Today's run: 4 mins running, 1 min walking, 4 mins running, 1 min walking. I got into a little rhythm with my breathing, in time to my footsteps, and that seemed to help. Plus my ipod was out of batteries, so I wasn't subconsciously trying to match the rhythm of the music. Progress has been made.
Knee integrity: 95% and holding, Captain. I get the occasional twinge, but I suspect that's just instrument noise, sir.
