5 Ironman in 5 continents by the age of 50

Good morning to all the triathlete or future ones . My name is Marco, I am new to the forum turning 47 in few months and I have a dream, finishing 5 Ironman in 5 continents by the age of 50. I do consider myself as an average normal guy but with a huge passion for triathlon. I will attend my first Ironman next year in Italy (Ironman Emilia-Romagna), anybody did it or is planning to do it? Other reason of this thread is to connect with triathlete that share the same passion and maybe have the chance to train with some of them. I am living in Krakow (Poland), so if you are in the area please drop a line and meet for some good training .
