I enjoyed this missive immensely! I have never been able to run very far or very often. But after reading about barefoot running I decided to give it a try. And I discovered that I had to run slow enough to avoid the bumps and pebbles and glass and such that my heart and lungs were able to keep up! It was quite a revelation. The longest distance I ran barefoot was 8 miles and I was one proud son of a bitch, let me tell you! As I am dieting and working out I am back to barefoot running (well technically not since I wear $6 water shoes but it is still a far cry from $90 shoes and a pair of socks).
