Half Marathon Training

I started training for a half marathon with the local YMCA this past Monday. Tonight was our first "long" run of 3 miles. I ran it at 27 minutes and was the third person to finish which was nice considering I am always the last person at my Saturday morning running group. So, I am thinking I will make the switch since it's nice to actually be 'in' the group rather than coming in 30 minutes after everyone else. Did I mention that the Saturday morning group is all former highschool trackstars. Yeah, I'm not. Anyway...
