12 miles in 3 hours is the air assault pace. it is only 4 mph, but depending on your physique, primarily your mass and height, it can be either easier or more difficult. since it's a female, he's probably small and weighs no more than 140 lbs. this isn't any to sneeze at but it also isn't "badassery". the motherfuckers out there doing this in under 2 hours, they have my respect.
