I ran from the Farrah house in Millbrae out the Sawyer Camp Trail North extension (dirt then paved part) to the trailhead with parking along Skyline, then back, taking Skyline instead of the dirt trail because it was too dark. I did 3 x 33-34 fairly fast strides (in <21 sec. each) on the way back, after I was fairly confident that my left calf would be okay. My legs generally felt good, although the chronic pain at the top of my right knee cap was there to some extent for most of the run.
