6.3 kilo at 6 min/kilo barefoot!?! Pretty nice! When are you going to start running Orienteering races barefoot?
I don't think that will ever happen! Although, I am sure Native American's could cover ground quickly in the wooded forests!
We just need to sew you some hard-soled leather moccasins. However, shoes need to be especially tough when there are locust trees around.
I guess Indians didn't have to deal with nails. But I have never found a nail just lying out in the woods anyway. I wouldn't want to find one the hard way though.
