This guy deserves no ink.
The average person can NOT walk fast at 12 mph. That's 5:00 pace.
That's probably just a careless error. You probably meant 12 minute pace.
There, too, you're wrong. I'm a pretty experienced power walker--not a speed walker, but a power walker. I carry my arms high and keep a high cadence. And I have a very hard time walking 3 miles much faster than 14:00 pace. That is very fast. 12:00 pace is impossible for the average person.
