My name is Jennifer and this is my second time joining the group. I think the biggest challenge for me is that I have to change my unhealthy diet. The exercise part I'm definitely on track because I am training for a half marathon (Whidbey Island Half Marathon April 10th). I plan to keep a food journal because a lot of the food I put in my mouth...I am always telling myself..."I shouldn't be eating this because it's not good for me"...but I eat it anyways. Not good. I think my eating unhealthy is a bad habit that I need to break...big time. I want to lose 18 pounds...so that I could be a faster runner! Yes, I am a competitive runner (I compete against myself only to set a Personal Best and to break previous race times)...and for me to reach my race pace goal...I have to lose the extra weight! Wishing you all success!
