Hhmm.

I ran down the hall to catch a ride to lunch.  Flat out ran.  It wasn't far, but it was wide open.

Now my shins are a little sore.  It wasn't but 2 hours ago.  That shouldn't be happening.  Odd.

I'm getting this weird, anxious feeling that I HAVE to run, but I'm worried about hurting myself.

Odd.  Very odd.  I'll probably feel better in about 3.4 miles.
