COMMENTS: Mildly sharp pain in left knee area in first mile, then again when going uphill. Stopped 1/3 way up MC hill. Walked, then jogged home. Iced, massaged and ibuprofin at home. Will rest Monday and check out Tuesday. Felt like quad tendon was culprit. To LP in 19:20, footbridge in 38:30, back to LP entrance in 58:30.
