My first Iron Man competition

I was talking to one of my friends, and he told me that this september, there will be an iron man 70.3 competition in Syracuse. He wants me to join. I have always wanted to do a competition of the sort, but never have actually gone through with it. I would say I am decently in shape, could definitely be better though, but the only thing I am terrified about is the running. I am a sprinter. I don't think I have ever ran more than 5 miles at a time, and never at a race pace. I started looking at websites for training for the iron man, but have not really found what I'm looking for.

Does anyone have any training schedules or websites that they think are pretty good? With my super busy schedule, I barely have time to get on here and enter all my information, let alone do extensive research. Any little help would be awesome. Thanks!

I've never been so determined to do something. I am so excited to start
