It is definitely doable.
I do 600 pushups every day.
I did 1000 pushups for my 66th birthday in December.
Took me slightly over 1 and a half hours.
I didn't drink anything, but it was indoors.

Too many pussy comments on this thread.
I’m with you, tomorrow I turn 69 and can push over 500 in my circuit cycle sets in an hour.
And that’s in 80 plus degree temps.
