5 Miles today on the Treadmill

Not moving very fast but at least I did get in 5 miles today on the treadmill.  Feeling really bored with indoor running lately.  I just can't seem to find the motivation that I need.  Maybe there is something to this negative effect of constant darkness.  I won't see the sun until January 1st when I get back home.  It went down November 23rd and won't come back up again until January 17th around here.  But normally that never seems to bother me.  I can't quite get motivated to go outdoors and run in the snow with the current wind chill of -35, in the dark!  Feeling extremely lazy!
