I remember hearing that the average adult male walks at about 4-5 miles an hour. I walk at about that and I am 5'9".Eric the Orange said:Well I got a tread mill and after a brief warm up period I set it to 2 Mi/Hr which is my basic walking pace. So I'd guess it'd be like 30 mins. So I find it odd that it would take 13 mins, 'cause that would mean you were walking more than 4 Mi/Hr, which would mean either your very tall or you have a very fast walking pace.
Someone can feel free to correct me but a light jog is like 5-6 Mi/Hr on an average human (or 12-10 mins to the mile). So if you walk a mile close to that methinks you were probably walking faster than you would normally. Sometimes referred to as "power walking".
