Levy Loop/38th Street Loop

I walked the Levy Loop this morning in 28:00.06, and, starting at about 8:45 p.m., walked and jogged the 38th Street Loop in 25:09. I think I jogged for a total of nine minutes. I don't know why, but I have throughout my running life, since I was in the ninth grade, felt better running at night. I don't think it has anything to do with the weather, because it holds true no matter the season. I don't know.
