I was debating whether or not to sign up for one, but I asked if my sister wanted to do one with me and she and my brother in law both were interested, so I decided to go for it. I'm excited! I have been running more lately and I already pretty much do 5Ks every time I run, but I haven't done an actual "race" since I was 14. When I registered, the application asked if I had an inspiring story, so I said that I was once 400 pounds after battling a decade-long depression, but have now beat depression and lost 180 pounds.
