The Walk Kansas team challenge doesn't start until Sunday, but it's a good idea to take a look at what you're doing now. I recommend printing out the daily log and filling it in this week, just to see where you're starting from in terms of exercise and diet. I started keeping my data on SparkPeople again and am realizing just how low on exercise and freggies I've gotten.
A clear vision of what you want to achieve makes it easier to do all the little steps. Walk Kansas has a S.M.A.R.T. Plan for Healthy Living that each participant should fill out. I asked my Walking on Sunshine team turn theirs in to me, but you might want to post yours on the refrigerator or the bathroom mirror so it stays foremost in your mind.
