I have just spent the last two months transitioning into my VFF's. It has been pretty rough, but the pain/discomfort has been worth it. I am now averaging 1.75 to 2.0 miles every time I go out. I usually take a few days off, but have been feeling like my body is being better to me. I stopped running on pavement as much, and I am running on a wood chip trail, with a dirt track nearby. I have in the past had terrible cramping in my right leg, but have tried new things while I run to lessen the severity of the pain. I will start posting my miles and trails that I run.
