That is just how I feel too! Excited but scared. I've only told my husband and sister for now. It just sounds crazy. I've always hated running but it might be because I was so overweight. I'm on the road to a healthy lifestyle now and this will be my crowning moment. Every time I read someone elses story about doing the 1/2 marathon I cry. I try to picture myself walking through the castle and then finishing and finding my family waiting there for the thinner and healthier new me.
I'm glad that posting this has helped everyone. I printed it out and hung it in my office at work to keep me motivated.
