new target

Hi all, I'm Chris from Newcastle (although I work in Kent Monday to Friday ). I'm 40 this year and currently weigh in at around 19st.i have made the decision that next summer I will complete a Olympic distance triathlon. When I was younger up till around 26ish I boxed at a good amateur standard and always fancied triathlon but never did it. I'm now massively overweight and have my eyes fixed on the triathlon next summer. I am currently running 4 miles (40 Mins) 3 to 4 times a week. I would be really great full for any training program tips or advice from anyone who cares to share.

Thanks
