How far could the legions travel in a day

[Matthew Amt]

that 20,000 steps a day, at my stride of 2.7 feet, is only a little over 10 miles per day (current). I am 5'11" tall (180cm) so I think it's unlikely the typical legionaire's stride is much if at all longer than mine. Is it possible that 'steps', in this case, meant double steps, ie, a full 'left-right'?

Right, the Roman pace or "passus" was 2 steps, total length of about 5 feet. Hence the "mile" is from "millia passus" or 1000 paces, 5000 feet.
