Lets get this restarted!!!

So I saw this post on my MRTT (Moms Run This Town) site to join this weight loss challenge (Run With Jess). I want to drop about 13 lbs so I thought I would do it. Now I am feeling nervous and scared because I have to hold myself accountable to do it so I don't look or feel like a quitter to my boys. I have never been able to stick to a diet which is why I am nervous. I also have been very lazy with my running because I love running in races not the training, and we have been tight with money so I haven't been able to do that many. But I WILL DO THIS! I will do this for me first then my husband and my boys! I will start running 3 times a week! The town I live in has tons of really hard hills so basically that is what I have to run all the time! UGH!!! I hate hills and they totally mess with my times! For those of you that don't know me I am SUPER COMPETITIVE!!!! So a bad time on my run = bad mood after, not a good mood like you should have! Soooooooo I have to get over it, run, improve and get rid of this beer gut! Am I giving up my beer? No just going to work my ass off!!!! Literally! So this is my new info Your BMI is: 22.9 Target weight range: 101.2 - 136.7 lbs Current weight is 125 lbs. Height is 5' 2"
