This morning, I explained The Great Lunch Run Experiment and promised a bold new world full of lunchtime jogs through the mall in Washington D.C. Unfortunately, it didn't quite work out that way.

Fact is, I played a casual game of soccer yesterday with my roommate. We went to the high school and kicked the ball for a good 45 minutes. Trust me, I am not used to kicking a soccer ball, and it was evident immediately as I stretched on the sidewalk outside Stride Nation headquarters.

I began to break down just north of the White House, stopping in front of an Andrew Jackson statue. Walking was worse, as my shin had completely seized up. I gingerly walked back to the Stride Nation headquarters, took a shower and went into the office to get back to work. Talk about a crushing blow to the lunch running experiment -- we will see how I feel tomorrow, but it may be pushed off until Wednesday.
