Friday’s episode of RocketBoom featured Race Walking.  The gentleman in the show claims to be able to walk a mile in 6 minutes.  It is worth a look.

 So, what is the difference between walking and running when you do a mile in 6 minutes?  Well, it all comes down to form.  There are two rules that must be followed to be considered walking.  First, you must maintain contact with the ground at all times.  Second, the knee of the supporting leg must be kept straight from the time it touches the ground till the time it passes under the body.
