December Run Challenge - Run 100 Miles in a Month

I have been out of running, real running, for months.  So, to jump start some Winter training, I decided to join up with Dailmile.com and run in one of the Challenges.  Fast forward to today, and I'm 6.2 miles into my 100 mile goal for the month.

This month of running will be Heart Rate based running instead of pace.  I've been out of it for a while so my goal (besides running 100 miles this month) is to build endurance.  I have a lot of slow miles ahead of me.
