Thanks I have had the opportunity to search the forum and have found lots of topics in regards to my question. I am sorry for repeating this but I am thankful for everyone taking the time to answer the question. Thank you again for your input, it's very encouraging to hear that it is possible. I have actually set my goal to compete in the iron man in 2010. I applied to try the eco challenge with the SWAT team I was on but the guys backed out, good thing I think I would have had my ass handed to me.
Thanks Frank
