NO! Robert McKeague of Villa Park, Illinois (a retired accountant) completed the Iron Man Triathlon in Kona, Hawaii in October of 2005. This was his fourth Triathlon and the most difficult. One hill took 7 miles to get to the top. Robert was the oldest person in the 27 year history of the Iron Man. Robert was 80 years old. You may now want to run triathlon but you can exercise. We train people in the 70's and 80's and it is amazing to see what they can accomplish.
