Took a tumble in Istanbul, but back on my feet in Chicago

Recently I became acquainted with a young lady from San Jose who is also a runner. She told me yesterday that she was back to running five miles twice a week. I became somewhat embarrassed and went out and ran about 3.5 miles today. Slowly getting the feeling back in my feet.
Right after we landed in Istanbul a couple of Saturdays ago, I raced a student up the steps of a hill and took a couple of falls. This hurt a bit, but slowly the running is coming back to me.
