There Were No Acorns in The Garden of Eden

The last two days of running have been a bit of an on-road barefoot breakthrough for me. I usually do the bulk of my barefoot running on grass, with maybe a mile total on the road. Yesterday I decided to just go for it, and my ran consisted of about 4 on-road barefoot miles and about 2 more on grass and dirt. Today I ran on the road in the dark barefoot for about 4 miles, then put shoes on for another 3. I have been running just as fast as I would with shoes on. It feels great, except for the acorns!
