Easy, controlled row through 30 minutes. (20 spm.) Then took it up to mid to high 20s.
Note (injured)
During the last 10 minutes, at the top of the slide, I had three moments when something felt like it was flipping over in my ankle, producing fleeting, sharp pain. Not too bad, and temporary.
Note
During the evening, at TNT birthday dinner, I began to notice that the sharp pain in the ankle was constant, and quite noticeable whenever I would flex the ankle pass vertical. The pain was sharper than anything to date.
