Tried to do it slowly. 4 miles at 4mph. So I finished in 1 hour. My feet are fine. Ran in Injinji socks which I think will not survive if I do this again. Last 3 minutes I bumped it up to 5mph; it was easy.
I will get one of those Vibram shoes one of these days. I guess it doesn’t matter much what I get.
