Cold!

So cold outside today.  -15 with a wind chill of -40.  Of course I'm not going out there to run.  So I ran 5 miles on the treadmill.  I was having a hard time.  Kept getting pain in my legs.  But after about 3 miles, it all went away.  I didn't run yesterday even though I should have.  So I'm not sure if that extra rest day was a good thing or not.  But at least now I feel back on schedule.  It might be warmer next week so if that happens, I'll go back outdoors to run.  The treadmill is a good workout but doesn't bring the good feelings that I get outdoors in the fresh air.  But sometimes I just don't have much choice.
