When did it only become a one-mile run as well? Hell, even my 53-yr-old fat ass could (almost) run a mile in 6:40, depending on who/what was chasing me!
Back during the Stone Age, I could knock out five miles in a half hour. A sub-9-minute mile-and-a-half run was expected when I was in AFROTC...
It's go time, buttercup, so grab your jock...if you need one!
