.
