I never thought I could do something like this...but I did!!!! I lost about 63 pounds between 2009 and 2010. I realized how much better I was feeling and that I can do more than I thought was possible. I suffer from asthma as well--so the challenge has been a big one. I was down with an asthma episode for a week during my training--but it didn't stop me this time. I ran the entire 13.1 miles in 2 hours 5 minutes (2:05) without walking once! So believe in yourself and you will do things you never thought were possible!
