Taking running to the next level

Weight loss is not my only goal to accomplish.  About 2 months after having my son, I decided that I wanted to take my running to the next level.  I have ran off and on since high school, but it is primarily done just to quickly lose weight.  It seems to be the best form of cardio that gives my body the quickest results.   The farthest I have ran was for my final exam in a running class in college.  We had to complete a 10k in some amount of time, but I don't remember how long.

Running is something that gives me a feeling of accomplishment after each session.  I push my body pretty hard, yet there are times that I am flat out lazy while running.  I need to get over this laziness that has taken over my mind and body for the past few weeks because I want to complete a half marathon and then maybe someday a marathon (we shall see how the half goes first).  I have looked into different training schedules and have found one that will work me up to the half.  I started it before vacation, but have yet to begin again since returning.  Originally, I was going to sign up for a half marathon at the beginning of November, but due to recent changes in a friends date to tie the knot I am looking for another one.  Which is not a big deal because I would prefer something in January or February for the simple fact that it is much cooler here in Texas during that time.  

So, time to suck it up and push myself.  I am going to start training(again) after this 4th of July weekend and I will be signing up for a half sometime soon.  Any half marathons worth looking into?
