Left knee

Left knee has been reliably starting to hurt exactly 2.5 miles into any run.

Sunday (after a long run on the Saturday) it started hurting right away. Yesterday though I covered a lot of ground in Boston running for the furnace part, and going to Chinatown on foot from the Roxbury/Dorchester area, and the knee never hurt at all. My left foot hurt some, but then the shoes I was in had no souls, at all– rubber long fell off, just the foam or whatever.
