Half Marathon on the Treadmill!

I woke up so early and no matter how hard I tried, I just could not sleep.  Too much on my mind.  First I went to the post office to mail my last two Christmas items.  Then tried again to sleep - once again impossible.  So I said, what the heck, I have a little extra time so I think I will do a long run today.  So I ran a half marathon.  13.1 miles on the treadmill.  I watched 2 episodes of Seinfeld and 3 episodes of Big Bang Theory on the TV before I was done.  It may be boring but it's all I've got when it is 25 below zero and dark outside.  Not conducive to an outdoor run!
