I broke my chain climbing Pinehurst this morning. I walked the bike up to the top in my cycling shoes. Jessica came with the car and the dog and my tennis shoes 15 minutes later. She parked, I stashed the bike in the car, and we walked the dog on a single-track trail in Oakland hills, I, now shod in tennis shoes. We walked out about a third of a mile and back. Not sure what possessed me to attempt this, but the foot has felt significantly better, as I've been nursing it for the past couple of days. During the walk it felt OK. I made sure to walk cautiously and slowly and came through unscathed and inspired. But no brisk mile-long walks on hard surfaces in the near future. Not yet.
