That's actually a good strategy for both barefoot and huarache running.
But don't be stuck on doing a specific amount of distance. The key to barefoot/huarache running is LISTENING to your body (especially your feet, obviously). You may want to do a mile, but if your form isn't good, you may be hurting after 100m.
The idea is to use any discomfort as a teacher. And the lesson is always the same: DO SOMETHING DIFFERENT SO IT DOESN'T HURT (your feet like to yell ;-) )
Michael Sandler from http://www.BarefootRunningBook.com started with a 100m run… then 200m… then 300m… and made a slow transition until he could do 10-20 miles without a problem.
BTW, the joke I have with some barefoot coaches is this: They'll say, "Take it easy and don't over do it!" And I asked, "Have you ever met anyone who was able to 'not over do it'?"
They say, No. So, I ask, "Then why give that suggestion if nobody can follow it?"
You'll over do it. Guaranteed. But from that, learn what "pulling back" means ;-)
