I've been wanting to do this for a while (so has my boyfriend) but I am a little terrified I might kill myself. lol Race day us October 4th. If I do it I will most likely sign up some time during the summer. So I am going to give myself a little weight loss challenge in this thread and update it until race day. If I make significant progress by July, I will sign up... if not... I will wait until August to make a decision.
