   ...and double that would be 5 feet, which is pretty close to the   
   back formed 5.28 feet.  However, modern estimates are that the   
   Roman mile was actually 4680 feet, so a slightly shorter stride   
   than the modern US Army version. Since, so far as I know, mondern   
   people are, on average, somewhat taller than in the past, this   
   pretty much works out.
