Introducing me...the newest newbie!

Well I'll start by telling you all my name is John. I'm 42 and in "average" health albeit a little overweight. I think the most difficult thing to do when deciding to take the first step in anything is setting attainable goals. So I did this yesterday. My immediate short-term goal is to run in my first 5k on 10/23/11. Now I am NOT a strong runner at all and I think this will be my most difficult event in a tri so I am going to focus on that first. I have been running a bit off and on since the spring so I modified the "Couch to 5k" a bit to start me where I am physically while also getting me up to the 5k level. My longer term goal is to participate in a tri next summer. I don't really know if starting from scratch at my age makes this an impossible goal in this time frame but I'm going to give it a shot. My next step is to announce this to my family and friends. This will hold me accountable and keep me going too. I'm only holding off on this until after I see my doctor on Thursday to make sure I'm cleared medically to start training. Either way, I will be doing the 5k! I'm nervous about all this but I think I've got a good basic start point and I will build from that. I'm buying a new pair of running shoes today on my way to work. Cheers!John
