What is the minimum age to compete in the Ironman triathlon?
Ironman is divided into aging-groups. The first group is 25-29 so I assume that this is the starting age. Ironman is separated into national subsedies, so you might ask your local representative for further information. You can see a list of Ironman-subsidaries at http://en.wikipedia.org/wiki/Ironman_Triathlon Sources: http://www.ironman.
