Thought I'd stop at 2. Figured I'd push it to 3.5. Did a 10K.

Foreign that I felt it in the lungs. Moved like molasses for the last mile. Calves were acting like they hadn't been run on before.

I could feel the strain in the foot for the first mile or so, but it largely vanished. I'm sore in other places now, which may be masking the original problem. Will have to wait and see how things shape up tomorrow, I suppose. I tried to focus this time on not limiting my landings to the balls of my feet, and to allow the whole foot to land (in order to try and more evenly distribute the impact). Don't know if that helps.
