Saturday June 8 (easy)

Went to the South Field at night and jogged an untimed run. I felt so wonderful that in the middle I broke out into a few spontaneous striders that turned into full-bore sprinting through tall grass and thin artificial light. Afterwards, I stretched out excessively before returning home.

This seems to have been unwise. My right knee was hurting walking around later that night, in the fleshy area in the back of the knee. It felt slightly painful but mostly weakened.
