Light infantry foot mobility standards?

Ft. Bnning, under Maj. Gen. Latham in 1976 required every IOBC class to do 25 miles without pack, but with rifle and pistol belt and canteens, in 8 hours. […] Upon my arrival at B Co., 2/327 in Feb 77 I was told that B Co. had done 25 miles in four hours a year before with one SSg. dead of a heart attack.

That’s a passable marathon pace without boots and the rest of the kit.
