I didn't do my planned ride today. I was feeling a little stiff after yesterday's ride. I rode my road bike (instead of my 'cross bike) since the weather was decent, but now my IT band is tight, and so is my knee. Not sure if this is from the bike change, the shoe change, or if I need to tweak my fit. Anyway, listening to my body, and letting it rest. No reason to push it and make it worse.
