So I ran on Leif Erikson today and I LIVED! I ran in my VFFs, 4.5 miles, in one hour -thanks to a lot of flatness. I ran on the end farthest away from NW Portland, off of Germantown Rd. I can DEFINITELY see why people would not be fond of running barefoot on it. It's not he sharpness of the rocks, it's the shape of them, and the fact many are hidden. The rocks are shaped like mounds, and many are hiding under a layer of mud. Hence, they are just waiting to ram themselves into an unsuspecting arch. This run was with another running group -cuz I am a traitor- and one of the dudes in the group is a barefooter/minimalist. And he has even read Ken Bob's book. I told him he should run with our group some time. Muah-ha-haaaa!
