I've been a good, patient, nearly saintly Barefooter since May. I can run 10 miles and only need a nap in the afternoon for recovery - no pain and no strain. 9 minutes a mile or so is an easy pace that I can keep up the whole way. I'm just starting to itch to go faster. My more sensible self is telling me to just cool it and stick to slow and steady. Run for the running and don't get cocky. The other part of me remembers FAST and wants it. Is it too early for me to start incorporating a speed component in my runs? What might that look like? Does anyone care to comment?
