Half Marathon Training Update, Week 1

I just finished my first week of training runs for the Tucson Women's Half Marathon!  I've been thinking about signing up for the run since I heard about  it a year ago and finally decided it was time.  I'm ready for a new challenge and excited to have something that I'm doing just for myself.
  Here's this week's stats:
Total distance this week: 15 miles
Longest single run: 5 miles
