Heel spurs?

Look how my running has tapered off again... But I have had heel pain again, and I haven't found a source yet, since I started running again about the same time as the new job and with the couple weekends of standing around watching parades.

Today I felt my heel for the first couple steps, but by the time I was finished it was all gone. Can't feel it now at my desk.

Anyway, 8° and raining, ended up only doing on lap - thought I was going faster because at the second corner I was already breathing heavy, but maybe that was environmentally caused, as I am sitting here with that half-coughing urge in my throat. Rough timing didn't show any speed up - started at :05, got the mail and came inside at :11. Packing running accessories for Munich!
