I would love to experience the personal satisfaction of one day- completing the Kona ironman. In the ultimate test of insurance, the ironman consists of a grueling 3.86km swim, followed by a Tour de France length bike ride of 180.25km, and then to bring it all home, a marathon run to finish (42.2km).
I think that the achievement in successfully completing an Ironman is one of the most impressive human feats to reach. In order to finish the event, an individual must be in superb physical condition. The three legs are guaranteed to drain every molecule of energy in your body. The thought of having to run a marathon after riding over 180km... does bring a cheeky smile to my face :)
One day... I would love to complete the Hawaiian Ironman.
