Backpost 1/Campus laps -- Tue. March 18

This was my first effort at getting back to running, and while it felt great, the results were pretty disastrous. I met Mark for a couple of campus laps, and we ran as planned, two laps. But for whatever reason, the next day first my back and then my shoulders (intercostals on the right) went into chronic spasm so I couldn't do anything. Muscle relaxants for the rest of the week, with the attendant dopiness and bed rest; it also gave me a bit of an aversion to trying again. Here's the details of the pleasant but ill-fated run, which consisted of two laps on a chill evening:

Time: 36:40
Distance: 4.42 miles
Speed: 7.2 mph

Comment: Not sure why such a pleasant run, barely under 8s on level terrain, messed up my back so much. Other factors involved, no doubt.
